I finally got around to trying KDE with x2go on F22 using:

export QT_XCB_FORCE_SOFTWARE_OPENGL=1

I can log in ok now, but its a bit slow, although my testing machine is 
rather old.

Can someone advise the 'right' place to put the export line please.

x2goagent sits there consuming between 50-100% cpu all the time. I'm not 
sure that that is expected and might be the cause of the slowness. Not 
sure how to diagnose this.

I found I needed to remove package kscreen to prevent the x2go window 
being resized automatically.

So, when I log in I get a single konsole window. The panel comes up 
momentarily but then appears to die.

How do I restart the panel from a terminal and where would I check for 
errors?

Also, resizing the x2go window makes konsole disappear. Its still 
running though and the x2go window eventually goes black.

Did anyone else try this yet? Anyone have any insight as to whats happening.

Thanks

Roderick
