gnome-shell падает

Не могу запустить третий гном:

minor@localhost ~ $ gnome-shell --replace

(gnome-shell:10272): Gdk-WARNING **: The program 'gnome-shell' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
(Details: serial 141 error_code 1 request_code 136 minor_code 19)
(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.)
