@Cristian asking questions on how to fix your system is more of a support issue than something appropriate for a bug against a package. Try http://www.ubuntu.com/support for various methods of getting help.
Remember, if you use an officially unsupported driver (such as a driver downloaded from nVidia directly, as opposed to installing one from the Ubuntu archives) it is not officially supported. Hence the adjective 'unsupported'. The line 'Xlib: extension "GLX" missing on display ":0"' indicates a problem with your video driver installation. That's at least an indication as to where to start troubleshooting your problem. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1166765 Title: unity showing only blank desktop, no dash nor decorations To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1166765/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
