Ubuntu Feisty has v6.6.3 of the ati driver, and I can't change resolution when using it. For details, including a screenshot and my xorg.conf, see the bug report at https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/111674
Can you try the latest code from ati git or the ati 6.7.192 release?
I just tried the latest Ubuntu 7.10 beta (Tribe5) livecd and that worked fine. I don't think it has the 6.7.192 driver though. There are 6.7.192 packages for 7.04, so I'll try to test them this weekend, too.
In the Ubuntu 7.10 LiveDVD beta image, the 6.7.193 driver is present. I can change resolutions with that. However, none of the non-native widescreen resolutions are listed anymore. Even with custom modelines in my xorg.conf.
This should work, more or less, with ati git master.
Can you also attach your xorg config and log?
Created attachment 11842 [details] xorg.conf and Xorg.0.log
The guy handling the Ubuntu bug I have for this, Tormod Volden, built pacakges with "all the relevant changes from git upstream" so I tried those in the 7.10 beta livedvd. https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/111674 I'm attaching a tar file with my xorg.conf and Xorg.0.log here too.
Created attachment 11849 [details] changelog for my 6.7.194 package Just for the record, here's the changelog that lists which post-194 commits I included.

If you add the modes you want to the modes line in the display subsection of your config, it should add the modes, e.g., Modes "1680x1050" "1440x900" "1280x1024" "1152x864" "1024x768" "800x600" "640x480" You can also add modelines on the fly with: xrandr --newmode <modeline> xrandr --addmode <output> <new mode name>
I just tried changing the ModeLine specs in the Monitor section to take the refresh rate out of the name string, and made the corresponding changes in the Modes spec of the Display subsection of the Screen section. Those resolutions are still not listed in gnome-display-properties. Using the two xrandr commands (I guessed LVDS for the output in the --addmode command) succeeded in getting those resolutions listed in gnome-display-properties, and I can change to those resolutions once they are listed. The xrandr commands also work on the Ubuntu 7.10 LiveDVD without Tormod's 6.7.194 package.
Bugzilla Upgrade Mass Bug Change NEEDSINFO state was removed in Bugzilla 3.x, reopening any bugs previously listed as NEEDSINFO. - benjsc fd.o Wrangler
The 8.01 catalyst driver from ati.com detects the non-native widescreen resolutions, and supports custom modelines, so I'm using that now.
