ati amd64 strange opengl errors

eskay187 · n00b Joined: 30 Jan 2005 Posts: 10 Location: Austria

i am using gentoo 2004.3, kernel 2.6.9 amd64, newest xorg and the newest ati-drivers.
i finally got my ati-drivers working, the module is loaded correctly, x starts fine, fglrxinfo shows im using the ati driver. glxinfo | rendering reports direct rendering works. everything fine so far.

but fglrx-gears shows about 800 frames with FULLl processor usage, glxgears too.
for further tests i emerged quake3. after trying to start it it reported that i was using
mesa opengl - very funny. i figured that it was using the wrong libgl.so.1 and manually changed it in the config file to libglib-1.2.so.0 which worked better.

it seems to my that most of the gl-applications dont use the correct opengl library,
and opengl-update ati doesnt seem to solve this problem. in kde i cant activate opengl screensavers, the gl gears seem to run over processor ... and still my system tells me that the ati opengl is activated.

thanks for your help

'Lo.

I have exactly the same problem (and almost same hw config) as you.

I would really appreciate any help. I get almost 3000 fps in glxgears, though.

Games tested: tuxracer, race, quake3.

So it's not only me and my n00bedness to blame here, heh ... Hope this will be figured out, soon.

Try:
# opengl-update ati

(# means as root)
Should set your opengl rendering system to use the ati-drivers and not mesa.

Good luck,
Frank

There have apparently been a lot of problems for AMD64 users in getting games to use the correct OpenGL libraries. I think if you search the AMD64 forum here you should find one or more solutions quite easily.

does anyone know what "default" opengl libary is used by applications ? because it seems to me that the standart libraries ary simply links to the "to-be-used" librarys like mesa||ati. if i change the links manually to the ati-file, the problem could be solved this way...

thanks

Wohaa, thanks to that thread I got tuxracer && race working nicely in OpenGL.

Quake3 still gives problems (it does start up, ati ogl used etc) - the game still jams up with VERY slow rendering or something. Ctrl+Alt+Backspace helps but other than that cannot get back to desktop.

Might be installation/config related stuff though.

Or could it still be about that q3 is a 32-bit app and run in emulation mode as in tuxracer and race are native AMD64?

Edit-Start: Did a fresh q3 installation (new dirs + pak0.pk3 from old q3 + emerge quake3 to that dir etc), still same problem.

My q3 startup script uses the LIBGL_DRIVERS (and whatnot) export to /emul directory which contains the fglrx_dri.so ... if I don't do that Q3 will complain about software rendering.
Edit-End
