Description Thorsten Leemhuis 2006-09-17 08:22:13 UTC
Description of problem:
I have two systems with r300-based graphic chipsets. One is and i386 notebook with
01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon
9600 M10]
01:00.0 0300: 1002:4e50

the other one a x86_64 desktop machine with
02:00.0 VGA compatible controller: ATI Technologies Inc RV350 AP [Radeon 9600]
02:00.0 0300: 1002:4150

I'm running rawhide since two weeks on both machines (updated via yum from FC5).
I enabled dri and started gnome and everything worked fine. Later I enabled
compiz and it worked fine, too -- on both machines. I logged in and out some
times and it still worked.

But after a reboot the whole machines locks up after logging into gnome via gdm
in 75% of the cases *on the first log in*. Loggin in and out after the first log
in fails only in round about 15% of the cases. And the system only lock up in 15
% of the cases on the first login if I do this:
- start the system into runlevel 5 with dri enabled
- disable dri in xorg.conf from a console
- log into gdm; gnome starts without window decorations/window manager; wait
until everything has loaded and the buffers are filed
- enable dri in xorg.conf from console
- kill X with CTRL - ALT - BACKSPACE
- log in via GDM -> gnome starts with compiz and all the effects

Version-Release number of selected component (if applicable):
$ rpm -q compiz xorg-x11-drv-ati kernel mesa-libGL
otherwise rawhide up2date as of today

Additional info:
I know this isn't a proper bug report yet. But could somebody tell me where to
look further for the root of this problem? Or is this just another "r300 dri
isn't perfect yet" issues?

Found a better way to circumvent the problem in 85% of the cases -- start GNOME
with metacity enabled and enable compiz afterwards when all the buffers are
filled and the system is otherwise idle (the system still locks up in 15% of the
cases shortly after I hit "enable windows effects"). (Note: percentages only
wild guesses)
