[X2Go-User] Black screen after pxe boot

[Olaf]

Hello!
While TCE boots via pxe (showing the progress bar) it uses only 25% of
the screen (1920x1080) in the upper left corner.
After booting the screen is black and displays a small "x"
for the pointer.

Other PCs / clients work, so I suspect that there is a problem with the
video driver. Does somebody has any idea?

Ubuntu 14.04
Client: Fujitsu FUTRO S550, ATI Radeon X1250

Greetings + Thanks,
Olaf
