<p>Hello,</p>
we are using x2go server and clients both on Ubuntu 16.04. After
configuring new clients on small single board boxes like a ZODAC
Zbox or a Raspberry Pi 3 we observe severe screen redrawing problems
an a very poor performance in video transfer. E.G. shifting a
Thunderbird-window over a Firefox-window the latter remains
scrambled with rests of Thunderbird.<br>
We didn't run into that problem in our former installation based on
Ubuntu 12.04. After searching for solutions in the compression
method and the CPU-performance of the clients I occasionally found
out that the problem disappears after connecting the client's
monitor via VGA instead of a HDMI connection. The problem even
disappears when a HDI/VGA-Adapter is used and the signal is fed to
the monitor via an VGA-input. This was tested with different
monitors. In our former clients we only used VGA connected monitors
and so we could not see the problems.<br>
The optical quality of a HDMI connected Monitor is notably better
than that of VGA connected one, furthermore the VGA connection seems
to become obsolete, so we would like to stay with HDMI.<br>
What can be the reason and is there a way change the HDMI-output in
to a suitable configuration?<br>
<br>
Best regards<br>
