This hints at something else capturing the keypresses. So, emacs is
started by bash and bash naturally in a terminal, but what is this
terminal started from? A full desktop environment or the terminal
emulator as a single application in X2Go Client?

Starting up xev will likely put it into foreground and every X11 event
is printed out verbatim.

Make sure the pointer doesn't move, or you will be spammed with messages.

Pressing Ctrl will print a message with "Control_L" on the third line.

Afterwards, pressing "s" (hold Ctrl all the time) will print a message
having "s" in the third line and the fourth line will read XLookupString
gives 1 bytes: (13) "" if everything is working as expected.

Given that the key combination is not recognized in emacs and
LibreOffice, I suspect nothing will pop up in xev.

However, my basic test suggested that it's not a general X2Go problem,
as it's working on my machine(s) and I know a few users using
LibreOffice via X2Go. Naturally, Ctrl-S not working would be a grave
issue for them.


My current suspicion is that the keypresses are either captured by a
desktop environment or NX.

I understand that you have no control over the remote system as such,
but, if existent, what is the content of /etc/nxagent/keystrokes.cfg?
