See: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-driver-ati/+bug/152312 Following an upgrade from Feisty on Kubuntu, the display now appears too washed out such that "greyed-out" text is invisible in most colour schemes (the text in this window is only just visible!). No amount of adjustment of the monitor controls will bring the display back to it's former state under Feisty. Altering the gamma setting in /etc/X11/x.org.conf or via xgamma to a value of about 0.4 - 0.5 will improve matters slightly but this was not required in previous releases. I installed the "ubuntu-desktop" meta package and got the same results under GDM/Gnome desktop.

This looks similar to my problem [1] with washed-out colours on the external VGA monitor (but the laptop panel is fine). Can someone confirm if it's likely to be the same bug? [1] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=440174

Created attachment 12110 [details] [review] xorg log Attached is Xorg.0.log Note this was created using: xserver-xorg-video-ati_6.7.195~git20071017tv the "upstream update" from: https://wiki.ubuntu.com/XorgOnTheEdge http://ppa.launchpad.net/tormodvolden/ubuntu/pool/main/x/xserver-xorg-video-ati/ Which made no difference at all to the washed out appearance compared to the current standard gutsy deb.
Created attachment 12146 [details] Xorg log file I have the same problem with ATI Radeon 7500 and two Dell E176FP.
Created attachment 12148 [details] Xorg log of the affected X session I experience problems that I would describe in the same way. That's with a ATI Technologies Inc RC410 [Radeon Xpress 200] over an analog CRT link. The same monitor used to work fine over a DVI link with a radeon 9250, but unfortunately didn't try the CRT link at the time. The Xpress is lacking a DVI output connector.
Does switching to another VT and back again to X fix it? How about blanking the monitors with dpms?
Switching to another VT and back does not help for me.

Are you sure this is a duplicate? Bug 1082 is much older, but this one appeared only recently, so I don't think this is the same issue. To recap, (from bug 12912), I was able to fix my problem to revert to an older driver version.

heads-up: I tracked down the regression to somewhere between ati-6.6.192 and ati-6.6.192

We'll need to see a full dump of regs (./radeontool regdump '*'). grab the latest version of radeontool here: http://gitweb.freedesktop.org/?p=users/airlied/radeontool.git;a=summary *** This bug has been marked as a duplicate of bug 1082 ***

yes, sorry for the typo, I meant .193. I 'git bisect' it, and tracked it down to 104105fee5c3945d3f210e6a4cb73ab492c61543.

please try again with ati git master. I think I've fixed this.
(In reply to comment #18) > please try again with ati git master. I think I've fixed this. > I have applied the latest patch from git and this works for me. The screen is now darker but this is far more reasonable.
(In reply to comment #18) > please try again with ati git master. I think I've fixed this. Works great with `git diff a94123f..49055d8` (your MT and BGADJ/DACADJ fixes in two commits) applied on top of 6.7.196. Brightness is fine too, just as expected to my current brightness setting in LCD onscreen settings. So basically as good picture as with 6.6.3 (which I finally got to work two days ago here for a bearable picture), just with all the other improvements (not requiring a custom modeline for starters). So, many thanks! /me awaits a release and considers poking dberkholz to let him include this in gentoo tree meanwhile
works fine for me also, thanks alex :)
