fglrx in ltsp clients

[David Van Assche]

Hi,
   I've been waiting for the new ATI drivers for many months to finally get
X working properly on my thin clients (all running ati X1450 radeon.)
Finally they've come out and I've tried following this here:
http://www.howforge.com/how-setup-fglrx-8-42-3-and-compiz-ubuntu-gutsy

So... I go into the /opt/ltsp/i386 chroot and follow instructions, but being
specific about the kernel, since I have a 64bit kernel on the server, but 32
bit clients...:

#sudo module-assistant prepare -- want to use i386 kernel, not current kernel
sudo module-assistant update
sudo module-assistant build -k /path/to/kernel -f fglrx
sudo module-assistant install -k /path/to/kernel fglrx

Some of these steps give errors about not finding the kernel image...
however, all the necessary files for building seem there, so maybe
ltsp-update-image will do this for me... If I go into an actual client and
do the steps, it works fine... So how should I be doing this from the
chroot?

Maybe I've gone wrong here... not sure... but even so, it does look like its
trying to load the new fglrx driver.

So... Then I put in my own /etc/xorg.conf that looks like so:

I add XF86CONFIG_FILE=/etc/myxorg.conf to
/var/lib/tftpboot/ltsp/i386/lts.conf
and just in case XCOLOR_DEPTH=16 (I've tried taking this out too)

I also get a failed module: binfmt-464c, which I've blacklisted... and now
get no more errors...

Anyway... start up client and X fails:

"(II) ATI Proprietary Linux Driver Version Identifier:8.42.3
(II) ATI Proprietary Linux Driver Release Identifier:
UNSUPPORTED-8.423.2

(II) ATI Proprietary Linux Driver Build Date: Oct 19 2007 16:13:26

Backtrace:
0: Xorg(xf86SigHandler+0x81) [0x80c9581]
1: [0xffffe420]

7: Xorg(FontFileCompleteXLFD+0x1e1) [0x8076241]"

I've tried logging into the client and checking xorg.conf, but of course,
that no longer exists  in gutsy :-)

Any help to get this working is much appreciated... I've been banging my
head against a brick wall for a while now...
