It's likely a drm/i915 change which is causing the regression. Probably one of these four candidates that we got through stable update to 2.6.38.8: drm/i915: Fix gen6 (SNB) missed BLT ring interrupts. drm/i915: disable PCH ports if needed when disabling a CRTC drm: Send pending vblank events before disabling vblank. drm/i915: fix user irq miss in BSD ring on g4x
In a hunch, I reverted "drm: Send pending vblank events before disabling vblank.", built, and uploaded amd64 packages at http://people.canonical.com/~herton/lp814325/r1/ Marc, can you test it? If it works, then try the 11.48 when it hits -proposed, just to double check. If it fails, then we got our change which introduced the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/814325 Title: fuzzy and corrupted display with update in natty-proposed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/814325/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
