[X2Go-User] MATE desktop (Ubuntu Mate 15.10) cannot access in fullscreen mode

[Robert Dinse]

      The 15.95 rate is really what machines claiming 60 Hz are approximating.
It is the NTSC standard vertical refresh rate.  Has to do with how the chroma
frequency of 3.579545 Mhz divides by the horizontal 15.75Khz of NCST TV.  Not
to worry.  If your bars are being cut off then the vertical resolution of the
machine you are using X2Go to connect to must be higher than the full screen
resolution of your local monitor.

      Sorry on the apps, I was thinking between desktops.  Didn't read carefully
enough.  Not sure how to fix the apps as I always use the mouse for that.
