New I2C and machine probing method

[Matthias G. <mat...@us...>]

Hi,
I want to use some OF and kernel 2.6 features to improve device probing
in pbbuttonsd. Unfortunately I have only an ancient PowerBook so I need
your help to test the new routines on as many different machines as
possible.

I attached the source code of a short program. You could compile it as
follows:
 $> gcc -o of_probing of_probing.c

This program does three things:
1. detecting the machine ID.
   Any PowerBook user can test this feature. Launch the program and
   check if the machine ID is correctly detected on your machine. If
   you don't know which ID your machine have see in
     $> cat /proc/device-tree/model or
     $> cat /proc/cpuinfo
   Tell me if your machine is not correctly identified. PowerBooks
   before the G3 Pismo will get the dummy ID "1", because Apple started
   his numbering system just with the Pismo.

2. detecting the LMU I2C address
   The program looked for the "lmu-controller" in the device tree and
   read the attached data to find out the I2C address.
   This test will only have a result, if you have a PowerBook with an
   ambient light sensor. Otherwise the program won't find an LMU.
   If your machine definitely has an ambient light sensor and the program 
   won't find it, the device tree path might be wrong. In this case please
   send me the correct path or an tar archive of /proc/device-tree.

3. detecting of the /dev/i2c device to communicate with the LMU
   This test reads /sys to find out which i2c devices are available and
   which one is connected to the "uni-n" controller the LMU is attached
   to. Each found i2c device will then be checked for the LMU.
   The program lists all found i2c devices to the console and mark the
   device with the LMU connected.
   This test needs the kernel module i2c-dev to be loaded. If not
   already done, you could load the module with
     $> modprobe i2c-dev

I would appreciate any feedback.

 Thank you and Best Regards
   Matthias

I don't know exactly because I don't use the gnome power manager, but
there should be an option to configure what to do if the lid is closed.
Set this option to "nothing". This might help.

Re: Powerbook G4 - sleep on closed lid problem

[jean c. <tra...@gm...>]

OK, there is news from the sleeping-front:

I figured out that the gnome-powermanager was causing the trouble. If I kill the gnome-powermanager process, the system is able to sleep on closed lid.

Any suggestion how I could keep the powermanager from gnome and let the system sleep on closed lid?

Thanks a lot

Powerbook G4 - sleep on closed lid problem

[jean c. <tra...@gm...>]

Hello everyone,
first of all thanks for this great tool, all powerbook buttons worked right out of the box of my ubuntu-6.06-installation.

To come to the problem: My powerbook is able to sleep (the corresponding flag is set to 1) and it works all fine using "pbbcmd sleep" and as well if I log out (then there is the hybernate and suspend-option given on the bottom-left). However, when I close the lid of the powerbook (using Gnome) only the backlight is turned off but the computer does not sleep. I booted into the Kubuntu-live-cd and there it all worked perfectly.

Is there anything I can do about it? I read somewhere that deleting the gnome-powermanager would work??

Thanks a lot in advance
Greetings

In the synaptics sources I found that there is an option for a "Repeater"
device:

---8<---
#  Option       "Repeater"      "/dev/ps2mouse"
The Option "Repeater" is at the moment for testing.
---8<---

I enabled it and /dev/ps2mouse appeared. But I can't read anything from
the device with cat.

Is this in any way related to the "new virtual input device" you mentioned?

Yeah, not to get into a distribution flame war, but OpenSuse 10.1
seems a lot more polished than Fedora Core 5.

Anyway, if I understand you correctly, you are saying that glibc (on
my previous FC5 dist) was compiled against a different kernel version
than the one I had installed and was using to compile pbbuttonsd.
Makes sense, as I had recently done a system-wide automated update.

Doug

When compiling a usermode program, you must use the kernel header the
glibc is compiled against (those installed in /usr/include/linux) or you
might have problems. But you choose to switch to another distribution
which is, in my opinion, the best choice you could make.

Solved: Compiling on FC5

[Doug M. <dou...@gm...>]

I "solved" the problem. I dumped Fedora Core 5 for OpenSuse 10.1. It
has support for pbbuttonsd right out of the box. I'm guessing the
second error I was having with Fedora Core 5 was related to the
specific kernel installed.

Doug

I solved the error by with:

but now get this error:

Re: Compiling on FC5

[Kristian B. <kb...@op...>]

It seems like to dont have the kernel headers installed in /usr/include.
There must be a package named something like kernel-header.

[PATCH] fix crasher in ALSA module on newer PowerBook and mini

Hi Matthias,

Recently I came across a bug in the Ubuntu bug tracker, which described
a crash in the ALSA module. The bug is documented at
<https://launchpad.net/distros/ubuntu/+source/pbbuttonsd/+bug/39646>. It
is a crash which occurs on some of the newer machines which don't have a
hardware mixer. Essentially it's a (hard to track down) typo; the patch
is below.

It seems that you suffer from an inaccurate machine check.
Pbbuttonsd have to check now if you machine has a ADB trackpad or not,
because the last ppc PowerPooks have a USB trackpad and had problems
talking to an not existing bus.

Could you please provide the contents of /proc/cpuinfo to prove this

Wallstreet II / PDQ trackpad won't notap using pbbuttons

[Tommy T. <tom...@gm...>]

[Duplicate message; my apologies if this has come through more than once.]

