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 Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
