[Maverick] Flickering on Radeon - please cherry pick 646d2e9fbc41bf49075013009e9583bec4a51168

Hi Dave,

        Please attach the output of `lspci -vvnn` too.

    [This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

Attached lspci -vvnn but hey, this bug is pointing to a specific fix that needs to be pulled in so it's not really relevant.

Dave

mesa package proposed by Dave Gilbert solved this bug #610541 (without having to add xorg-edgers repository)
(opengl apps don't flicker anymore !)
Thanks !

This is also fixed by sarvatt/mesa ppa with the package versions 7.9~git20100909-0ubuntu2~lp631413

We believe this bug is fixed by this package, if it is not please reopen this bug.

mesa (7.9~git20100909-0ubuntu1) maverick; urgency=low

  [ Robert Hooker ]
  * New upstream git snapshot up to commit 94118fe2d4b1e5 (LP: #631413)
  * New features include ATI HD5xxx series support in r600, and a vastly
    improved glsl compiler.
  * Remove pre-generated .pc's, use the ones generated at build time
    instead.
  * Remove all references to mesa-utils now that its no longer shipped
    with the mesa source.
  * Disable the experimental ARB_fragment_shader option by default on
    i915, it exposes incomplete functionality that breaks KDE compositing
    among other things. It can be enabled via driconf still. (LP: #628930).

  [ Christopher James Halse Rogers ]
  * debian/patches/04_osmesa_version.diff:
    - Refresh for new upstream
  * Bugs fixed in this release:
    - Fixes severe rendering corruption in Unity on radeon (LP: #628727,
      LP: #596292, LP: #599741, LP: #630315, LP: #613694, LP: #599741).
    - Also fixes rendering in gnome-shell (LP: #578619).
    - Flickering in OpenGL apps on radeon (LP: #626943, LP: #610541).
    - Provides preliminary support for new intel chips (LP: #601052).
  * debian/rules:
    - Update configure flags to match upstream reshuffling.
    - Explicitly remove gallium DRI drivers that we don't want to ship.
  * Update debian/gbp.conf for this Maverick-specific packaging
  * libegl1-mesa-dri-x11,kms: There are no longer separate kms or x11 drivers
    for EGL, libegl1-mesa-drivers now contains a single driver that provides
    both backends.

Yep, fixes rendering issue for me - but ia32-libs needs a rebuild to pick it up, and hence google-earth on 64bit still suffers from this.
Added ia32-libs to bug.

Dave

I've refreshed the packages in ia32-libs a couple of times in the last few days. Can somebody test if it has picked this change up now?

I'm not going to have a chance to try it again until the weekend. However,
ubuntu6 was good for me last weekend.

Confirmed, this is now fine on 20090808ubuntu6

I can't confirm this bug as fixed on a laptop with ATI Radeon Xpress 200M

I've just installed Maverick on my desktop and have flickering as described here every few seconds on a totally clean installation. Changing resolution, frequency or "Visual Effects" setting doesn't help. My GFX card is an ATI Radeon X1600.

Either this bug was not properly fixed and has resurfaced or a very similar bug has disappeared.

Here, on my family's pc, the monitor is still heavily flickering, very,very annoying.. :\
The problem doesn't depend on compiz.
Ubuntu Maverick fully updated, no external ppa added.

Please note this bug is not a general bug about flickering.
This was a particular problem that is now no longer present in Maverick.

If you are seeing flickering please file a separate bug describing your hardware.

Dave
