As I said: "this is a Q&D workaround" Q&D means Quick and Dirty ;-)

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.
