Seems it should work. google "PS/2 to USB linux" present
Linux 2.4.XX, Sun Solaris 8 compatible devices.

This is good cost cuting for tea and cofe drinkers :o)

happy to hear it :-)

so Andreas haven't updated his XFree binaries yet,
i'll probably have to add it to the howto

that's probably OK,
but the question is whether the init scripts 
can live with it

althougt what happens if you decide to change some hardware,
filesystem ?

it's more flexible to have most hardware compiled as module's

probably your init script doesn't like
built in support for usb,
this is the case for mandrake as well
if usb is built in the kernel, not as modules,
service usb doesn't start -- it doesn't mount
usbfs and there might be some issues with 
certain usb drivers
you probably have to mount it yourself then

it happened to me under debian too :-)
but i don't think it's a good idea to add this to the howto,
it's devfs issue and has nothing to do with bruby/ruby-2.6
and there is a link to the devfs howto

it's higly recomended to switch to gdm,
as it does obey the specified start/stop order
and the later is really important to avoid some lock ups
with certain graphic cards on start/restart/ shut down
of the X servers, and it does help to retain the VGA console

no idea, 
if it works under non ruby kernel, it should work under bruby/ruby-2.6 too

may be searching for this particular adapter "+ linux" on google will
give you some answers

best,

svetljo

PS.

please check if putting
Option "DRI" "false" 
for your second card works OK
with DRI activated for the first card
and drop a line
(i'll add it to the howto if it works)

not sure, but the best way to find out is to try :-)
if it works you might use single configuration file
and still have DRI activated for the G450

Yihaaaa! It works! disabling DRI and using the -prefbusid option did the 
trick! Thanks a lot!

But then, since there are a few issues it would be good to understand, 
let's take it anyway...:

Yes. I think I once read that if you build a kernel for a specific 
system, and there is something you use all the time, compile it into 
the kernel, if you use it just occasionally, compile it as a module.

Dunno.

Yup... 

BTW, here's one point you might want to add something like this in a 
Troubleshooting section of your HOWTO:

Q: e2fsck complains I have a bad superblock after I enabled devfs. In 
fact, it appears all the superblocks are bad, and I'm scared. What do I 
do?

A: Make sure devfsd is running.

:-) This put me off for several days...

I have automatic mounting enabled in the kernel.

Yup, as I said, it works! :-)

OK.

I guess I might as well ask right now: I was thinking about buying a 
gadget where I can get two PS/2 ports from a USB-port, like this:
http://www.clasohlson.no/images/products/N/hi/A/324024_Xw4.jpg
I have no further specs on it, but do you guys think it would "work"? 
The idea is to use one of those for the second keyboard and mouse.

do you use his kernel binaries ?
have you cmpiled the kernel yourself ?

do you have the kernel configuration file ?

IIRC he used to build all input drivers as modules,
but in your lsmod i see only the driver for usb controler
no mention of input driver modules

you must have it 

/proc/bus/input/devices llocks perfectly OK
do you have in /dev/input/ 
mouse0, mouse1, event0  to event3 ?

smth debian specific ?
have you installed devfsd ?

does your bootloader line contains " devfs=mount",
or if you have compiled your kernel have you enabled 
automatic mounting of devfs ?

may be try adding here "-prefbusid x:xx:x" for each card,

another idea woud be to switch to gdm (cause it follows
the order of starting X servers as specified)
and try exchanging the start order
in your command line first is started X1 then X0,
with xdm/kdm you can never be sure which one will be started 
first, but with gdm it's up to you to specify the order

i think i've got smth similar when i found out that DRI is not supported on
multiple graphic cards
(IIRC primary G550 , secondary SiS6326 but i think both X servers started
the second without DRI of course)

this probably just information,
that the driver found additional device which is not specified in the
current
layout

Re: Local Multi-User X (?) problems

[Svetoslav S. <sv...@gm...>]

Hi Kjetil,
that's the best bug report i ever got :-)
and i'll have to reread it several times
which might take me sometime :(

in the mean time several notes

1.) 
you can not have DRI acceleration on more then one graphic card

you have to disable it fully or leave it activated for one of the cards,
and disabled for the other(s)  -- two XF86Configs

not sure, but this could be the reason for the problems

2.)

