Switch from OpenGL->XRender->OpenGL not possible

English Applications
1

Hi,
by playing around with KDE 4.1 I have switched from OpenGL to XRender by accident. When I try to switch back to OpenGL it says alwaysthat it is not possible, because of the Desptop effects. I have diabled nearly everything, but still not possible to switch back to OpenGL.
Does anybody has a idea where to look (e.g. config files) so I can revert the changes by hand?

Thanx
jürgen

Are the desktop effects working now?
What says:


cat /etc/X11/xorg.conf | grep Composite

?

3

no, the effects don’t work

radzuweit@earth:~> cat /etc/X11/xorg.conf | grep Composite
Option “Composite” “on”

So, if you go to Kicker -> Desktop -> Desktop Effects -> Advanced, you do not see an OpenGL option?

HI,
I see the option, but every time I try to switch back I get the error message. But where to look to get the current configuration?

Have you tried disabling, then re-enabling the desktop effects?

7

Yes I disable everything I could do, but still stucking with XRender and I can’t switch back to OpenGL >:(

I’m having the exact same problem with my Fedora 12 installation. However, I was wondering if you guys could help me, since I am also running kde. Here’s my xorg.conf:
