General suggestions to improve X rendering speed?

mattdev121 · 04-19-2005, 09:06 AM

I've been using linux for almost two years now so i'm quite comfortable with bash, compiling source, new kernels, patching source, etc.

I am in slackware 10.1 with kde 3.4 and linux 2.6.11.7.

This is quite a vague question but I was wondering what steps I could take to get 3d games and OpenGL programs to improve thier speed, as I have a p4 @ 2.4ghz and a radeon 7500 and games like zsnes run with crippled frame rates that run 100 times as fast on a windows machine.

I (think) I have the proper kernel modules for my video card and dmesg|grep radeon shows the modules correctly loaded, as well as having enabled dri, dbe, glx and radeon_dri in my xorg.conf

Are there any other steps I can take to improve both 3d games like armagetron and 2d opengl games like zsnes to be playable?

Thanks for the help - If anybody wants a gmail invite just tell me and i'll be glad to give you one (or 50 :P )

you have direct rendering on?

(look at "glxinfo")

mattdev121 · 04-19-2005, 09:28 AM

name of display: :0.0
display: :0 screen: 0
direct rendering: No

hmmmm

I thought the DRI module would load that.

How do I turn it on?

I checked into the DRM problem and I have the proper radeon DRM drivers compiled into the kernel and dmesg|grep gave:

[drm] Initialized drm 1.0.0 20040925
[drm] Initialized radeon 1.14.0 20050125 on minor 0: ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500]

I have loaded the "DRI" module in xorg.conf and still glxinfo gived direct rendering: No

Is there anything else I need to do?

Check /var/log/Xorg.0.log

Usually this hapens in 2.6 series because to get agp working you need to load agpgart modules *after* the specific agp module for your motherboard (ie: via-agp).

i just prefer to compile it all in, after all, in a monolithic kernel, the only advantage of modules, is people can release binary drivers for your kernel.

when you have agpgart and the DRM in your kernel, (assuming you did a xorgconf to configure X for your card), edit the xorg.conf file, and uncomment the DRI and GLX lines.

Key step for me was make sure this is in your xorg.conf somewhere:

Code:

Section "DRI"
   Mode 0666
EndSection

If that doesn't work, troubleshooting can be found here:
