Can't run KDE with OpenGL using radeon driver

Hi,

I'm running KDE on a ThinkPad T400 with an ATI Radeon HD3470 card using the radeon driver. I've got the desktop running with desktop effects using XRender, but when I try switching to OpenGL I get a pop-up saying...

"Failed to activate desktop effects using the given configuration options."

I've tried tweaking the OpenGL options in KDE and various driver options in xorg.conf but it fails every time. glxinfo reports that direct rendering is working and glxgears runs at around 200fps.

Here's my xorg.conf:

The desktop looks great but I'd love to get it working with OpenGL. Any suggestions greatly appreciated.

Re: Can't run KDE with OpenGL using radeon driver

Unfortunatelly, this driver doesn't support opengl with your card. Radeonhd driver doesn't support either. You can only use desktop effects with XRender, but not all and some of them might be choppy.

The only solution for you is installing catalyst drivers (not recommended, hanged my system several times per day) or turning off desktop effects (recommended). In 2 months 2.6.30 kernel should be out with extra features and tweaks, allowing to use EXA with radeon drivers, so XRender performance should fly. Unfortunatelly I don't have any information about OpenGL support with open source radeon drivers.

I moved from nvidia to ati, after nvidia's problem with kde performance, but ati is not better.

Re: Can't run KDE with OpenGL using radeon driver

Thanks for your help. At least I know I can stop messing around with it for now. To be honest, the desktop behaves perfectly well using XRender for the only effect I'm interested in (translucency); I just wanted to get as much performance as possible out of the hardware.

I tried the catalyst driver and like you I could never get a properly stable desktop out of it. However, it did such nasty things to the screen that I stopped trying to get it working pretty quickly.

So if anyone out there has got catalyst working nicely on a T400, feel free to post your xorg.conf below.
