[X2Go-User] Sluggish response

[Timo]

Hi,

X2Go Client v. 4.0.5.0 (Qt - 4.8.6)
GeForce GT 430 1GiB Driver 361.28
x2goserver 4.0.1.19-0~1064~ubuntu14.04.1
Ubuntu 14.04.4 local and remote
ADSL 7/1 Mbps

I have used x2go quite a long time to work from home. It have been 
working very nicely. But recently it have started to have very slow 
resume and sluggish response. It may take minutes to construct all the 
windows in the session at the resume and unminimize. Local desktop goes 
very sluggish as well. I have a lot of application windows open and 
using full screen session.

I have investigated a little an noticed symptoms like this: When I 
resume the session and get a chance to minimize it, I see that memory 
usage of graphics card have shot to 100% and Xorg takes 100% CPU. This 
happened just this morning. Then I launched Thunderbird locally and saw 
that the memory usage dropped to 10% and everything started to behave 
normally again. But then I suspended the x2go session, resumed it again 
and the same slugginesh and symptoms came back.

I have tried ADSL and WAN connection but didn't see any difference.

What should I try next? Can I somehow force Xorg/x2go not to commit all 
graphics memory or something?
