** Description changed: I'm using Kubuntu 9.04 (RC1) The problem might be in Xorg-ati, xorg-server or maybe kwin. When I switch on 'Desktopeffects' in 'Systemsettings>Desktp>Desktop effects' I get all the nice eyecandy imediatelly and I'm able to work for a while (a couple of minutes). But after a random period of time the whole system freezes - usually the screen gets black and the machine dosn't react on either input - neither the keyboard(ctrl+alt+del) nor the powerbutton on the case causes any reaction. The only possibility is to 'pull the plug' (press 'power'-butten for more than 5 seconds). At rebooting i often have trouble afterwards and have to use the recovery-mode to repair filesystem. At some occurancies, I can see the desktop after the crash (but not touch anything) instead of the black screen but apart from that the situation is the same. When using the OpenGL-setting 'common RAM' only the X-Server crashed and I was dropped to KDM.
