 Posted: Thu Sep 23, 2004 1:36 am Post subject: glx wierdness - possible lib issue? |
 |
|
hi all,
i'm running a 2.6.8-ck7 kernel, nvidia 6111 drivers, have an
athlon 2000xp with a 128Mb nvidia gf 4600ti. i have
sidebanding and fastwrites enables and all is good in
/proc/drivers/nvidia/agp/.... and in my bios.
i recently reinstalled my system with nptl. just after setting
the machine up, i started X and ran glxgears to make sure
the nvidia drivers were working correctly. i wasn't surprised
to see 4300 fps. i then installed/reinstalled a few things,
changed flags and then emerged system to make sure
everything was compiled with the new flags.
here is the wierdness-- glxgears gives me about 200 fps
now. it isn't however as bad as it seems- i can run
unreal-tournament at 1600x1200x24 with high detail and
high quality everything at over 120fps. i can maintain well
over 30fps with nvidia-settings cranking up the antialiasing
and image quality... obviously glxgears has gotten
confused, but i don't know how, and am worried that such
an issue may cause other problems.
here is some info i thought might be useful in diagnosing:
| Code: | # ldd /usr/X11R6/bin/glxgears

does that output look right to everyone? thanks for any insight, i'm dumbfounded. |

After you emerge'ed system, did you opengl-update again? You may need to change over to the nVidia interface again.

yes, i did. thanks, but no dice.
it changes nothing anyway- xorg-x11 and nvidia's drivers give comparable performance. actually i noticed that under the current circumstances xorg's was giving solid 197fps while nvidia's were yielding 195-199. the libraries pointed to above in my earlier post show that libGL was loaded from /usr/lib/opengl/nvidia, so when i last ran the test the nvidia interface was in use. |

Then, the only solution that i can think of is that perhaps under the old software and flags, glxgears simply reported a wrong FPS. You said that you didn't have any problems wth other games, right?
Odd indeed...

well, yeah, that's possible. but looking in other threads at reported glxgears frame rates, i see other users reporting anywhere from 1500 to 6000. 4300 is just what i'd guess this card should do. when glxgears reports 120fps, it's a very bad sign - it's abysmal. the fact that i can get 120fps at high res and high quality in any game is bizarre when compared to that fact.
i'm just curious if anyone is aware of a library linking problem that would cause this. |

Had some weird libvisual plugin problems and stumbled across something in a forum. I'll bet if you look at
| Code: | | ls -l /usr/lib/opengl/nvidia/lib/libnvidia-tls.so |
and
| Code: | | ls -l /usr/lib/opengl/nvidia/lib/tls/libnvidia-tls.so |
you'll find they differ in size. Also, note that glxgears shows linked against the one in the tls directory.
Perhaps emerging the drivers again or packages related to tls would fix it.. I took the brute force approach and replaced the one in the tls directory with the one in the lib directory. The plugins now work properly. btw, the error message I was getting was
| Code: | | libnvidia-tls.so.1: cannot handle TLS data |
Good luck |
