Problems with X2Go locking windows clipboard
by David C. Partridge 31 Jan '25

31 Jan '25

I recently upgraded an LUbuntu 20.04 system with X2Go installed to LUbuntu 22.04. As part of that process, the X2Go server components got updated to 4.1.0.6-0~2023081 I don't know what version it was previously but it was at least 3 years ago that it was installed. Since then whenever I copy text in (e.g.) a bash terminal session on Linux system I am connected to, the Windows clipboard appears to get locked and I can't copy stuff from a Windows application to the clipboard. It either doesn't get copied or worse, the last text from the Linux system that was copied appears in the Windows clipboard. The X2Go Client on Windows is unchanged (4.1.2.2) Is there any fix for this? Thanks David

Can't connect to Ubuntu Desktop

Hi, I'd like to connect from a Windows 10 Box to an Ubuntu 22.04.5 Server. It does not work. Either a X2go windows appears for a few seconds and vanish afterwards, or a window appears saying "Something has gone wrong".

I googled already around but didn't find a solution. Any idea ? Thanks.

Cant resume sessions X2Go + PostgreSQL
by Jooris Mettler 06 Jan '25

06 Jan '25

Hi there, I have a severe issue with x2go. There are 4 Servers (ubuntu 20.04) and a single PostgresQL Database running in Docker on a 5th device. It all started after noticing that some users couldn´t resume sessions, this seemed to spread to all users over several months. Restarting the Server fixed the issue short term, but is not an option to do frequently. Some things I noticed: 1. the users ~/.x2go gets filled up with references to /tmp/.x2go-<user>/<session-id> and ofc /tmp gets populated accordingly. Once a Session is closed, everything persists there. Since /tmp will be cleaned on a restart, I would assume some job would also delete these old references going to nowhere, but it does not happen. 2. While I can click the "suspend" button on the client, the session will not change on the server. Even manually running x2gosuspend-session <session-id> on the server via e.g. ssh and checking the status via x2golistsessions returns |R| for the session in question. 3. when suspending a session, I would expect it to create a folder in ~/.cache/sessions/xfce4-session-<servername:number>. It does not. If I try to connect to a still running (server side, but from client side "suspended") session, it will either prompt a wrong credentials error or continue normally, except no window will ever show up. In x2goclient debug mode It will not whow the reappaering "searching proxy for window: <session-id>" but will simply stop after: "x2go-DEBUG-../src/sshmasterconnection.cpp:2065> Executing remote: "bash -l -c 'echo "X2GODATABEGIN:cb3d39c0-4759-419a-a1da-7c6681410a50"; export PATH="/usr/local/bin:/usr/bin:/bin";export TERM="dumb"; x2goresume-session <session-id> 800x600 lan nopack us auto 1 both no; echo "X2GODATAEND:cb3d39c0-4759-419a-a1da-7c6681410a50";'" x2go-DEBUG-../src/sshmasterconnection.cpp:2082> New exec channel created. x2go-DEBUG-../src/onmainwindow.cpp:10344> Resolved localhost. x2go-DEBUG-../src/onmainwindow.cpp:10372> Port already in use: 6002 x2go-DEBUG-../src/onmainwindow.cpp:10602> X.Org Server started on DISPLAY 2. x2go-DEBUG-../src/onmainwindow.cpp:10824> All helper servers for Windows are started." No window shows, I can not resume a session. I can run terminate and it will not show up anymore on the list on the client side or using x2golistsessions, but it will still be there in the database. 4. Having a look at the database, I can see thousands of entries. Most of those sessions dont exist anymore, no user can connect to them, they are not shown using x2golistsessions. I thought I could simply delete them like shown in the wiki (https://wiki.x2go.org/doku.php/wiki:advanced:multi-node:x2goserver-pgsql?s[…) but it does not work. Trying to delete any entry will always result in DELETE 0. I hope someone has an Idea or that this is helpful in any way to debug and improve x2go. Best, Jooris
