I can confirm this behaviour on a Samsung NC10. Deleting ~/.config/gnome-session/saved-session has an effect, the same flashing background occurs but the Ubuntu log in sound plays before entering the cycle.
Running "mutter --replace", all is well but if I then run unity, or issue "Running mutter --mutter-plugins=/usr/lib/mutter/plugins/libunity- mutter.so.0 --replace" I get: (unity:4943): Gdk-WARNING **: /build/buildd/gtk+2.0-2.20.1/gdk/x11/gdkdrawable-x11.c:942 drawable is not a native X11 window The program 'unity' received an X Window System error. This probably reflects a bug in the program. The error was 'BadWindow (invalid Window parameter)'. (Details: serial 516 error_code 3 request_code 20 minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) -- gnome panel conflict: Unity keeps reloading on my system and get white background... https://bugs.launchpad.net/bugs/578585 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
