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?
