Bug Description

Binary package hint: xserver-xorg-video-ati

While kernel modesetting is enabled, it is not possible to select resolutions lower than 1024x768 in gnome-display-properties sucessfully. Attempts to do so result in a white screen until the original resolution is restored. Does not happen when KMS is disabled. Video card is ATI Mobility Radeon X700 and OS version is Ubuntu 10.04 LTS.

Matt, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
