Sorry, that crashes. I will attach the file /var/crash/_usr_bin_gnome- shell.1000.crash.
The following is stdout: $ gnome-shell --replace Window manager warning: Log level 6: The program 'gnome-shell' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 345 error_code 8 request_code 140 minor_code 30) (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 GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)
