Clipboard doesn't work?
by Ingo Brückl 12 May '19

12 May '19

Hi, Is there an issue with the clipboard between a Windows client (v4.1.2.0) using the integrated X-Server and a connection to a local desktop on a Linux server (v4.1.0.3)? Whatever I tried, I wasn't able to copy or paste any data between them. What am I supposed to exactly do to use the clipboard? It is set up for bidirectional copy and paste, btw. Ingo

X2go Connection / compression Settings defunct? Documentation?
by Nigra Truo 01 May '19

01 May '19

Hi, I'm forced to work with some extreme bandwith restrictions and was looking into using more compression and/or the Modem / ISDN connection setting. (I'm down to old time modem speeds, 128 kbit or less) So far I could not find any documentation that shows what these really do. I normally use the ADSL one, which works. The Modem and ISDN setting seems broken (and has been for as long as I rememeber), they don't really reduce the bandwidth usage nor improve latency. When switching to Modem, the screen updates actually get much worse, I can watch the system update the screen in lines (not the whole screen is updated in one go), which looks like a bug. I have had success setting the image quality to a lower setting, the screen looks worse, which is a good indicator that it is working. I can't find any documentation on what the difference is between different compression methods. Can you point me in the right direction? If I can find the info, I would be up for updating the documentation so that others can find it better. Thanks Markus -- Por sperto kaj lerno ne sufiĉas eterno.

Hi All, This error msg has not reappeared since then. In the mean time, I updated the Ubuntu server. There seemed to be updates refering to nx-libs. I rebooted to the server.

x2goserver - Unable to open display

Hello, I am unable to connect to the x2goserver. I have 3 almost same servers with Ubuntu 16.04, on two of them x2goserver is working, but on the third not.

Different sessions for same user on server
by Dmitry Pavlov 28 Apr '19

28 Apr '19

Hello, Context. I have x2go server and different machines from which user connect to it (e.g. laptop and home pc). To connect same user on server is used and right now connection to same session is always done, i.e. if remote session is established from laptop, then x2go window was closed, then same desktop state is opened when connecting from home pc. Is it possible to adjust current behavior to have different remote sessions for different connections? Due to some issues with UI representation (different remote screen resolution, gnome menus change themes), current "one user - one session" mode works bad. I've seen mentions about session selection list on desktop sharing wiki page (https://wiki.x2go.org/doku.php/doc:usage:desktop-sharing?s[]=sharing) but did not get so far how to apply this for regular connections. -- Regards Dmitry Pavlov

Quick little trouble shooting instructions I set up for my users.
by Jeff Sadowski 22 Apr '19

22 Apr '19

My .bashrc starts like so if [ "$BASH_EXECUTION_STRING" != "" ]; then return 0; fi # do not add items before this line This helps with sftp and x2go if you have things that interfere with x2go or sftp like changing directories or adding paths that might interfere or just code block that might interfere. Always set the session type to XFCE default is KDE(not installed on all servers). XFCE is a lightweight desktop allowing more people to connect. if XFCE fails to start with a dbus error you may have a corrupted file in your home directory. One way to potentially fix this is to login with ssh and move all your dot files to a temporary directory like so mkdir -p ~/dot_files mv ~/.[a-zA-Z]* ~/dot_files After your dot files are out of the way try starting an x2go session. If it starts then one of the files was causing the issue. to move your files back that have not been created by starting x2go you can try this script I called restore_dot_files.sh #!/bin/bash #script to move back all files that where not recreated by starting xfce cd ~/dot_files ls -1 .[a-zA-Z]* | while read file; do if [ ! -e "${HOME}/${file}" ];then echo "moving back ${file}" mv "$file" ~/ fi done then try stopping and starting x2go and see if it still fails. If it fails then one of the files that is being copied back is causing the issue maybe ~/.bashrc I'd make sure you have the lines I have at the top of this article the top and bottom sections of my .bashrc and try again. If you are having issues with connecting to previous sessions you may need to login from a command line with an ssh client (like putty, or mobaxterm) and kill some hung sessions. Login to the server you can not connect to. Run: ps -fu $USER|grep x2goagent This will display your current x2goagent processes you have running Ex: user1::machine1 { ~ }-> ps -fu $USER |grep x2goagent user1 22323 1 0 Apr08 ? 00:05:22 x2goagent -nolisten tcp -nolisten tcp -dpi 96 -D -auth /home/user1/.Xauthority -geometry 800x600 -name X2GO-user1-53-1554730849_stDXFCE_dp24 :53 In this example if I can no longer connect to my x2go session on machine1 I would want to kill this process. So I would run: kill 22323 After running that see if there is still a process x2goruncommand by running ps -fu $USER |grep x2goruncommand Ex: user1::machine1 { ~ }-> ps -fu $USER |grep x2goruncommand user1 22383 1 0 Apr08 ? 00:00:00 /bin/bash /usr/bin/x2goruncommand 53 22323 user1-53-1554730849_stDXFCE_dp24 52312 xfce4-session nosnd D you will want to try and kill that process as well in this example I would use the following to kill it kill 22383 After you kill those two processes you should be able to connect to that server again using x2go.

Client window size issues (Windows client)
by Ingo Brückl 12 Apr '19

12 Apr '19

When trying to connect the Windows client with a max. resolution of 1024x600 to a local desktop that is 1024x768, there are problems with window mode. (Yes, I now. I usually create X2Go sessions, but sometimes it'd nice to connect to the local desktop.) The Windows X window has a fixed, far too small size (no matter what custom size you specify - 1024x600 or 1024x768). It's only about 1024x450 and is displaying a middle part of the desktop. Trying to resize the window causes it to crash. So I was wondering whether VcXsrv can't display with a vertical scrollbar, i.e. a 1024x768 desktop in a 1024x600 window? And in fact, it can. Please consider adding '-resize=scrollbars' to the command line options. One problem, however, remains: There is no cursor visible inside the X window (not even if using -swcursor). Is it fixable?
