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?
R.

It sounds like when the script runs, the Xserver isn't quite ready, and xmodmap is waiting for that. Maybe you can start debugging by putting:
xmodmap -verbose -pm
before your call, to see what it prints out. And make sure the $DISPLAY is set correctly too!
You can also do an 'strace xmodmap ...' call in there, to see where it's going and what it's calling to.

I tried an "&", the session is starting, but xmodmap has no result, even with an extra "sleep 5" in a separate script. I'll try the "-verbose -pm" tomorrow.
Thnx for your answer,

Have a look at /usr/bin/x2goserver-run-extensions, this is the place where the extensions are called.
The call is
find "$X2GO_LIB_PATH/extensions/$X2GO_MODALITY.d/" -maxdepth 1 -mindepth 1 | egrep "/[0-9]{3}_[[:alnum:]]+" | sort | while read x2go_extension; do
which indicates that the script name has to start with _three_ digits followed by _ and an alphanumeric name. Your script does not match, so I guess that's the reason it is not executed.

The egrep above clearly rules out any non-matching file. So maybe this script is run by some other mechanism?

No, there is only one instance, in the right directory:

Alright, but I was refferring to your first mail where you wrote "010-xmodmap" which does NOT match. ;-)

I think you missed the first reply to my own post in which I wrote:

Not necessarily. "We're done resuming on the X2Go side of things" might not be the same as "We're up and running on the X-Server side of things". It MAY coincide, but I don't see a hard MUST for that.

Ok, then I will keep the 10 seconds sleep time, it's a workable solution :)

$DISPLAY is set correctly. The "xmodmap -verbose -pm" in a session works fine. Writing the output to /tmp/test.txt doesn't change anything.
You can also do an 'strace xmodmap ...' call in there, to see where it's going and what it's calling to.

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:
$ 'e'e'e'eééé

You should be able to simplify that into one script, assuming dash understands the syntax bash uses for this (haven't tried it):
$ cat /usr/lib/x2go/extensions/post-resume.d/010_xmodmap #!/bin/dash test -f ~/.Xmodmap || exit 0 (sleep 10; exec /usr/bin/xmodmap ${HOME}/.Xmodmap) &
Not sure why you'd need the "exec", even.
Instead of blindly sleeping 10 seconds, you could also check if xmodmap returns an error when it's called too early in the process. Maybe something like (while ! /usr/bin/xmodmap ${HOME}/.Xmodmap ; do sleep 1 ; done) &
Also, is there a particular reason why you need to run xmodmap manually/scripted, rather than using the keyboard settings option inside X2GoClient? Are you a macOS X2GoClient user, and the autodetection we need to use on the Mac is failing for you?

There's no need "exec" for it indeed

That would be a better option indeed

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.