you've written to Andreas,
have you asked him which XFree-PrefBusID patch he uses for 
his XFree binaries ?

i've the impression he uses the first version of the patch
and the only valid way to activate multiple X servers
is to pass on startup  " -prefbusid ...." 

please check this two things, 
and i'll get back to you soon :-)

best,

svetljo


PS.

from kernel side everything seem pretty OK to me,
but there is smth strange with X setup

Local Multi-User X (?) problems

[Kjetil K. <kj...@kj...>]

Honorable Kernel Hackers,

I hope you do not mind a "user"-question from a newbie...? I'm working 
to set up my system according to the XFree Local Multi-User HOWTO, and 
it says in the final notes that I could try here if I need help... :-) 
I've been working on it for a couple of weeks, actually. I guess I have 
a little too much of the Perl Programmer's Hubris, but then, it is the 
only way me and my girlfriend can afford and have space for another 
seat, and she needs to get some work done to... :-) Also, I don't think 
what remains is a kernel problem, more likely an X problem. 

I think I've been through all the pitfalls that one can possibly be 
going into. Since I'm on Debian Sid, I've been bothering Andreas 
Schuldei a lot. I'm using his great packages. 

To do the short version first: Everything seems to work fine, except 
that when I try to get KDM to launch the two X servers, the first 
server comes up fine, but the second does not. Instead, the server 
takes the whole CPU, but apparently does nothing. If I kill the second 
X-server with -9, it comes back up and then it runs fine on the second 
screen, but the first locks up and the first X server runs along. 
There are tons of messages like:
(EE) MGA(0): [dri] Idle timed out, resetting engine...
in my logs afterwards.

Now, for the details:

My system has a Matrox G450 DH and Mystique card. Since I'm now going 
for a 2.4 kernel (I'll (re)turn to 2.6 later, for sure!), I'm not 
trying to use the second head of the G450. Rather, I'm trying to use 
the Mystique for the second user. 

I have a Logitech Keyboard on the normal PS/2 port, then a cheap 
keyboard on the usual mouse PS/2 port. I have two mice connected on the 
USB ports. I might want to change this setup later, but I don't want to 
buy a USB keyboard. 

One of the things Svetoslav asks for at 
http://tldp.org/HOWTO/XFree-Local-multi-user-HOWTO/final_words.html is 
contents of /proc/bus/input/devices, and since this sums up the setup 
rather nice, I paste it here:

This looks good, doesn't it?

(I'll paste in just the things that I assume is relevant, the rest I'll 
attach. Hope that's OK. XFree86.[12].logs I had to trim, this mail is 
large enough as it is.) 

I've configured Xinerama, and it works fine. I have preferred keeping 
the whole X config in a single file, so I take the approach with 
specifying different "layouts". I maintain four different layouts, 
"Simple", "Xinerama", "X0" and "X1". The two latter are the ones for 
the multi-user config.

They look like this:
Section "ServerLayout"
        Identifier     "X0"
        Screen      0  "Screen0" 0 0
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Keyboard0" "CoreKeyboard"
        Option "PrefBusID" "1:5:0"
EndSection
Section "ServerLayout"
        Identifier     "X1"
        Screen      0  "Screen1" 0 0
        InputDevice    "Mouse1" "CorePointer"
        InputDevice    "Keyboard1" "CoreKeyboard"
        Option "PrefBusID" "0:11:0"
EndSection


devfs is up and running, allthough there are some weird issues; 
specifically mount doesn't report that devfs is mounted, whereas 
/proc/mounts does. This put me off for a long time. 

It is easy enough to get X running on either screen with corresponding 
keyboard and mouse. Also, I have been able to run it on both, 
simultaneously, running 
startx -- /usr/X11R6/bin/X1 :1 -layout X1 vt8 & startx -- /usr/X11R6/
bin/X0 :0 -layout X0 vt7
I could type on both keyboards, it showed on their respective screens. 
Mice worked. 

