Problem with direct rendering in KDE 3.5 using ATI X700
 

Hi all,

I recently installed kde 3.5 from source on slackware on my laptop. I have managed to get direct rendering partly working. I run glxgears and get ~4000 FPS and glxinfo says direct rendering:yes. However, the opengl screen savers run extremely slowly (~1/2 FPS) as if they arent using the graphics card at all. I do a lot of programming in OpenGL so I need to try and get this working.

Firstly, the ATI X700 is PCI Express, so should I include agpgart in the kernel? I currently have that and ATI chipset support (I have an ATI chipset). I have NOT included Direct Rendering Manager (I included it previously as a module but it didnt fix the problem).

The file /var/log/Xorg.0.log says it's loading module 'drm' AND 'fglrxdrm' which may be the problem. Module fglrxdrm tries to load /dev/dri/cardX where X = 0..255 even though only /dev/dri/card0 exists ( so i get pages of error messages).

Anyway at the end it looks like drm gets set up correctly by the fglrx driver but still the screen savers dont render using the graphics card.

Anyone have any ideas what I am doing wrong?
