Comment 382 for bug 252094

Hi there,

I've the same problems with kubuntu and jaunty on a minimac with 945G. After googling around I found different proposals. To get some solutions to work I opened a file with 'sudo kate' from konsole. Kate was starting but I got an error-message like this 'Could not start ksmserver. Check your installation.'. After clicking OK to that message kdm (xorg?) is doing a restart. After logging in back everything is going smooth. glxgears makes 1100 fps (former 400fps) and all the dasktop effects and 3d-games are working well. If I restart the machine I've again the slow and sluggish desktop. I reproduced this behaviour serveral times. I didn't touch any configuration files.
