From: Egbert Eich <eich@freedesktop.org>

Subject: [PATCH 2/6] VNC: Readd timeout when vnc viewer connection breaks.
Patch-Mainline: Currently no upstream project.
Git-commit: 759b49ed1c4ea03e45433c92c2fb8c44a60db34a
Signed-off: Egbert Eich <eich@suse.de> 
References: bnc #441935, bnc #403901

This prevents Xvnc busy loop forever waiting for a viewer that no longer
response due to network or other issues.
