           Summary: rv515 (Mobility x1400) Display corruption after some
                    time
           Product: DRI
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: gtdev@spearhead.de

lspci output (graphics only)

After some uptime (upwards of an hour so far), I get different kinds of display
corruption on a laptop with a Radeon x1400.

Currently, I'm looking at a somewhat grainy picture which looks like a badly
dithered low-colour version of the screen content. There are noticeable
vertical stripes, and the whole image is shimmering. The system is working fine
otherwise.

In an earlier instance, I had a pulsating green gradient covering the bottom of
the screen. In addition, screen response was slow, like the proper content was
only updating evers second or so.

The effect does not show in screenshots.

This is on a Debian-built 2.6.34 686 kernel, running X.org 1.7.7 and the
"radeon" driver 6.13.0, libdrm2 2.4.21 from Debian packages.

I'm attaching lspci output for the card, as well as dmesg and the Xorg.log from
the currently "broken" running system.

It's still there in the 2.6.35 kernel.

I noticed the following messages in dmesg when waking up from suspend-to-RAM:

it's a very long time I'm wrestling with the very same issue with my mobility
x1400. Today I found a workaround to did problem. I'm in kernel 3.2 of LMDE. 

To solve this problem I forced my GPU into the maximum compatibility 3D
acceleration mode with this simple xorg.conf

Section "Device"
    Identifier            "Radeon"
    Driver                "radeon"

    Option "EXAPixmaps"        "off"
    Option "AccelDFS"        "off"
    Option "MigrationHeuristic"    "greedy"
EndSection

I don't think it's the very same issue:


>     Option "EXAPixmaps"        "off"

This is a very big hammer which basically prevents 2D acceleration from
occuring in most cases, so it doesn't narrow down your problem very much
unfortunately.

Moreover, the original report here mentioned 'The effect does not show in
screenshots', which means this option can't really work around it. So your
problem is probably not exactly the same and should be tracked elsewhere.


>     Option "AccelDFS"        "off"
>     Option "MigrationHeuristic"    "greedy"

These options don't have any effect with KMS.
