[X2Go-User] Questions regarding mate/video quailty

[Robert Dinse]

      I tried just now x2go at 1080p full screen from Ubuntu 15.04 client to
Fedora 22 server and I am not getting full motion video, it is reduced to
about 15 fps.

      I am in the process of troubleshooting to try to determine where the
bottleneck, but something broke my server since I last logged in with mate
and mate-settings-daemon is continuosly starting and dying so that probably
isn't helping.

      Once I get this resolved I'll try harder to narrow down where the 
bottleneck is occuring.  It's NOT bandwith at 1080p is using about 8Mbit/s
on a 25Mbit/s client connection and 100Mbit/s server connection and ping
times are still good so not network latency issues.
