Hi Yes that is the thing. I have allready tried to install the driver u talk about for my ati. I found a guide and followed it. Make shure it was the right version and for lnux not windows too..... However.... I tried this 2 times but everytime i tried I got big problems right after installing the driver. First I got small graphics problem like i desribed but then I was locked out of the ubuntu system and I could not log back on again right after I installed this very driver. So no it does not work installing it like u describe. So is there another way to install it ? Linux is the most stable os ever. I have not had any problems running everything inclubding running windows aps on wine.... The only place in linux I have problems is with this. So everything points to this very driver...... Now the driver is disabled and everything works and I do not get graphics problems or freezing or stuttering. Is there maybe a patch for this driver or for linux to work better with it ?
