Description Evgeni Golov 2007-10-06 16:59:05 UTC
After installing 6.7.195, I got a kinda strange output on the screen of my Thinkpad X31 (Radeon Mobility M6 LY): the picture misses colors (it's not b/w, but  all colors are almost gray) and you can see the pixel-lines. As I don't know how to describe that better, I attach a photo of the screen.

6.7.194 worked fine for me, so I tried bisecting the problem, and found commit 597dffce9bdc200003d0be880235258386a0bdd7 (Alex Deucher, RADEON: final fix for RMX/LVDS) as the culprit.
master with only this one commit reverted gives me a good picture again.

please tell me, if you need any additional information.

regards
Evgeni

does changing line 105 of radeon_modes.c help:

-        new = xf86CVTMode(radeon_output->PanelXRes, radeon_output->PanelYRes, 60.0, TRUE, FALSE);
+        new = xf86CVTMode(radeon_output->PanelXRes, radeon_output->PanelYRes, 60.0, FALSE, FALSE);
Comment 3 Evgeni Golov 2007-10-07 02:56:54 UTC
it's line 106, but yeah, that helps.
thank you.
Comment 4 Alex Deucher 2007-10-07 16:43:47 UTC

Photo of my screen showing greys not displayed right

I am also seeing some color problems with 6.7.195.  Anything in the lighter grey area turns white.  Here is a photo of my monitor, a Dell 1905FP, of the freedesktop.org home page.  Notice the border around the fd.o logo is missing, also around the wiki nav bar.

Just for thoroughness, here is a screen capture showing what the color should look like.

Is this a regression from 6.7.194?  Is this a dual dvi card?  Please attach your xorg log and config.

I have not tried 6.7.194 yet.  I jumped from 6.6.x to 6.7.195.  I'll give it a shot.

> Is this a dual dvi card?

No, this is a Radeon Xpress 200 with a single analog output.

> Please attach your xorg log and config.

Will do.

I had the same problem with 6.7.194 as I did with 6.6.x.  My monitor goes into power save mode and the X server takes up 100% cpu.  I can renice it to a lower priority, but I can't kill it.  At least 6.7.195 gets the output correct.