So far, so good, it seems, but then I tried to get KDM to start them for 
me, by adding the following lines to /etc/kde3/kdm/Xservers:
:0 local /usr/bin/nice -n -10 /usr/X11R6/bin/X0 :0 -layout X0 
-deferglyphs 16 vt7
:1 local /usr/bin/nice -n -9  /usr/X11R6/bin/X1 :1 -layout X1 vt9

Booting up, things go wrong. X comes slowly up, but only on one screen.
Upon inspection, it is clear why it is so slow, because the X1 process 
runs at 99% of the CPU according to top. Other than that, things are 
normal on the display that is running, but obviously, the idea was to 
have both... :-) 

In syslog, I find things like this:
Oct 29 16:04:15 owl kdm[720]: Hung in XOpenDisplay(:1), aborting
Oct 29 16:04:15 owl kdm[720]: server open failed for :1, giving up
Oct 29 16:04:15 owl kdm[686]: Display :1 cannot be opened


I didn't really have much of an idea on where to start, but I noticed 
two things. One thing was that in kdm.log, I found lines:
(EE) MGA(0): Need at least 4608 kB video memory at this resolution, bit 
depth
(My G450 has 16MB, I don't know what the Mystique has). So, I tried 
setting the bit depth to 8 and the resolution for both cards to 
800x600. That didn't help, and besides, I run Xinerama at 16 bpp and 
1280x960 and 1024x768 respectively, so that shouldn't suddenly be a 
problem, I figured. Turned it back up. 

Then, I was in doubt whether I had entered the PCI bus id's correctly. 
The autoconfig I ran when making the Xinerama config had them in the 
form PCI:0:11:0, but in the examples, the PrefBusID strings did not 
have the PCI:-prefix. I had left it like that initially, as it seems to 
be that way in the examples. However, I see lines like
(WW) MGA: No matching Device section for instance (BusID PCI:1:5:0) 
found
(WW) MGA: No matching Device section for instance (BusID PCI:0:11:0) 
found
in both kdm.log and XFree86.?.log. Then, I figured, they should probably 
be the same in the BusID-field and PrefBusID, so I changed them to what 
they are now. That didn't seem to have any appreciable effect either, 
though. 

Then, I don't know what Primary Device is, but in XFree86.1.log (i.e. 
the log of the secondary card), I see
(II) Primary Device is: PCI 01:05:0
Yep, this is the ID of the primary card (the G450), but I don't know if 
the secondary card should care... :-) 

Well, I was pretty much out of ideas at this point, but I got the bright 
(?) idea that I would kill the X1 server to see what happened. Wow, the 
other monitor came up, and I could type at it an use the mouse and 
everything! :-) The state of bliss was short, however, because the 
primary display had frozen... Again, the X server had run off, this 
time the X0 server. This was what top looked like at some point:

 PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
  721 root      20 -10 54532  12m 1904 R 97.7  2.4  18:55.21 X0
  881 root       5  -9 19772 9516 1856 S  1.0  1.8   0:09.79 X1

So, apparently, I can only run one at a time, and kdm will restart an X 
server if killed, and the other will run off wildly... 

Well, that's about all I've got. 

I'll list a few of the pitfalls I've been in and send it to Svetoslav as 
soon as I get around to do it, to help others avoid them.

I'll be very thankful for any help you hackers can provide so I get this 
system up and running!

Best,

I use neither.  I believe these things are for multi-card
issues. (X server stupidly disabling other cards)
But I have only one card at this time, there are no
other cards there to disable via pci programming.

I use a BusID (not prefBusID) for the accelerated
server - it  is probably not necessary.  Just something I
added because I read about it, preparing for a future with
two cards.  Specifying the same BusID for fbdev goes wrong,
the server notices that it can't grab that card because
it is in use, and quits. 
Fortunately, the fbdev driver doesn't need to grab a card
at all, it merely grabs a framebuffer device and uses its
memory.

Come to think of it, "UseFBDev" doesn't say anything
about _which_ fbdev to use.  So I guess it uses the first one.
That could cause all sorts of strange bugs if the first one
isn't the right one.

