[X2Go-User] error
On one of my laptops I am not able to set up a connection to the x2go server. When starting a custom desktop: ssh-agent startx wmaker I get the black "x2go" screen and then crash. I see this in the logs: daemon.warn: Jan 26 11:41:54 /usr/libexec/WindowMaker/wmaker[483025]: (catchXError(startup.c:118)): warning: internal X error: RenderBadPicture (invalid Picture parameter) Request code: 139 Request minor code: 7 Resource ID: 0x4009d9 Error serial: 28162 I have more clients with the same version 4.1.2.2-2+b1 (Debian Testing) that connect to the same server and do not suffer from this issue.

[X2Go-User] Debian resume does not work anymore after update to 4.1.0.6
Client and server "Debian Testing" This morning I got server version 4.1.0.6 using apt. When connecting using client 4.1.2.3-1 it works, but after a resume the client says that the session is still running so the only way to get back to the server is to terminate the session and to create a new one. I downgraded the server to 4.1.0.3-7+deb12u1 and resuming works again. I run a command x environment: /usr/bin/ssh-agent /usr/bin/wmaker I'm at 1000km away from the server and as I use x2go all the time, so I won't be able for the moment to run some tests. Just FYI for the moment. I put these packages on hold: # apt-mark hold libx2go-config-perl libx2go-log-perl libx2go-server-db-perl libx2go-server-perl libx2go-utils-perl x2goserver x2goserver-common x2goserver-extensions x2goserver-x2goagent x2goserver-xsession in order to stay with version 4.1.0.3-7+deb12u1.

What I did is add a TMPDIR variable to the shell init script (I run sysV): /etc/init.d/x2goserver mkdir -p -m 700 /tmp/x2go export TMPDIR=/tmp/x2go The reason I use a subdir on /tmp is that if you write in /tmp the /tmp dir itself is modified (run 'stat /tmp/') and now everything takes place on a ramdisk. And /tmp/ runs on tmpfs in /etc/fstab: tmpfs /tmp tmpfs defaults 0 0 Maybe you may want to create a wrapper script in case you do not run sysV.

[X2Go-User] mouse 1 cm too low
Hello list, I have run x2go for many years now without any problem. I have two different servers running Debian testing and x2go 4.1.0.3-5, multiple clients running the same OS and x2go client. I run WindowMaker both on client and servers. This has worked for many years. Weird thing: the active clicking point for the mouse is 1 cm above the mouse. Restarting client and server does not make any difference. AFAIK these x2go versions have not changed (underlying libraries might have of course). I tested this on a few clients: same problem. It make x2go almost unusable. Anyone a hint what to test and where to look for this weird issue?

There is definitely something terribly wrong with this box. E.g.: I'm missing the link /dev/fd to /proc/self/fd. When I add the link manually (normally udev is in charge of this AFAIK) the x2go session starts, but cannot be terminated or suspended. There must be some bitrot somewhere.

No NFS, I purged everything and the db file is created:
ls -al /var/lib/x2go/
total 52
drwxrwx--- 2 x2gouser x2gouser 4096 Aug 12 16:22 .
drwxr-xr-x 41 root root 4096 Feb 20 10:37 ..
-rw-rw 1 root x2gouser 40960 Aug 12 16:22 x2go_sessions
Compared to the working server this is correct.

So, nothing wrong with the database IMHO

Is there a way to output debug info to syslog on Debian packages?

Hello list, server: Debian testing 4.1.0.3-5 client: Debian testing 4.1.2.2-2 Since this morning I get this (large) error message on *all* clients, connecting to *one* particular server that has worked for many years. I have another server, same OS, same version: no problem. The problem occurs when connecting to this perticular server. AFAIUK there has been no recent update for x2go in Debian testing. I removed all user x2go files, I removed x2go files in /var/lib/ and finally I purged the whole package, ran "apt autoremove" and purged all packages status "rc". Then I reinstalled the x2goserver: same problem. I fear it is some other package that messes up the functionality. Anyone a hint where to start?

[X2Go-User] x2gocleansessions
Hello list, I reported this issue earlier in the year, the process "x2gocleansessions" is checking for sessions each 2 seconds. The 2 seconds is on line 166 in /usr/sbin/x2gocleansessions: while(sleep 2) I have no idea why this process is started that often, but IMHO it's making quite a lot of noise for a 2 seconds check. It writes tmp files to the tmp directory and removes them. When using an ssd this will update the stat of the /tmp/ directory each two seconds. Can anybody explain why this process is started so often? Or is it still in a sort of debug/test mode? In my case I'm a single user on a single system, I changed the line 166 to 3600, but wouldn't it be a better idea to put that time into /etc/x2go/x2goserver.conf?

That sounds good :-) It would also be nice if the client name could be transferred to the x2go server, e.g. as parameter or environment variable to the extension scripts.

Ok, I already looked at the SSH_ environment variables but I cannot use IP :-( I have never played with keyboard settings, but would it be possible to create a per client keyboard layout that is sent to the server? I want to find a proper solution for automatically mapping keys. Now I need to invoke manually the xmodmap ~/.Xmodmap.clientname to set the different keyboards settings. A single session or resuming with the same computer is no problem, the issue occurs when resuming a session using a different computer than the computer which had initiated the session.

It's all Linux. I use a script to start WindowMaker as windowmanager
("Custom desktop") and I noticed that xmodmap keymapping is reset
after a suspend/resume cycle. I needed to run "xmodmap ~/.Xmodmap" each
time after a suspend/resume cycle. That's why I was trying to script it.
I use the x2go-server from various devices with sometimes some weird
keyboards. On some devices I mapped certain keys to functions like PgUp
and PgDn because otherwise these keys need "Fn + key" combination and
I'd like to keep these setting in the x2go session.
BTW, as stated in the OP, I don't think it's an x2go issue. Maybe I
have to play with the keyboard settings, I never did actually.

Hmm, this is a Q workaround:

test -f ~/.Xmodmap || exit 0
/usr/local/scripts/xmodmap.sh &

exec /usr/bin/xmodmap ${HOME}/.Xmodmap
After 10 seconds the xmodmap is executed, 5 seconds apparently is not
enough. I'm not an x2go guru, but in fact it would mean IMHO that
"post-resume.d" is executed before the session has really finished
resuming. After resuming the session I get this when typing "'" + "e",
when the 10 seconds have ended the "dead key" which is in ~/.Xmodmap
is starting to work:

[X2Go-User] execute xmodmap on resume
Hello list, Not an x2go problem, but maybe someone might be able to guess what is happening here. I made a chmod 755 shell script: $ cat /usr/lib/x2go/extensions/post-resume.d/010-xmodmap #!/bin/dash test -f ~/.Xmodmap || exit 0 /usr/bin/xmodmap -display $DISPLAY ~/.Xmodmap When resuming an x2go session, the script is executed, but x2go session starts but does not show up. The problem is that in one or another way, the xmodmap executable is waiting for something, but I have no idea what. Putting the xmodmap line to the background using an "&" makes the x2go session start, but the xmodmap mappings are not set. I still have to set the key mappings manually by invoking "xmodmap ~/.Xmodmap". Anyone a hint on what's going on here?
