AMD Catalyst 8.443.1 & 1280x768 Widescreen Kubuntu

[Tonren]

Hi there, I recently manually upgraded to fglrx 4.443.1 so I could use AIGLX with compiz-fusion (which is working great), but my laptop is a 1280x768 widescreen, and the Display Settings part of the Catalyst Control Center won't let me select that as a resolution--it's stuck at 1024x768. It lets me set my "digital display" to 1280x768, and I'm assuming it's getting that from xorg.conf, but I don't know where this 1024x768 setting is coming from, nor how to change it. If I select "Scale image", it just distends my 1024x768 display to fit 1280 wide.

By the way, this is my xorg.conf:

So, can anyone help me out?

Thanks!

It's a bug on the latest driver release. My lappy also has a 1280x768 native resolution, but the driver only lets me set 1024x768. Either wait for the next release or rollback to the 7.11 drivers which also support AIGLX.
