I noticed that to have 3D accelerated, you had to add monitor section for each output try modifying xorg.conf as follow :
in the device section add : Option "monitor-VGA1" "vga" Option "monitor-LVDS1" "lvds" EndSection section add : and 2 monitor sections : Section "Monitor" Identifier "vga" EndSection Section "Monitor" Identifier "lvds" Option "Ignore" "true" EndSection -- Slow rendering opengl and CPU 100% (intel gma945) https://bugs.launchpad.net/bugs/565163 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
