Since this morning, it happens systematically after less than 5 minutes. The only solution I found was to kill the session (kill -9 -1... no very subtil, I know).

Is there a way to restart gnome-shell via command line? I now Alt-F2 and "r", but in my case it does not even work.

Here is the end of the output of strace:

My system is localized in French and I don't have any directory in /usr/share/locale ending with utf8 or UTF8.

I have the "en/LC_MESSAGES" directory, with files:
- gnome-control-center-2.0.mo
- gtk30.mo
- iso_3166_2.mo
- sos.mo

I also have a "en_US/LC_MESSAGES" directory with files:
- gcalctool.mo
- libxine1.mo and wget.mo

This error however does not seem to be fatal, while "write(2, "Window manager error: ", 22)  = 22
write(2, "Unable to open X display \n", 26) = 26" is.

I just unplugged the external monitor attached to my laptop and the problem seems to be gone (to be confirmed with time).

Should I use nvidia proprietary driver rather than the open source one?

Kind regards
