linuxconsole-dev

User questions welcome?

[Michael R. <mic...@tu...>]

Moin,

I just subscribed to this list. I want to use one or more PC with some X 
consoles at a conference.
Because I have some problems with the AGP card I wonder if user questions are 
welcome to this developer list? It seems that there is no other mailing list 
consernig 'linuxconsole' than linuxconsole-dev?

Seems here is very few joiners :(
Strange problems pop up time to time.
Mulptiple X servers depends from video adapters and mainboard too.
Impossible cover all cases.

Feel free to ask, and provide details.  Are you trying to build a 
multi-console
machine right now, or are you planning one?   What exactly are the problems?

Moin,

I have to operate some 'surf station' at science conferences, so I thought 
it's a chance to test the backstreet ruby patch with several X servers.

I have:
 patched and compiled a 2.4.25 by my own
 A debian based Pentium 4 with 1 GB RAM
 X packages 4.3.0-0pre1v3 from http://www.schuldei.org/debian/bruby
 1 nVidia AGP card
 1 nVidia PCI card
 1 Matrox Millennium
 2 PS2 keyboards
 1 USB keyboard
 3 USB mices


The kernel is started with the parameter 'dumbcon=2' by grub

I followed the instructions from the XFree-Local-multi-user-HOWTO.txt (so 
far).

Now the problem: As long as there are only the PCI cards are build in 
everything is fine! I can use both consoles.

Therefore, I have these entries in my /etc/inittab:

# For we use "1-16", "17" and "18"
#X2:23:respawn: su - guest -c "startx -- /usr/X11R6/bin/X2 :2 -layout X2 
-xf86config XF86Config-4 vt7"
X0:23:respawn: su - averell -c "sleep 5 ;startx -- /usr/X11R6/bin/X0 :0 
-layout X0 -xf86config XF86Config-4 vt17"
X1:23:respawn: su - joe -c "sleep 10; startx -- /usr/X11R6/bin/X1 :1 -layout 
X1 -xf86config XF86Config-4 vt18"

But when the AGP card is build in, no matter if I try to start the 'X2' or 
not: the machine freeze in the second 'X0' is starting. The last lines in the 
logfile are
(II) Module fb: vendor="The XFree86 Project"
        compiled for 4.3.0.1, module version = 1.0.0
        ABI class: XFree86 ANSI C Emulation, version 0.2

My XF86Config-4 is attached. In the documentation the gpm with a special 
parameter is mentioned. But I don't use gpm. In an other docu the command
echo  "1"> /proc/bus/pci/hackvideo
is mentioned, but as far as I understud the HowTo it's not longer needed with 
the patched X server?

I even think about to write an article about this method, so every help is 
welcome!

=46irst You should try manualy all 6 variants of starting order.
startx -- -layout X2 vt17
then from xterm start secondary X server and so on.
Also for proper Nvidia initialisation mostly works
X -layout noprefbusid -probeonly
where "noprefbusid" is standard xf86 layout without limitations like
prefbusid. After "probeonly" nvidia kernel module is initalised correct and
user can start/stop xf86 any times.

Who knows how compatible is this set of video adapters. Also You have 3 pai=

for tests.

Patched xf86 does not need for hackvideo. Someone may have unpatched xf86
and will test linux-ruby anyway :) Sometime videoapdapters like prefbusid,
sometime hackvideo. We do not have report statistic.
Patched xf86 does not need for Option        "PciOsConfig" "1"

thanks for all your information. I got some GeForce II cards this week. With 
this combination everyting is running fine! Some minor problem like 
'shutdown' or competing sound access are not to bad.

Thanks for your answers

Do you have information about kernel 2.6 support? And information where such 
configurations (local-multi-user-X) are used?

X servers must downed in the reverse order of start. gdm do that.

Under Mandrake/Fedora exists /etc/security/console.perms
which contains device access permisions
Multiple sound card usage explains only my files
http://www.schuldei.org/aivils/eng-down.html
Check out Mandrake 9.1 files here.
No articles.

2.6 usage equals 2.4 usage.
In theory 2.6 have working fbcon . User may start two framebuffer devices
and each fb device have separate keyboard. Also matrox-dualhead owners can
use each head as seprate text mode console bounded with separate keyboard.
Reports about fbcon is very different. Low level fb device drivers may be broken.
fbcon new features are undocumented and breaks old school  multiheading,
where one user uses number of fbdev heads.
Multiple X servers uses aprox 5% of kernel console code so it is aprox 20 times
more bugless against fbcon.

this seems to use Miguel's solution after all 
(hope i didn't broke some trade secrets )

There's also a IT department in Skoda in Chech Republic
and in Izrael a school related project
but no information available on the net

both use several 4-headed boxes