They'll probably just tell me to do it myself, perhaps I
can get enough information to try.

Hm.  X already works well in a dual seat setup, wonder what those major
changes are.  DRI already uses a device driver, using another driver
shouldn't be a problem.  I am tempted to get a pci card and use a
chroot so both X servers can get their own "/dev/dri/card0" which 
happens to be different devices.   The problem is time, and
which pci card to try.  I happen to like matrox for their good
picture quality (sharp and no flickering), and history of good dual
screen support.

Any information about the "almost" part?  Are they sharing
something (such as 3D hw) that might prevent fully independent
use of the two heads?
The one thing I don't mind so much is shared clock/ramdac, I have two
identical screens so the ideal frequency and resolution is
the same for both.

I have little use for more than 2 seats, but I see how a 4-way

It is ruby-260t6-20030930.diff.bz2 on top of plain 2.4.0-test6
A search for ruby-260t6 turns up:
ruby-260t6-20031015.diff.bz2      (This is the newer one?)
ruby-260t9-CVS-20031028.tar.bz2   (test9 ruby? exciting!)

I don't know the differences between them, I don't usually
find much version-specific information.  I don't
think the 20031015 was available when I downloaded the patch.

I don't think matroxset makes a difference for _using_
the framebuffers, it only decides which one is visible
on what connector.  Framebuffer X (and accelerated)
works just fine "blind" if I mess up a matroxset command.

> can you try the earlier patch?
I suppose you mean the later one as I
seem to be using the earlier one?

That 260t9-CVS version seems even more interesting, unless
it is "work in progress" with known problems.  I'll
probably try that one first.

Ok. I will be glad if You test G550 with single console only under ruby.

Please apply this patch, witch allow one console per fbdev.
Secondary console init may lead oops on matrox g550.

i've beiing using it for a long time 
mga accelled + Nvidia TNT2 Nvdia GL libs,
but when i tried mga acceled + fb/ 2xfb
i can not get it running :(
probably i didn't played enough with matroxset
(
i remmember trying to get Miguel solutions before a year may be,
and X did started, but i loosed my mices ?
)

Hi Hi

Theoretically there are about 15-20 users(known to me) of such system,
and i doubt that someone complained about the problem.

there was a guy who wanted to get it running for some kind of commersial
system/ project,
i think he didn't needed multiple users, not sure about Xinerama, but
on the dri-devel list he got advised to ask for commersial support
from one of the developers's X releated company

IIRC the dri developer mentioned that no one thought of developing
such thing, and generally the core itself shouldn't be changed much,
but the X drivers needed major chages, and may be he could make it work with
certain driver
against a paiment

i assume almost yes,

they do have 2/4 G200/G450 chips with separate BusID's on them

which ruby-2.6 is this ?
the one with real multi-user console, or the earlier
with only multiuser X ?

if it's the first one may be fbcon might get confused
somehow by the 2 fb's on a single card, which might be
not properly initialized without matroxset that early
or might be Aivils did missed smth(but i doubt it)

can you try the earlier patch?

Strange. Normal is 5-10 sec VGA console output until
fb_console_init is called. After fb_console_init You
can read printk only on serial console terminal in case
fbcon is broken.

2.6.0-test6-ruby dies before the first printk if I do that, 
while 2.6.0-test6 works.  fbcon on matrox breaks somehow
with ruby.  I don't know what to do to debug this
further - adding printk's is probably not an option.

Thanks!  I'll do this if I ever get those

I used this machine single-headed for a long time.
All I did was to create a second config file (xf86config-4) 
for fbdev, and use matroxset-0.3 from Petrs site to
set up which framebuffer connects to what output.

