Option "AGPMode" "4" seems to have solved it for me.And me to !!! Yipee. The only issue I have now is that if I don't unplug my usb stuff before a sleep I get a kernel panic, and if I don't have anything plugged in when I resume my usb ports don't work. (I have to do a cycle sleep with the usb devices plugged in in order to get them to work). I know it is just a case of modifying some scripts, but how and what do I have to do ??? Michael Hunt
Why don't you try the the gentoo fix I posted on the ubuntu forum. Tell the forum how you it works out and clearly how you did it.
