Yes, works for me on triple monitor Nvidia SLI setup, thanks, hope it becomes official. For those left wondering just run Synaptic Package Manager -> Settings -> Repositories.In the Software Sources dialog box select the Updates tab.Check the Pre-released updates (maverick-proposed) box.Run update-manager, restart and your'e done. --- On Thu, 23/12/10, mustangtyson <650...@bugs.launchpad.net> wrote:

Thanks! http://ubuntuforums.org/showthread.php?p=10268993#post10268993 -- You received this bug notification because you are a direct subscriber of a duplicate bug (659538). https://bugs.launchpad.net/bugs/650539 Title: SRU: Launching a Qt app crashes X when using Xinerama Status in X.Org X server: Unknown Status in “nvidia-graphics-drivers” package in Ubuntu: Invalid Status in “qt4-x11” package in Ubuntu: Invalid Status in “xorg-server” package in Ubuntu: Fix Released Status in “nvidia-graphics-drivers” source package in Maverick: Invalid Status in “qt4-x11” source package in Maverick: Invalid Status in “xorg-server” source package in Maverick: Fix Committed Bug description: Justification: ============= Regression from Ubuntu 10.04, causing an Xserver crash when starting a Qt application in an multi-head X configuration using Xinerama. The X crash risks losing user data from unsaved documents in applications. Fix: === This is caused by a typo in commit 80b5d3a3. A fix has been pulled to the server-1.9 stable branch in commit 3effb61e (http://cgit.freedesktop.org/xorg/xserver/commit/?id=78f94f19aab66a1e5331df0ce29f36e310b4195d ). This commit has been cherry-picked onto the Natty xserver tree. Test case: ======== Start a Qt app such as Skype while using Xinerama multi-head. Users of the binary nVidia driver who have multiple monitors and select “Separate X screen” rather than “Twinview” in nvidia-settings will be using a Xinerama multi-head configuration. Regression Potential: ================== Low. Patch is a one-line typo fix, and anything which exercises this codepath currently crashes. Original report: PROBLEM ======= Starting a Qt app such as Skype crashes X, leaving "Caught signal 11 (Segmentation fault). Server aborting" in Xorg.0.log.old and the dazzled user with the login screen. This is a bug in X, fixed upstream in http://cgit.freedesktop.org/xorg/xserver/commit/?id=78f94f19aab66a1e5331df0ce29f36e310b4195d . WORKAROUND ========== Until the fix is released as an official Ubuntu update, Jared Bunting has it in his PPA at https://launchpad.net/~jared-bunting/+archive/xorg-xserver-650539 (thx!).
