I was able to lock the screen again after just running "gnome- screensaver" without any arguments.
The bug appeared again, and this time I got the output from the command "gnome-screensaver-command -l": > The program 'gnome-screensaver' received an X Window System error. > This probably reflects a bug in the program. > The error was 'BadDrawable (invalid Pixmap or Window parameter)'. > (Details: serial 1551 error_code 9 request_code 53 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.) -- Screen lock unlocks after 5 wrong attempts https://bugs.launchpad.net/bugs/446395 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
