I have Mesa 7.6, intel-2.9.0, xorg-server 1.7 installed on my amd64 system with kernel-126.96.36.199. Modesetting is enabled in kernel.
I am unable to start several programs, all of them require 3d:
supertuxkart -- unable to start, no warnings or errors whatsoever.
Alien Arena -- similar to supertuxkart, no warnings, no error, no start.
Warzone2100 -- the program hangs on start, shows black screen only, need to do kill -9
Configs for these games have been cleaned. They were working with previous versions of mesa and intel-drivers (except for warzone2100 which was working with mesa-7.6-devel). Other games, incl. 3d (tremulous, warsow, nexuiz etc.) run just fine.
Is the CPU busy at the point that the apps are hung? If so, please use sysprof to find where the CPU's spending its time.
I just tried supertuxkart, and it's working fine here.
Also, bisecting to find what commit of what component caused the failure would help.
No, the CPU is not busy.
Do you have amd64 as well? What are the versions you use?
My problem is that downgrading xorg-server from 1.7 is a major PITA, at least on Gentoo and older versions of intel driver don't compile with xorg-server-1.7
If the CPU isn't busy, then the next step is to gdb the app and backtrace to see where it's stopped (sample it periodically and see what it's doing -- stuck in one place?). Clear NEEDINFO when you've got some info there so I'll see the report again.
No, I'm not running an amd64 build, however we haven't had 64-bit issues for long enough I can't remember the last one, so I'm guessing that there's something else going on.
Could trace the problem to openal and pulseaudio which were updated at the same time as was xorg-server etc. Bug is invalid, sorry for wasting your time.
