Package: xorg
Followup-For: Bug #319689
Hi
I have been experiencing the same symptoms on my Pegasos II with recent
kernels. Symptoms are as follows:
- When gdm starts up, X hogs the CPU and the screen remains blank or out
of sync range. It's impossible to switch to VTs, have to ssh into the
box to reboot it.
- disabling *either* the glx or dri module fixes the issue
Kernels tested:
('-ck' are con kolivas', see http://members.optusnet.com.au/ckolivas/kernel/)
- Debian 2.6.15-1: works
- 2.6.15-ck1: works
- 2.6.15-ck3: might expose the bug sometimes (*)
- 2.6.15-ck4: will almost never work (*)
- 2.6.16 vanilla: doesn't work
- 2.6.16-ck1: doesn't work
- 2.6.16-ck5: doesn't work
Some more comments: the "(*)" above means that the bug will not always
show up with these kernels, that is, it is possible to have a working X
without tweaking the configuration file.
Investigating this a bit more, it seems to me that this bug is somewhat
related to the initialization sequence of the gfx card: depending on the
state it was left before the reboot, screen symptoms won't be exactly
the same (either totally blank, monitor going to suspend mode; or
garbage, monitor showing "out of sync range").
I couldn't tell a difference between cold and hot reboots though.
I also noticed that for the two "(*)" cases, fiddling with "UseFBDev"
setting would have an impact sometimes.
Now some technical data:
