Hi,
I am currently testing X2Go to be a replacement for our (1GBit/s) LAN XDMCP setup. I have set up a Jessie X2Go-PXE server VM with a Jessie chroot env.
It is working in principle, I can get a connection and the advantage of session suspend/resume is great. (Although I had to remove the pulseaudio startup from the x2gosessiond to make it work.)
However, I have two problems: the X session only sees one "big" screen.
- How can I set client-specific X11 options? We have clients with complex multi-monitor setups. Xinerama doesn't seem to be working, either, once I have set the screens on the client (using Ctrl+Alt+F1, then xrandr) and connect,
- Speed: for small screen updates (menu items etc.) - I would guess < 10k pixels - X2Go is very speedy and responsive. For anything larger (Google Chrome being a serious offender, as it always updates the whole rendering area) it is much slower. Even just scrolling in Firefox is "laggy". Pure X is much faster for these large screen updates. I have tried various settings, 4k-jpeg is almost acceptable speed-wise but still not fast enough.
Test setup: X2Go-Server: Core i7-860 (4x2.8GHz), 24G RAM X2Go-PXE: VM with 4GHz AMD, 2G RAM Clients: Pentium D 2.8GHz, 512MB RAM, nVidia Dual-DVI graphics (model 6200 IIRC) with 2 1600x1200 monitors -> 2400x1600 total screen area. Clients use NOUVEAU and report Chipset: "NVIDIA NV44"
Thanks in advance for any hints,
Stefan
I'm neither having the problem with pulse audio or with screen update.But I've also got 4GB in the client and it's a Mac Pro-1 Xeon quad core machine.
I have no issues with lag on Firefox or Chrome, I use Chrome to watchNetflix video full screen and only very occasionally will I see brief lag.

Hi,
Have you tried 'adaptive' method with image compression set to ~7? Stable versions of X2Go client may not support this yet, so you'd need to use Nightly Builds. It improved user experience significantly - none of other methods worked so smoothly.
Best regards, Łukasz

That's a good question - maybe the problem is not x2go at all. Anyway, I found 'adaptive' working better in multi-user environment and more responsive in both single- and multi-user environments. Most of my testing was done using Ubuntu as server (within VM - Parallels Desktop). But my customers have also tested in real and found 'adaptive' behaving better. IMHO worth trying at least.

I am curious what desktop environment people having problems are using?I use Mate pretty much exclusively so maybe it's an issue with a different desktop, or maybe one of server resources, although my workstation is antique my servers are modern i7-6700k systems maxed out on RAM (64GB).
The only time I experience any issues if I stream 1024p media fullscreen,and then it's only an occasional stutter.
I am anxious to try the adaptive option but I am running vivid and therepository for nightly builds is only for debian / jessie. Is there a repository for nightly builds for vivid vervit?

Thanks Łukasz, I will try the adaptive codec. The client offers this (I compiled the client myself from the sources to be used in "Thinstation"), but I'm unsure how to verify that it is actually using it?
I think one reason might be the resolution, the workstation has 2x1600x200, i.e. 2400x1600 virtual screen size. With 1280x1024 resolution, the difference is not really that much noticable.
Also, do you think 512MB RAM in the clients to not enough?
I also noticed that when I set connection speed to "LAN", nxproxy (?) reports that differential X compression is disabled. As I understand, this is the most important feature of NX? Also, I think sometimes the SSH tunneling is a reason for slowness, since all traffic needs to be encrypted on the server and decrypted on the client. But I will also try with a different server, maybe there are other reasons.
Does any of you use Chrome? Is it also fast, especially when compared to Firefox?
