x1250: high guys, I wonder if anyone can shed some light. I'm trying to play Tremulous, which is based on Q3 engine, and it works ok in terms of performance, but the brightness slider ingame doesn't work, and the game looks quite "opaque", kinda gray, like if it lacks some contrast and/or brightness. I wonder if this is a known issue?
x1250: I'm using xf86-video-radeonhd-git
x1250: from today
udovdh: does it need 3d?
x1250: yes, opengl
udovdh: did you check out the latest mesa?
udovdh: it might help
x1250: ok, i'll try with mesa from git. Now I'm using 7.7
udovdh: OpenGL version string: 1.2 Mesa 7.8-devel
udovdh: that is mesa head
udovdh: howtoish: http://turqee.tumblr.com/post/230394871/dri2-for-radeon-r600-700-chipsets-on-ubuntu-9-10
udovdh: userspace part
sbasuita: Hi, I have an RV610 (hd 2400 pro), for which i think 3d is supported on radeonhd. But, in Xorg.log I see "(**) RADEONHD(0): Selected EXA 2D acceleration.". How can I enable 3D?
agd5f: sbasuita: you need kernel 2.6.32 and mesa 7.6.1 or newer
sbasuita_: agd5f, I have "Linux ssb-desktop 2.6.32-020632-generic #020632 SMP Thu Dec 3 10:09:58 UTC 2009 x86_64 GNU/Linux" and libgl1-mesa-glx 7.8.0~git20100130.996fd614-0ubuntu0sarvatt~karmic
agd5f: sbasuita_: should be all set then
sbasuita: agd5f, what do i need in xorg.conf?
agd5f: sbasuita: nothing special
adamk: sbasuita: What makes you think it isn't working now?
agd5f: sbasuita: run glxinfo
sbasuita: agd5f, what am i looking for in there?
agd5f: sbasuita: look at the renderer string
sbasuita: agd5f, OpenGL renderer string: Mesa DRI R600 (RV610 94C3) 20090101 TCL
agd5f: sbasuita: you have 3d accel then
sbasuita: poor performance then :(
agd5f: sbasuita: what are you trying to run?
sbasuita: agd5f, well, warsow was unusably slow (like 1 fps). Nexuiz is playable on low settings but still not smooth.
adamk: sbasuita: There are certain items (namely accelerated blit) that might give better 3D performance, but they require using KMS, which radeonhd doesn't support. Radeon, however, does. That *might* improve your performance in those two games.