I can set up a guest account on the machine, if you
want to look more at the setup.

debian packaged xserver-xfree86-dri-trunk from http://people.debian.org/~daenzer/dri-trunk-sid/
because I want accelerated opengl on at least one screen.
I got xdm working too.
From my /etc/X11/xdm/Xservers:

:0 local /usr/X11R6/bin/X :0 vt7  -deferglyphs 16 -nolisten tcp
:1 local /usr/X11R6/bin/X :1 vt17 -deferglyphs 16 -nolisten tcp -xf86config xf86config-4

The first server use the standard XF86Config-4
This runs the servers, but I had to modify /etc/X11/xdm/Xsetup
too to actually make the second framebuffer visible.  Whenever the
accelerated server starts, it configures the G550 to show the same
screen on both outputs.  Fortunately, xdm then runs the Xsetup script,
so that's where I put the following lines:
/usr/local/bin/matroxset -f /dev/fb/1 -m 0
/usr/local/bin/matroxset -f /dev/fb/0 -m 2
/usr/local/bin/matroxset -f /dev/fb/1 -m 1
1. line: disconnect /dev/fb/1 from whatever output it uses (in case it was using&blocking  output 2)
2. line: connect /dev/fb/0 to output 2, which is the vga connector
3. line: connect /dev/fb/1 to output 1, which is the DVI connector with a VGA converter.
The output numbers are really bits, so connecting a framebuffer to output 3 shows
it on both screens.  There's also a third output, bitnumber 4, but there is no such plug.
Perhaps the video out?  "matroxset" seems undocumented.

This setup means both servers get a screen.  A minor inconvenience is the way
both screens blink whenever one of the xdm's are reset.

Using BusID here doesn't work.  The two files are otherwise

Make sure you use matroxset so both framebuffers are visible.
You can do this without running X, cat a few megs of garbage
to both framebuffers first so they won't be all black.
Then experiment with matroxset.

Too bad.  Theoretically this should be _trivial_ for
dual-seat two-card setups, because the two xservers are
fully independent and so are the two graphichs cards.
I wonder what they are running up against.

Of course the much more common case of one seat, several
cards aren't that easy - but I'm not trying for that.

Which is why I'll buy a card if I believe it'll work.  Accelerated
2D on both screens is nice too, of course.

Well, 2.6.0-test6 (without ruby) works fine with
framebuffer console.  It dies only if I use ruby.

seems matroxfb low level device drivers is broken.

Under ruby patched only hardware independ abstract layer -
frambuffer console fbcon.c .
If matroxfb will run under vanilla 2.6.0-test6, then it
should do same under 2.6.0-test6-ruby

This is only way for dual head video adapters.
To start accelerated xf86 on both heads indepent
input You should write Your own XFree86 5.0.0 .

Current ruby support straight in kernel compiled fb device
drivers and fbcon. To test Your matrox figure fbcon into
kernel and reboot.
Without parameters /dev/fb/0 take over VGA and use
/dev/tty1 - /dev/tty16 device files.
/dev/fb/1 create extra console with /dev/tty17 - /dev/tty33
You schould add additional mingetty in /etc/inittab to get
login prompt on /dev/fb/1 .
For test I use Voodoo1 as secondary card and have got
success. Of course Voodoo1 is very special video card, but
suitable for tests.

IMHO You attemp kill fly with the cannon.
This project is created actualy for 2 separate X
servers. If You will start programms from 1st desktop

Even root cannot access X desktop.

How did you got it running?
i'm tring with no success quite a long time.

which version of XFree ?
which matrox drivers?

if i try to start accelerated X,
X doesn't want to start and is eating ~100% of the cpu
X on fbdev seems to start, but no output to Monitor

two things here:
1.) DRI doesn't support multiple cards
(and it doesn't seems this to be on the TODO list
 of the DRI developers)
only choice is to use Nvidia cards with the closed source driver

2.) even if DRI supported multiple cards
 all heads have to be addressable by the driver.
with Gxxx DH this doable only with fbdev driver
which doesn't support DRI, XV, .....
(G200/450 MMS series could work as they have
different BusID's, but are untested -- too expensive)

probably it's the matroxfb driver,
Petr (the maintainer) still doesn't like the new FB API,
and is still working on a more complete driver using different fb API,
the in kernel driver is not that developed and with limited functionality,
try searching lkml on smth like "matroxfb 2.5"

2.6.0-test6 ruby success with matrox G550, and some questions

[Helge H. <hel...@ai...>]

Yesterday I got two xservers running with 2.6.0-test6-ruby
Both screens are connected to the matrox G550.
The one running on the main console uses the normal
accelerated X server, and a keyboard connected to the mouse port.
The X config for this display isn't modified, it is
the single-user setup I always had.

