Hi, thanks again for replying.

I fear this may be out of my current reach, only given the amount of time I can devote to this. Hopefully you (or others with more familiarity with the Xorg project) may end up fixing this by applying "upstream" changes... or the problem may creep back on me and force my hand for good.

I would only use xterm to confirm that my changes hadn't completely crippled the libs. Frome there, I would invoke 'gnome-terminal' or 'gedit' to cause the segfault.

I can also look it up tomorrow when sitting at my notebook. Testing nxagent on localhost really eases the debugging and often let's certain issues disappear. If that happens, then the cause of observed issues may also be hidden in the libxcomp* libraries which handle the NX compression and caching part.

I will try that. Thank you for educating me... and thank you most for your service: x2go has been invaluable to my work setup for years now.
