x2go much slower than vnc?
by Johann Petrak 01 Oct '20

01 Oct '20

I just learned about x2go and wanted to try it out for a remote session to a host I have so far done using vnc serving a xfce desktop. But sadly my observation is that x2go is *much* slower and less responsive than VNC. For example just moving around a window on the desktop (same size) works smoothly with VNC but is done in a very coarse fashion in x2go with the window jumping around slowly and with considerable delay. Both connections go over the same ssh tunnel, same kind of LAN so all other things the same, the problem must lie with x2go or the x2go settings. Is there any explanation for this or anything that could be changed to increase the speed of x2go? Is x2go not *supposed* to be faster than VNC? I have experimented a bit with the connection speed and compression settings but that did not change anything either.

x2go disconnects on paste (openSUSE Tumbleweed)
by Tristan Miller 01 Oct '20

01 Oct '20

Dear all, Today I updated from openSUSE Tumbleweed 20200708 to 20200724, and now whenever I try to paste the clipboard contents into a single application launched remotely via x2go, the x2go session disconnects and terminates. Does anyone else here have the same problem, or know what the culprit might be? Regards, Tristan

Losing mouse click ability and keyboard events
by Nicolas Ecarnot 01 Oct '20

01 Oct '20

Hello, First post, thank you for welcoming me here. From an Ubuntu 20.04 client to an Ubuntu 20.04 server, the default repository install is working out of the box, all is nice. But from times to times (random but around 15 min. ), with no obvious reasons, I'm losing the ability to click : - the display is still fine - the mouse cursor is still drawn - when moving the cursor, it is reacting to the windows borders, URL links, any sensitive parts of the display - but no mouse button click seems to be sent - no keyboard stroke seems to be sent either When killing the client and connecting again, the display is still fine, but the same problem remains. I tried to run the x2go client from a terminal to have a look at what could be wrong, but nothing obvious came to my mind. I tried to have a look at the server's log but I found none. I don't know if I could run the client and/or the server with additional verbosity to try to get more hints? Does that look like something familiar? Thank you -- Nicolas ECARNOT

x2goclient goes 100% CPU
by Lorenzo Iannuzzi 24 Sep '20

24 Sep '20

I read of similar issues in the past, but none seems like mine. If I leave x2goclient running and I don't use my PC for a while (like half an hour or more) when I return I find sometimes it runs at 100% CPU. Killing and restarting it solves the issue, but usually it occurs some time for my machine to reply to input when it happens. I have a Debian 10 (x2goclient 4.1.2.1) and I connect to the server (still Debian 10) by a Forticlient VPN and a Gnome session. I could provide more information, if you told me how. -- Lorenzo

Lag in RStudio desktop in nested ssh sessions (or qsub -I) MacOS clients
by Scott Wood 24 Sep '20

24 Sep '20

Hi folks, Multi-layered one here. We have x2goserver (4.1.0.4-0.0x2go1.0.git20200228.1815.heuler.el7) available on a (CentOS7) login node of our HPC cluster for folks to submit jobs from. If they start an x2go client session from a Mac to our login node, submit interactive jobs with X11 tunnelling enabled (or even just ssh -X directly to an execution node) and run RStudio (1.1.463) desktop from within that second host, there is an un-usable lag in their session. If they type in the console, it can take up to 10 seconds to register and display the keystroke. No errors, everything works, it just isn't very responsive. Linux x2go clients are fine. Windows x2go clients are fine. I know that's a lot of layers they're going through but I'm at a loss for identifying which layer is the issue. Any troubleshooting tips? Anyone out there experiencing similar symptoms? Cheers

x2gi broker, wsgi
by Gil Laycock 18 Sep '20

18 Sep '20

Hi, I'm trying to set up an x2go broker using x2gobroker-wsgi, and it seems to be almost working - but fails at the last hurdle. I have a pool of x2go servers running (that work fine individually); and listed in a pool in x2gobroker-sessionprofiles.conf (They do require an ssh proxy, which I specified in the sessionprofiles) I have a central pgsql db successfully recording sessions for the x2go servers. On the broker server, from the command line: * using x2gobroker-testauth succeeds * the load balancer seems to be working fine * command line running x2gobroker --task listsessions shows the session configured in x2gobroker-sessionprofiles.conf I have the x2gobroker-wsgi set up as a virtualhost. With debugging turned on, and most authentication disabled (so I'm expecting to have to log in first to the broker multiple times), I can visit in a browser to https://broker.my.domain/plain/ (also to .../plain/inifile ) and it just says "Access granted". If I use x2goclient, I try x2goclient --broker-url=https://broker.my.domain/plain --debug In x2goclient I then get a login screen, followed by a pop-up error message: "Host requires authentication"; the debug messages say: Broker HTTP request failed with error: "Host requires authentication" The apache log file just shows successful connections. I was expecting to get a choice among the pool of servers... I feel like I am missing something small but critical. -- Gilbert Laycock GnuPG key: 35B6A094 gilbert(a)laycock.org.uk http://www.laycock.org.uk/

x2go by verified developers for macOS
by Felix Kretschmer 15 Sep '20

15 Sep '20

Hi @all, I love to use x2go for remote connections from remote work to company-internal server machines. Since I am using a macOS machine to get my stuff done I am not able to use this anymore because company policies only allow Apple notarized applications to be installed on the machines. Are there any plans to notarize the x2go client for macOS? Best, Felix -- Felix Kretschmer E-Mail: fk(a)hubspace.de
