Hey,

On the wiki page http://www.x2go.org/doku.php/wiki:development:x2go-qa I
found these known issue: "On some servers Qt-applications have no window
decorations, reason is currently unknown." I'm running the x2go server on a kubuntu, an openSuse 11.4 and 12.1
machine and confirm this bug for every of these servers! So for me this
seems not to be a rare problem. All of the machines come with KDE but on
suse I also installed lxde. I really would like to help to solve this bug
but I don't know how. If anyone gives me a hint I could give more
information about the configurations on the servers. The decorations are missing at every program I tried, this includes pure
kde, gtk but also java applications.

Best regards Fabian
