Hello, I'm using PXE for thinclient and after loging out and waiting for a new logging window for a KDE session, *sometimes* a blue screen appears with a cross. Blue screen remains for 2/3 minutes after logging window appears again. PXE server is on a different machine.

application x2go server: 3.16.0-4-amd64 (Debian Jessie) with x2go packages for jessie.

PXE x2go server: 3.2.0-4-686-pae (wheezy) with x2go packages for wheezy.

thanks in advance,
