If you are not using Karmic, nor the Jaunty kernel in the xorg-edgers PPA, and did not set any options as explained on https://wiki.ubuntu.com/X/KernelModeSetting , you are probably not using KMS. You would see display detection and "mode setting" messages in dmesg if you are running KMS.
Do you have the old packages, for instance in /var/cache/apt/archives, please verify which version works and not. -- xrandr: Configure crtc 0 invalid time https://bugs.launchpad.net/bugs/394490 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
