Yes, it's true -cirrus hasn't changed. It could be a change in something underneath -cirrus that it depends on.
; in fact we haven't changed much of X in raring from quantal really: xserver is different but mainly just bug fixes, mesa the same (although since it affects gnome classic (no effects) it's not likely mesa's doing), libdrm has changed from 2.4.39 to 2.4.40 but DRI isn't being loaded so I doubt that's it: [ 10.229] (II) AIGLX: Screen 0 is not DRI2 capable [ 10.229] (II) AIGLX: Screen 0 is not DRI capable [ 10.683] (II) AIGLX: Loaded and initialized swrast [ 10.683] (II) GLX: Initialized DRISWRAST GL provider for screen 0 But I'm supposing that's going to be the same on quantal too. Reboot into quantal where you're not seeing the corruption, and collect Xorg.0.log (and why not dmesg too while you're at it.) Maybe the difference between those files will tell us something. ** Changed in: xserver-xorg-video-cirrus (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1080674 Title: [QEMU] Corrupted desktop screen for raring desktop installation in QEMU guest (Cirrus graphics).
