Hi,
I've just setup a new x2go server (CentOS Linux release 7.0.1406). I installed using yum and the epel repo. I can ssh to the server without trouble. I'm running x2goclient on Max OS X 10.8.5. I have XQuartz installed and it works with other X apps.
=== When I try to connect, I get this in the x2goclient window:
NXPROXY - Version 3.5.0

On the server, I see this in /var/log/messages:

When I terminate the failed x2goclient session, the app crashes.
Does anyone have any suggestions about this? Thanks!

What x2goclient version are you using exactly?

Normal, nxproxy died (which it shouldn't have), so nxagent got SIGHUP.
When I terminate the failed x2goclient session, the app crashes.
Does anyone have any suggestions about this? Thanks!
Can you please start x2goclient manually from a terminal with the --debug option?
Normally by starting /Applications/Utilities/Terminal.app and issuing /Applications/x2goclient.app/Contents/MacOS/x2goclient --debug.
The last path may differ depending on where you put x2goclient.app.

Oh, and that's the good bit -- but very weird bit. "localhost" cannot be resolved on your system.
Have you ever edited /etc/hosts?
What is its content?
Normally, it should include at least the following entries: 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost
Which make localhost resolvable.

I hope I've done this in a way that doesn't steal anyone else's thread.
A while back someone posted that they had somewhat jerky video throughx2go, and I posted that if I watched someone on youtube over an x2go connection, with a 20 mbit/s cable connection, on a Ubuntu 14.10 client accessing a Ubuntu 14.04.2 LTS server, I also had some jerkiness to the video.
I have installed low latency kernels on both machines now and thateliminated the jerkiness. I can now watch a youtube video on a remote machine and have it display smoothly even with the highest quality setting set.
Just posting this so if others are experiencing this problem this may bea viable fix for them.

Robert this is very interesting.. mainly because I wasn't aware there was such a thing as a low latency kernel. Guess with linux you are always learning. However, I have an experimental question. Is it just the kernel on the video transmitting side, the client/receiver side or both that the low latency kernel has this impact? Also, if the video server side is linux with a low latency kernel then what would a client running x2go on a mac or a windows 7 machine experience since neither utilize a linux kernel ? Thanks for sharing as I had always figured it was a latency problem but I assumed it was 100% due to the network itself. Bria On Apr 1, 2015 5:23 PM, "Robert Dinse" <nanook@eskimo.com> wrote:

In Ubuntu, they build low latency kernels and make them available aspart of the distribution but not installed by default.
On my workstation, which is an old Mac-Pro 1,1 with quad Xeon CPU's and4 GB of RAM, I had Ubunto 14.04 installed then upgraded to 14.10. I had Wine installed and under Wine I ran WinAmp to play music. WinAmp sometimes skipped, and also when I upgraded to 14.10 which came with a 3.16.x kernel, I had issues with the Nvidia drivers for my old 7300 GT card.
To solve those issues I ended up building a 3.18.9 kernel and built itwith kernel preemption enabled, which is how Ubuntu builds their low latency kernels. That solved both my issues with Nvidia drivers and with WinAmp stuttering but it did not fix the issues of video being jerky over X2Go, and I had pretty much written that off to my Comcast connection anyway.
But given how much smoother things went on my workstation, I decided totry installing the low latency kernel on the server and then tried watching some Youtube videos that had previously been jerky (audio okay but video jerky) and found that it made the video smooth.
So my guess is you probably need it on both, but since I haven't triedit on the server only I can't say for sure.
The kernel on the server isn't custom built, it's one of the low latencykernels provided by Ubuntu (I used synaptic package manager to select and install, rebooted, then removed the old).
On the Mac I don't know. I had so much problems with X2Go on my Mac, even after installing the XQuartz server, that is one of the reasons I installed Ubuntu on it and stopped using MacOS. Got tired of the spinning beach ball, got tired of having zero games available. I liked the Dock but that's about it. Mac's approach of just throw enough hardware at it and it will be acceptable works if you have infinite money, I don't.
With respect to Windows, I only have an old antique XP machine that I usefor some games, don't really know how it would work with video over X2Go so can't answer that one.

I have installed low latency kernels on both machines now and thateliminated the jerkiness. I can now watch a youtube video on a remote machine and have it display smoothly even with the highest quality setting set.

Thanks for all of your information on the low latency kernel. I've used x2go for several years and one use-case I've had was to install the x2go server onto either Amazon's AWS EC2 or on Digital Ocean to support remote desktops for K-12 schools that I do volunteer work for.
Clients have always been a mix of Win7, Mac or Ubuntu linux.
Really the only issue has been video streaming which for K-12 is important because alot of learning content online consists of video.
In the past I've tried using larger "compute" instances (8-16 core) in those clouds thinking perhaps the video encoding/transmission load was the cause but that only improved things marginally.
I tried higher bandwidth links... same marginal improvement.
It didn't matter what client they used (mac, win7 or linux) the video content viewing results was more or less the same for each. That's why I am thinking maybe only the server-side "may" be required to have the low latency kernel??
I got them all so the streaming video (say youtube) wasn't awful but it wasn't the same as watching the video on a dedicated PC instead of thru the x2go virtual desktop.
But i guess I never suspected the linux kernel introducing delay/jitter to the point of being the cause.
It may take a while until I can get to it but I'll try and set up a test with one of those clouds and have the x2go server-side ubuntu utilize the low latency kernel you described and see what happens with each client.
This would be great if that turns out to be the source of streaming video jerkiness for cloud based remote desktops. I'll post something to the x2go alias when I find out what happens.
thanks again.

On my workstation, which is an old Mac-Pro 1,1 with quad Xeon CPU'sand 4 GB of RAM, I had Ubunto 14.04 installed then upgraded to 14.10. I had Wine installed and under Wine I ran WinAmp to play music. WinAmp sometimes skipped, and also when I upgraded to 14.10 which came with a 3.16.x kernel, I had issues with the Nvidia drivers for my old 7300 GT card.
To solve those issues I ended up building a 3.18.9 kernel and built itwith kernel preemption enabled, which is how Ubuntu builds their low latency kernels. That solved both my issues with Nvidia drivers and with WinAmp stuttering but it did not fix the issues of video being jerky over X2Go, and I had pretty much written that off to my Comcast connection anyway.
But given how much smoother things went on my workstation, I decidedto try installing the low latency kernel on the server and then tried watching some Youtube videos that had previously been jerky (audio okay but video jerky) and found that it made the video smooth.
So my guess is you probably need it on both, but since I haven't triedit on the server only I can't say for sure.
The kernel on the server isn't custom built, it's one of the lowlatency kernels provided by Ubuntu (I used synaptic package manager to select and install, rebooted, then removed the old).
On the Mac I don't know. I had so much problems with X2Go on my Mac,even after installing the XQuartz server, that is one of the reasons I installed Ubuntu on it and stopped using MacOS. Got tired of the spinning beach ball, got tired of having zero games available. I liked the Dock but that's about it. Mac's approach of just throw enough hardware at it and it will be acceptable works if you have infinite money, I don't.
With respect to Windows, I only have an old antique XP machine that Iuse for some games, don't really know how it would work with video over X2Go so can't answer that one.

In my case the client is old and rather under powered so it probablybenefited more than most would have.
Not being familiar with the internals or characteristics of Amazon'scloud, no idea how much that may or may not help. Hard to say how much latency and jitter is introduced by various cloud components like packet distributors, etc.

Robert I thought I'd get back to you on the low latency kernel discussion.
Over the weekend I created 2 "cloud" servers. One on AWS EC2 and one on Digital Ocean. On both of them I install x2goserver and the Ubuntu low-latency kernel.
At home I used a spare esata drive and installed the final beta of Ubuntu 15.04 onto it with the low latency kernel also.
My first test was with the x2go client on my normal home Ubuntu 14.04 machine.
All tests used: ubuntu 15.04 final beta on server side with low latency kernel installed (uname -r showed it as the active kernel) firefox v37 release same youtube video (I used Santana's "Smooth" video) x2goclient "connection" speed set to LAN (I also tried WAN with little observable difference) my home desktop is 8 core, 32GB ram, 6TB sata-6 sw RAID my home desktop internet connection is 20Meg
Test 1 use x2goclient to log into AWS EC2 "cloud" x2goserver start firefox goto youtube and watch a video client side did NOT have the low latency kernel
Result of test 1 video still somewhat choppy
Test 2 use x2goclient to log into Digital Ocean ubuntu x2goserver start firefox goto youtube and watch a video client side did NOT have the low latency kernel
Result of test 2 video still somewhat choppy
Test 3 use x2goclient to log into AWS EC2 "cloud" x2goserver start firefox goto youtube and watch a video client side DID have the low latency kernel
Result of test 3 video still somewhat choppy
Test 4 use x2goclient to log into Digital Ocean ubuntu x2goserver start firefox goto youtube and watch a video client side DID have the low latency kernel
Result of test 4 video still somewhat choppy
Test 5 Booted Windows 7 on my home machine, installed x2goclient and firefox v37 use x2goclient to log into AWS EC2 "cloud" x2goserver start firefox goto youtube and watch a video client side being Windows obviously did NOT have the low latency kernel
Result of test 5 video still somewhat choppy
Test 6 Repeated Test 5 (windows 7) but used DIgital Ocean ubuntu server again w/low latency kernel installed
Result of test 6 video still somewhat choppy
Test 7 Tried all of the above but using Youtube HTML5 video instead of Flash based video
Result of test 7 same as before ... somewhat choppy
My own results *were not able to replicate* your success with low latency kernel using this "remote" desktop x2go testing to cloud based x2goservers. So I suspect that the difference may be the WAN and/or cloud introduced latencies but that would take alot more work and probably some wireshark sniffing of packets to know for sure.
Finally, I remembered one "good practice" I had always been using and that was to install libjpeg-turbo on all my server's and my home PC clients (except the Win7 of course).
Reference: http://libjpeg-turbo.virtualgl.org/
The reason as you see when reading the above website is that libjpeg-turbo is 2-4 times faster coding/decoding jpeg than the default libjpeg in most linux distro's.
Retested here does show "some" improvement in video but still not as good as directly watching that same youtube using Firefox on my local desktop.
note: another benefit of using libjpeg-turbo is that besides being 2-4 times faster than default libjpeg it also uses less-cpu which for the server-side can be helpful when multiple x2go sessions are active or more than one x2go user is logged into that server
Anyway, I had hoped for a different outcome but unless I can think of something else I may/may not have done this approach didn't help much in my use-case of remote desktop to cloud serves.
Of course using x2go everything but streaming video from those cloud servers worked great.
If you can think of anything else let me know and I'd be glad to try to see if I can get diff results for the streaming video.

I don't know enough about their cloud servers to know what else to lookat, you're giving your low latency kernel CPU cycles from a cloud, how choppy is the scheduling of CPU cycles to your kernel fro the cloud? Your kernel can't schedual CPU cycles during times it doesn't have them.

It didn't matter what client they used (mac, win7 or linux) the video content viewing results was more or less the same for each. That's why I am thinking maybe only the server-side "may" be required to have the low latency kernel??
I got them all so the streaming video (say youtube) wasn't awful but it wasn't the same as watching the video on a dedicated PC instead of thru the x2go virtual desktop.
But i guess I never suspected the linux kernel introducing delay/jitter to the point of being the cause.
It may take a while until I can get to it but I'll try and set up a test with one of those clouds and have the x2go server-side ubuntu utilize the low latency kernel you described and see what happens with each client.
This would be great if that turns out to be the source of streaming video jerkiness for cloud based remote desktops. I'll post something to the x2go alias when I find out what happens.
thanks again.

In Ubuntu, they build low latency kernels and make them available aspart of the distribution but not installed by default.
On my workstation, which is an old Mac-Pro 1,1 with quad Xeon CPU'sand 4 GB of RAM, I had Ubunto 14.04 installed then upgraded to 14.10. I had Wine installed and under Wine I ran WinAmp to play music. WinAmp sometimes skipped, and also when I upgraded to 14.10 which came with a 3.16.x kernel, I had issues with the Nvidia drivers for my old 7300 GT card.
To solve those issues I ended up building a 3.18.9 kernel and builtit with kernel preemption enabled, which is how Ubuntu builds their low latency kernels. That solved both my issues with Nvidia drivers and with WinAmp stuttering but it did not fix the issues of video being jerky over X2Go, and I had pretty much written that off to my Comcast connection anyway.
But given how much smoother things went on my workstation, I decidedto try installing the low latency kernel on the server and then tried watching some Youtube videos that had previously been jerky (audio okay but video jerky) and found that it made the video smooth.
So my guess is you probably need it on both, but since I haven'ttried it on the server only I can't say for sure.
The kernel on the server isn't custom built, it's one of the lowlatency kernels provided by Ubuntu (I used synaptic package manager to select and install, rebooted, then removed the old).
On the Mac I don't know. I had so much problems with X2Go on myMac, even after installing the XQuartz server, that is one of the reasons I installed Ubuntu on it and stopped using MacOS. Got tired of the spinning beach ball, got tired of having zero games available. I liked the Dock but that's about it. Mac's approach of just throw enough hardware at it and it will be acceptable works if you have infinite money, I don't.
With respect to Windows, I only have an old antique XP machine thatI use for some games, don't really know how it would work with video over X2Go so can't answer that one.

Robert this is very interesting.. mainly because I wasn't aware there was such a thing as a low latency kernel. Guess with linux you are always learning. However, I have an experimental question. Is it just the kernel on the video transmitting side, the client/receiver side or both that the low latency kernel has this impact? Also, if the video server side is linux with a low latency kernel then what would a client running x2go on a mac or a windows 7 machine experience since neither utilize a linux kernel ? Thanks for sharing as I had always figured it was a latency problem but I assumed it was 100% due to the network itself. Bria On Apr 1, 2015 5:23 PM, "Robert Dinse" <nanook@eskimo.com> wrote:
I hope I've done this in a way that doesn't steal anyone else'sthread.
A while back someone posted that they had somewhat jerky videothrough x2go, and I posted that if I watched someone on youtube over an x2go connection, with a 20 mbit/s cable connection, on a Ubuntu 14.10 client accessing a Ubuntu 14.04.2 LTS server, I also had some jerkiness to the video.
I have installed low latency kernels on both machines now and thateliminated the jerkiness. I can now watch a youtube video on a remote machine and have it display smoothly even with the highest quality setting set.
Just posting this so if others are experiencing this problem thismay be a viable fix for them.

That would certainly eliminate issues with hypervisor latency. Unfortunately, I don't have the resources to do bare metal server testing at this point, but client is bare metal.

I understand that using a cloud server still involves some cpu sharing but I was interested in whether it would "help". I do know I can try the same using dedicated servers it will just cost a little more per hour but I can see about trying it next. On Apr 6, 2015 5:07 PM, "Robert Dinse" <nanook@eskimo.com> wrote:

Oh, and that's the good bit -- but very weird bit. "localhost" cannot be resolved on your system.
Have you ever edited /etc/hosts?
What is its content?
Normally, it should include at least the following entries: 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost
Which make localhost resolvable.
Interesting. My Mac's /etc/hosts is empty. I've added the text you posted above. Great! now it's getting further along. I get a new black window opening up with the grey x2go graphic in it, but then I get a sad comput face with the message: "Oh no! Something has gone wrong. A problem has occured and the system can't recover. Please log out and try again.
Running the client using the --debug option like before, I get this in the client's gui screen:

Looking at the more detailed x2go server installation page on your site, I then ran this:
yum install x2goserver-xsession
which succeeded, but doesn't seem to help.
I tried x2goclient with a terminal session instead of GNOME and briefly got what looks like an xterm terminal but then it closed. I won't post the debug output here since it's so large.
Do I need to install anything for the GNOME desktop on my server? I did the CentOS 7 install option for "server with GUI" (or similar, can't remember the exact wording). GNOME commands like gnome-session are on the server. But running gnome-session from the command line over an ssh session gives the same sad computer error page I describe above. Should it work to do that?
Thanks again for your help.

Oh, and that's the good bit -- but very weird bit. "localhost" cannot be resolved on your system. Have you ever edited /etc/hosts? What is its content? Normally, it should include at least the following entries: 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost Which make localhost resolvable.Interesting. My Mac's /etc/hosts is empty. I've added the text you posted above. Great!
Actually, that's pretty weird. Your /etc/hosts file should never be empty on OS X (or actually any other UNIX-based/like operating system.)
May I suggest your system is somewhat hosed and you should investigate what happened? Maybe even reinstall OS X? That's just a personal suggestion and has nothing to do with X2Go, but a missing /etc/hosts file has me concerned about what else might be messed up with that system...
now it's getting further along. I get a new black window opening up with the grey x2go graphic in it, but then I get a sad comput face with the message: "Oh no! Something has gone wrong. A problem has occured and the system can't recover. Please log out and try again. [...]
No need for a debug log here, the issue is clear. You're trying to start up GNOME 3. GNOME 3.10 and later are not compatible, older versions may be, but probably not. For more information, please take a look at:

Looking at the more detailed x2go server installation page on your site, I then ran this:
yum install x2goserver-xsession
Yes, x2goserver-xsession is recommended/required for full desktop sessions.

That's another known bug with new versions of GNOME Terminal. In recent versions, the program is forking into background and X2Go Server can't track that it's running anymore. Instead, it assumes the program terminated and also terminates the session.
We have a workaround for this, but I would rather like to rewrite the affected server script to fix stuff like this in a sane way.
However, take a look at yet another feature of X2Go Client (et al): published applications.
http://wiki.x2go.org/doku.php/wiki:advanced:published-applications
In that mode, you will be able to start GNOME Terminal and it won't quit on you right after starting.
[...] But running gnome-session from the command line over an ssh session gives the same sad computer error page I describe above. Should it work to do that?
About the same issue there: newer GNOME versions require a (newer) GLX extension. I guess that doesn't work at all via ssh -X and nx-libs's GLX extension is too old. That's a side-issue of the stale NX technology we're using. Work is done on improving this situation, but it's not trivial and requires a lot of work, so don't hold your breath for GNOME
= 3.10 or KDE >= 5 support any time soon, sorry...
