This problem disappeared after current reboot by itself, but before this reboot the problem has been repeating all the time i restarting machine. I don't know what I have changed to avoid the problem. I remember that I have just updated list of 'application sources', but nothing installed... In previous version of Ubuntu I configered to use my extra buttons on the mouse (so I used Xmodmap).
Now everything is Ok , I hope it will be as well further ;) (Sorry, I am in hurry now, i will try to report all bugs that I receive) -- Many errors after updating while loading system https://bugs.launchpad.net/bugs/367729 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
