pochopil som spravne ak mam odinštalovať nepotrebny software?

I have same GPU as your and all is working fine in Jaunty with fglrx.
How I resolved:
Reinstalled a clean copy of Jaunty.
After applying updates, I opened Synaptic and removed all xserver-xorg-* useless packages (related to other VGA). Here's the list:
xserver-xorg-video-all
xserver-xorg-video-apm
xserver-xorg-video-chips
xserver-xorg-video-cirrus
xserver-xorg-video-intel
xserver-xorg-video-mga
xserver-xorg-video-neomagic
xserver-xorg-video-nv
xserver-xorg-video-openchrome
xserver-xorg-video-rendition
xserver-xorg-video-s3
xserver-xorg-video-s3virge
xserver-xorg-video-savage
xserver-xorg-video-siliconmotion
xserver-xorg-video-sis
xserver-xorg-video-sisusb
xserver-xorg-video-tdfx
xserver-xorg-video-trident
xserver-xorg-video-tseng
xserver-xorg-video-voodoo
After, I installed the xorg-driver-fglrx package and all dependencies, via Synaptic.
Next step, opened a terminal and typed:
sudo aticonfig --initial -f
Finally, I crossed my fingers and reboot. And I'm still here
Compiz works fine and also Google Earth 5 from Medibuntu repository runs smooth (but with compiz or minimal effects enabled the earth start to flash and is unusuable).
a čo to potom ? After, I installed the xorg-driver-fglrx package
