Hi, Cause this mail is quite long - in short - problem solved (at least for this mailing list), I have still a small problem: - Right mouse click doesn't work in my x2go session: - Left click works, middle click, scroll wheel, even the additional buttons browser back and for are working, but not my ight, I always have to hit context-menu-key on keyboard which works. Can you give me a hint of whats going on and how to solve? - I'm using the latest (4.0.5.0) client version, problem is also on 2 x86 computers (1 client, 1 server) with both fedora 22 set up.
Original - analysed and solved problem: I went back to an x86-Client with fedora22 on it: - on the server deinstalled nomachine, which I tried for testing --> seemed to give some speed-up - used a preempt kernel -> no real change - changed the ssh encrypting to blowfish-cbc, arcfour -> little change (as aes is performant on i7, but not older models) - used kaffeine --> big speedup - If I'm using vlc the timebar sometimes moves on, but the video doesn't change. I don't know what this causes, perhaps some caching or vlc tries to write a direct write on hardware components. Parole-player seems to do something similar. kaffeine runs smoth, picture is not as good as if I'm sitting in front of my physical-pc (since I'm compressing here with 16m-jpeg), but good enough. So x2go-server seems to work at least it works so well, that I don't notice any real differences. So I tested with cubietruck (cubieboard 3.0, armhf, mali-GPU) as client once again: - nomachine, ssh and kaffeine have also given some significant speedup. At least a video covering one third of the screen (at 1920x1080p) is running really well, fullscreen is still a little but jumping, not as bad as before, but clearly visible. So my problem seemed to be a combination of slow server, "wrong" player, interfering package (nomachine) and a slow client. For now I'll try another linux image on client, perhaps the mali-GPU isn't supported right in my software or the x11 on the cleint is too old. Perhaps there is also a limit (I don't hope so) what cubieboard can do. But I think this will be a problem I'll better post in cubieboard forums. Thanks for your support!
