[RS485] X Server ati/radeon driver resolution issue

[Barret Ruttan]

Binary package hint: xserver-xorg-video-ati

Not sure if this is a bug, per se, but here goes.

If I switch to a resolution with a 4:3 aspect ratio(800 x 600, 640 x 480) I see a blank screen. However, this is not the case if I switch to 1024 x 768, which also uses a 4:3 aspect ratio:

lspci -nn | grep VGA

Barret Ruttan, 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.