I've been trying to track down a couple of problems I have had for
months after upgrading to Ubuntu Breezy. One has to do with the
trackpad intitializing at tap, drag, lock -- I opened Bug #25942 in
launchpad https://launchpad.net/distros/ubuntu/+source/pbbuttonsd/+bug/2594=
2

I only recently realized pbbcmd is not able to set the state of the
trackpad. When I use pbbcmd, it is setting a register, but NOT
changing the state of the trackpad:

$ pbbcmd config tpmode 1
$ pbbcmd query tpmode
1
$ pbbcmd config tpmode 0
$ sudo trackpad show
READREG(3, 2) trackpad settings tap drag lock
$ sudo trackpad notap
$ sudo trackpad show
READREG(3, 2) trackpad settings notap nodrag nolock

I just discovered the news at
http://pbbuttons.berlios.de/newsarchive.html and noticed that some ADB
code changed between 0.6.x and 0.7.0 -- maybe a change in that code
affected my hardware, because it was working fine in Hoary (pbbuttonsd
0.6.6-3ubuntu3). I have tried installing the latest binary in Dapper
(0.7.2-1ubuntu4) but so far its behavior is the same.

I am not experienced in C programming so I have had trouble finding
the place(s) in the source code that point to the adb... I'd be happy
to try some diagnostics and even compile a patched version if someone
can give me some assistance.

I'm running the binary from Dapper but the package didn't install
fully because I'm still running an older version of libasound2 -- and
I am assuming that's not relevant to this issue.

Here are some things I have looked at...

$ pbbcmd query version
0.7.2
$ pbbcmd query sysinfo
106
$ pbbcmd query identity

Test post from gmail

[Tommy T. <tom...@gm...>]

I've been trying to ask a question on this list for a few days but the
messages originating from gmail have bounced. Trying again!

I entered the question on the pbbuttons forum at sourceforge.net but I
cannot tell if anyone reads those!

As Kristian already explained, this is a problem caused by the
synaptics X11 driver. There are other programs out that filter mouse
events (mouseemu for instance) and need block those input devices for
exclusive use. But all this programs create a new virtual input device
and forward unused events to it, so that other programs (like
pbbuttonsd) will miss only some mouse events but not the whole device.
The synaptics X11 driver behave very uncooperative here.

This is a hardware issue and can't be solved or worked around by
software (except Apple has implemented some hardware registers allowing
to configure this behaviour, but I don't know about such registers.)

Re: USB trackpad: dim and wakeup

[Kristian B. <kb...@op...>]

The problem is with the event layer in the kernel. The synaptics driver
must grab the event device to make sure the events does not propagate
into /dev/input/mice. If it does not grab the event device, when X is
reading /dev/input/mice and you scroll using the synaptics driver, it
get the scrolling right, but it also get the mouse move.

So the solution is to patch the synaptic driver in such a way that is
does not grab the device. Configure your X to use /dev/input/eventX
instead of /dev/input/mice. The only problem left, is plugging a USB
mouse while X is running.

I'm planning on modifying the kernel event layer to have an event
aggregate like mice but configurable so you can tell it which event must
be aggregated together. The problem is to find the time to make it, but
it should'nt be to hard.

For the patch, see the from march 2006 named "pbbuttonsd not loading
every dev event".

USB trackpad: dim and wakeup

[Magnus R. <cmr...@fo...>]

Hello again,

while Johannes Berg hopefully tries to add the notap feature to the
appletouch driver, I send you 2 further problems with the USB trackpad,
which maybe could be solved by pbbuttons:

The trackpad does not reset the dim timer. So sometimes I have to press a
key to make the screen go bright again. This happens only when used with
the synaptics driver in X11. Without the synaptics driver the dim timer
works alright.

Just the other way round: Touching the trackpad or pressing the trackpad
button wakes the iBook from sleep. So if I grab the sleeping iBook with
closed lid right above the trackpad, the trackpad button is pressed by the
bending display and the iBook wakes up. I compared this with my G3 iBook
and there touching the trackpad does not cause it to wake up.

cu, Magnum

I have already corrected the number in your wiki some days ago ;-)

Why do you write "synaptics driver"? AFAIK there is no synaptics driver in
the kernel, only a synaptics driver for X11, which can be used
additionally to get some special features like scolling:

Are you sure your iBook has an USB trackpad? According my hardware list 
a PowerBook6,7 has a ADB Trackpad but this might be wrong.

If you have a USB Trackpad, the trackpad mode can't be set with pbbuttonsd.
I could implement it if the parameter could be set through /sys. What files
do you have in /sys/modules/usbhid/parameters/ ? Are there other paths
that might control the synaptics driver in sys?

notap on USB trackpad

[Magnus R. <cmr...@fo...>]

Hello Matthias &Co.,

on my iBook G4 12" 1,33GHz (mid 2005, PowerBook6,7) with USB trackpad it
seems to be not possible to switch the trackpad to notap mode.

In /etc/pbbuttonsd.conf I have:
  TPMode = notap

If I switch by hand, gtkpbbuttons and pbbcmd show the right configuration,
but tapping is still active:
  magnum@ibookg4 ~ $ pbbcmd config TPMODE 0
  magnum@ibookg4 ~ $ pbbcmd query TPMODE
  0

I use Gentoo Linux with pbbuttonsd 0.7.5 and kernel 2.6.16.

cu, Magnum

You should report this bug on the kernel mailing list or directly to
the maintainer of the ide kernel module. You should find his email
address in the documentation/maintainers files of the kernel source
code.

I'm sorry, but the wake up process is out of range of pbbuttons
capabilities.
