Created attachment 372913 [details] dmesg Description of problem: My Dell Latitude D610 doesn't work with KMS. The display shows "fading psychedelic colors" when KMS kicks in, starting with a black display and slowly getting brighter and brighter in a non-digital way. Except for that the machine works OK. I guess the refresh of LCD display gets turned off when switching to graphics mode and that the crystals blocking twists thus slowly fades away. It works OK without KMS when the X ati driver sets the graphics mode. Version-Release number of selected component (if applicable): 2.6.31.6-145.fc12.i686.PAE - and "all" earlier versions
can you retry with 2.6.31.6-156 from koji I just added some fixes from upstream.
I just tried with 2.6.31.6-157.fc12.i686.PAE, and unfortunately I saw the same failing behaviour.
Created attachment 375618 [details] dmesg from 2.6.31.6-157.fc12.i686.PAE with failing KMS The machine booted fine to runlevel 3, the hd got quiet, and I could reboot with ctrl-alt-del
I noticed some radeon changes in kernel-PAE-2.6.31.6-161.fc12.i686, but still nu luck
Hi Mads, Could you attach the dmesg log with drm.debug=1 in the kernel command line? Thanks in advance -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Created attachment 382118 [details] dmesg - with drm.debug As requested ...
Created attachment 382119 [details] Xorg.0.log from working nomodeset session - just for reference
Thank you Mads. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
btw: Forgot to say that when I had booted with nomodeset and started X, removed nomodeset from grub.conf and used hibernate (suspend to disk) and resumed, then the kernel booted and started out in with KMS and this artifact, but when X was activated again it initialized video correctly, replacing the fading colors - probably because it remained in its nomodeset mode. So it seems like it is not that KMS destroys something - it just lacks something which X has.
Please try kernel from: http://koji.fedoraproject.org/koji/buildinfo?buildID=150696 I should have the fix for LVDS and thus KMS should work with. Report if it works.
Created attachment 383545 [details] dmesg - with drm.debug and working KMS Yes, thanks, kernel-PAE-2.6.32.3-24.fc12.i686 works fine! New dmesg attached, just in case someone wants to see _what_ it is that is working.
