http://bugs.freedesktop.org/show_bug.cgi?id=27206

           Summary: Blurred screen with latest drm-next-radeon and KMS
           Product: DRI
           Version: DRI CVS
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.sourceforge.net
        ReportedBy: ke4unq@bloatware.de

Login screen garbled

Right after the initrd is loaded and console switches to KMS native resolution,
the screen gets garbled. There are vertical blurs approximately every 1 cm of
horizontal screen space. These blurs repeat regions of previous screen extate
so the visible screen is only 2/3 of its true full size. Difficult to explain,
therefore attached screenshots with a camera.

Sometimes, in irregular intervals the screen "resettles and shows its true
size. This is both with dypm enabled and disabled. Booting without KMS is fine,
no garbage on scree, both on console and under X.

resolution and no garbling:

What kernel are you using?  Can you attach your dmesg?

Plus all patches from:


http://people.freedesktop.org/~agd5f/pm2/

which could all be applied cleanly.

Which ones didn't apply?  I wouldn't recommend that patch set unless you apply
all of them (they apply to drm-radeon-testing).  Do you still have problems
without those patches applied?

I pulled a clean, full tree from airlied's drm-next-radeon tree and applied all
the 30 patches from your repo and that's what doesn't work.

However, there is a slight chance that this is actually hardware related. I
have had the LCD inverter changed last week, because of a backlight failure and
I have now found out that it was a temperature related problem (notebook
staying in a rather cool room overnight), which spontaneously disappears when
the laptop gets back to room temperature. It likely is a problem either with
the GPU itself or the video RAM and I expect to have it replaced either
tomorrow or day after.

I will report back as soon as I am sure that my hardware is running flawlessly.
