Resolution issue: default screen resolution impossible to get with ATI Radeon Xpress (regression)

Here's my xorg.conf file, at least the one that gets me an acceptable 1280x1024 to work on, not a widescreen 1280x960 (or the unsupported 1600x1200).

Are you using fglrx, the proprietary driver, instead of xserver-xorg-video-ati?

Yes, I had tried a few changes but fglrx is what gives me the most stable solution.
Sorry if the bug is not filed under the correct category.

Cleanly downgraded from an optimistic 8.40+ ATI driver to 8.37.6
No change. The best I can get is still 1280x1024, with proprietary fglrx (activating the ATI restricted driver seems to help).
The windows Samsung .inf driver has been installed since PnP wasn't ok with gutsy, yet the native 1400x1050 resolution doesn't appear in the 'Screen & Resolution' menu/screen reference, jumping from 1280 to 1600 (not supported)!
Forcing 1400 crashes X window.

Here's the xorg.conf file generated after clean ATI driver reinstall (although I switched from comand line the catalyst install manager at some point) and chosing PnP screen with 1400 (loads 1280).
Don't know where the 1600x1200 resolution comes from...

I eventually came back to the pre-upgrade xorg.conf file. My 1400x1050 screen resolution is now fine (although refresh freq could go to 75Hz).
Proprietary ATI drivers still enabled.

I hope this will help to mend the ugly regression that came in with the Gutsy release.

Hi lfraisse,

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with the latest development release of Ubuntu? (ISOs are available from cdimage.ubuntu.com)

If it remains an issue, could you also attach a new /var/log/Xorg.0.log?
Thanks in advance.

The output of lspci -vvnn would also be worth having.

As of Intrepid (8.10), we have a dedicated package 'fglrx-installer' for fglrx bugs, which now includes a process for upstreaming bugs to AMD.

  http://bugs.launchpad.net/ubuntu/+source/fglrx-installer

To transition your bug into the new fglrx-package, we need your help. Please do the following:

 a. Verify the bug occurs in Intrepid.
     (Intrepid ISOs: http://cdimage.ubuntu.com)
 b. If you haven't already, please include in the bug:
     * Your /var/log/Xorg.0.log
     * The output of `lspci -vvnn`
     * Steps to reproduce the issue
 c. Click 'Also affects distribution'
 d. Set 'Source Package Name' to 'fglrx-installer'
 e. Click Continue

Thank you. This will assist us in reviewing and upstreaming your fglrx bug, as appropriate.

[We'll expire the fglrx bugs in l-r-m-* in a month or so.]

My hardware configuration has changed (and I can't smoothly remove the new
Nvidia card from my tiny barebone) so I can't try and replicate the bug
under Intrepid.
Sorry,
LF

OK, it would probably be best to close this since you can't reproduce it any more due to your new hardware. Thanks for the report all the same.
