Resuming x2go session leads to invalid keyboard layout: 

- Up arrow does nothing

- Down arrow acts as Enter

I was able to fix it by renaming inside /usr/bin/x2goresume-session keyboard_type='null\/null' to keyboard_type='null/null' (removing the backslash).

Please check why you had a backslash in the first place and fix it.

Server OS: Debian 13

Client OS: Debian 13

Client x2go version: 4.1.2.3

Client x2go settings: Input/Output -> Keyboard -> Auto-detect keyboard settings
