Unfortunately, I cannot test anything because right upon booting, when the desktop appears, every app I start causes about a minute of freezing (even the mouse pointer freezes) and then a restart (or complete crash) of the unity top menubar and sidebar. The only thing in the desktop I customized was the Unity sidebar button size (in the settings app - to 16 pixels first, then to 24 pixels). But even the settings app caused this crash before I could use it to change the settings. I am writing this in a 640x480 Firefox window without window manager from within the crashed Unity desktop. Is this a known bug? I sure hope so. ;) ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: unity 7.1.2+14.04.20140220-0ubuntu1 ProcVersionSignature: Ubuntu 3.13.0-11.31-generic 3.13.3 Uname: Linux 3.13.0-11-generic i686 ApportVersion: 2.13.2-0ubuntu5 Architecture: i386 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CurrentDesktop: Unity Date: Sun Feb 23 09:58:45 2014 InstallationDate: Installed on 2014-02-22 (0 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Alpha i386 (20140222) SourcePackage: unity UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1283671/+subscriptions -- Mailing list: https://launchpad.net/~dx-packages Post to : dx-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~dx-packages More help : https://help.launchpad.net/ListHelp
