I haven't tried building libGL from Mesa CVS yet. But AFAIK it shouldn't make a big difference. I haven't been following that development so I can only speculate about the exact differences. > > but I have next problem: X server locked after a few minutes playing in > quake2 ;( My computer do not react on mouse or keyboard activity... but > this is not bus lock --- mplayer is contining playing music and I can login > on the computer through SSH. > > it is the head of top output: > > top - 11:02:53 up 19:53, 8 users, load average: 1.22, 0.57, 0.25 > Tasks: 59 total, 3 running, 54 sleeping, 0 stopped, 2 zombie > Cpu(s): 0.3% us, 99.7% sy, 0.0% ni, 0.0% id, 0.0% wa, 0.0% hi, 0.0% si > Mem: 255232k total, 185004k used, 70228k free, 29812k buffers > Swap: 0k total, 0k used, 0k free, 117208k cached > > PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND > > 1444 root 25 0 148m 5832 3332 R 99.3 2.3 1:59.36 X > > 1423 dima 15 0 2628 1084 908 S 0.7 0.4 0:01.30 esd > > 1487 dima 16 0 1864 964 764 R 0.3 0.4 0:00.14 top > > > As I can see --- all cpu power eaten by X server, but I cant kill it :( > even with help -9 or -11 signal 8o probably because the proces is in system > (kernel) mode... Sounds like a graphics engine lockup. Some process keeps holding the lock waiting for the engine to become available, which it never does because it's locked up. In the mean while X tries to grab the lock and fails. So it keeps retrying, eating 100% CPU. Just a theory though. There have been reports about instabilities with r200-based cards. It was introduced by some driver change last year. But AFAIK noone got around to tracking it down. :-/ > > what I can do? and how I can debug the problem? Try to find a version in CVS that works and then narrow it down to one specific commit that introduced the problem. This will be time consuming and not very exciting though. > > PS: I have more problems: If I exit from quake before X locked --- the > mouse locked (or grabbed ??)

Why this can be? Probably quake2 or the 3D driver segfaults before the mouse grab and graphics mode can be restored, possibly in r200DestroyContext. If it's crashing in the graphics driver this should be fairly easy to track down. Enable core dumps (ulimit -c unlimited) and analyze the core dump with gdb to see where it crashed (gdb -c core `which quake2`). (Caution, quake2 may be a shell script. You must point gdb the actual executable instead.) In gdb use the "bt" command to see a call stack trace. "up" and "down" jump between stack frames. Use "print" to inspect variables. (This is just general advise. I don't have any r200 hardware myself ATM.) > > -- > Dimitry HTH, Felix -- | Felix KÃhling <[EMAIL PROTECTED]> http://fxk.de.vu | | PGP Fingerprint: 6A3C 9566 5B30 DDED 73C3 B152 151C 5CC1 D888 E595 | ------------------------------------------------------- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?