The other screen uses the unaccelerated framebuffer driver
on /dev/fb/1, and a keyboard connected to the normal keyboard
connector.  Both mice are serial.

Framebuffer X was easy to set up.  The first attempt was right,
except it didn't work until I got the matroxset program
that must be used to decide which framebuffer is displayed
to which connector.  (The default is to see the first
framebuffer on both!)  I haven't made startup scripts
yet, so I start the second Xserver from an xterm.

I did nothing special with the sound setup.  Both
screens are positioned between a shared pair of
speakers.  The alsa drivers for my trident 4D NX supports
several simultaneous users and does its own mixing.

The long term plan is to use two accelerated X servers.
Ideally by getting acceleration on both heads - but that
seems very unlikely.  The second best solution seems
to be a pci graphichs card.  I am waiting, hoping to find
some pci card that supports DRI in such a way that
I can use DRI on both screens simultaneously.

The questions:
2.6.0-test6-ruby seems to hate framebuffer console, hanging the
machine before the first boot printk if I enable it.
Is framebuffer console possible somehow?
I currently need framebuffer in order to run X.  And a
console is nice to have in case I get X trouble.
I currently only have screen garbage until X starts.
Having some framebuffer consoles on the other screen
would be nice too.  fbcon also has the advantage
that it can be set up with the same video timing as X,
allowing console switching without waiting for the
screen to sync to another frequency.  

I use the kernel parameter "dumbcon=1" to tell ruby that I have an extra
console.  Is this documented anywhere?

problem with x authorization

[dave g. <giv...@ya...>]

I finally got my second X server running. Thanks for
your help.

But, when I start my second X server with the startx1
command (modified version of startx to start my 2nd
server), I get an error message:

Xlib: connection to ":1.0" refused by server
Xlib: Client is not authorized to connect to server.

So my X client, KDE wasn't able to start.

When I start the 2nd X server with the 'X' command, I
don't get an error message until I try launching
a program, like xterm, onto the display. The error
message is the same.

I've tried setting the environment variable $DISPLAY
to ":1.0" and then calling 'xhost +' just before I
start my second X, but it has no impact.

Also, do you know how to setup an X display that is
larger than the screen resolution (the Viewport and
virtual, options in XF86Config) ?

I can use virtual to set the size (Virtual width
height), but how do I control which part of the screen
X shows when it first starts? 

:)

If You have two keyboards, then You might test both with
1st xf86
startx -- vt7
with 1st keyboard. Then stop it an try
startx -- vt8
with 2nd keyboard same mouse.
Identic You might test 2nd xf86.

If You do not apply patch on xf86, then 1st xf86 freezy after
2nd xf86 start. You can use unpatched xf86 according docs.
Write this into XF86Config of both xf86.
Section "ServerFlags"
Option "PciOsConfig" "1"
EndSection

before start any xf86 do this:
echo "1" > /proc/bus/pci/hackvideo

I think You use unpathced xf86, which one donot allow 2 or more
concurent X servers.
Also Your secondary Nvidia rather will not work with default
driver "nv" shipped with xf86. You should install driver from
www.nvidia.com. Please read out about this:
http://www.tldp.org/HOWTO/XFree-Local-multi-user-HOWTO/
Nvidia GLX & DRI section.
If You simple install Nvidia drivers, then after instalation You
cannot use ATI Radeon GLX acceleration, instead only GLX acceleration
on Nvidia adapter.

if you are using the XFree binaries from:
http://www.schuldei.org/debian/bruby/
it already contains the patches, but the
patch that alows concurrent running X servers is
older version, so you have to pass "-prefbusid " 
to every X server you start

if you are using the XFree packages that came with debian,
try first what Aivils explains below

take a look at this chapters of the howto
http://tldp.org/HOWTO/XFree-Local-multi-user-HOWTO/mod_x_server.html
