are still seem to be (at least) parts of KDE 4 in F22.

Hmmm, is GLX needed even when using llvmpipe? If not, exporting
LIBGL_ALWAYS_SOFTWARE or QT_XCB_FORCE_SOFTWARE_OPENGL should work
around the
problem.

There are also some general Qt 5 compatibility issues reported, but those
seem fixed now according to:
http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=637#33

Another workaround would be to try LXQt instead (assuming the Qt 5 issues
are really solved now, see above). KDE applications should run fine under
LXQt, or any other desktop (e.g. Xfce) even.

Thanks! I was wondering if there might be some work around by setting
some environment variables.

I'll give it a try when I finally get my F22 alpha test system installed.

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
