Starting KDE 4 effects gives me a black screen!

leandroribeiro · June 21, 2008, 10:06am

I there!

I used 10.3 for a long time and loved it. Now I’m trying to get openSuse 11.0 running. Everything went smooth, except for one thing: KDE4 effects.

The first time I turned on KDE4 effects, without fglrx ATI drivers, they worked, but very clumbsy. FPS was very, VERY, low! So I turned off KDE 4 effects and installed the ATI drivers from ATI openSuse repo. When I then turned effects on, my screen whent black and I could only see the mouse pointer.

I tried Kubuntu before openSuse 11 came out and effects worked fine, although I was using KDE 4.1.

Any ideas as why this is happening?

Thanks in advance,
Leandro

where is the composite extension, u don’t have that enabled?

leandroribeiro · June 21, 2008, 10:26am

I have no idea

The box in sax2 is checked. I recall having to do something about that when I first tried linux (couple of years ago), but ever since Ubuntu 7.10 that I don’t mess around much with config files.

How do I do this and why isn’t activated by default?

snakeeyes · June 21, 2008, 10:35am

I have no idea why it isn’t on by default though it should be…

type in konsole:

kdesu kwrite /etc/X11/xorg.conf

paste this at the end:

Section “Extensions”
Option “Composite” “Enable”
EndSection

If the composite extension alone doesn’t work then trying putting these in the screen section right below “DefaultDepth 24”

Option         "RenderAccel" "True"
Option         "AddARGBGLXVisuals" "True"

Please note that whenever u modify xorg.conf, u need to log out and press “ctrl”+“alt”+backspace to restart xserver for changes to take effect.

Tell me how it goes then.

leandroribeiro · June 21, 2008, 10:50am

Thanks!

I was already trying to paste something similar (Option “Composite” “1”) that I read in another place, but I didn’t knew how to edit xorg.conf with admin password (sudo kwrite wasn’t working :o)

Anyway, now all is smooth and working

Thanks a bunch!

no problem
