[Thinlinc-technical] Cannot open display after some time

[Peter Astrand]

We haven't heard of this problem before. However, my guess is that something 
removes /tmp/.X11-unix/Xn (where n is the session number) after some time. As I 
understand it, OpenSuse 12.1 uses "systemd", which is known to cause 
compatibility problems. I found this bug report:

https://bugzilla.redhat.com/show_bug.cgi?id=674194

It seems that you need to use systemd-tmpfiles v18 or later to avoid this 
problem. Or, use a Linux distribution without "systemd" :-)

Rgds,
Peter
