[Message part 1 (text/plain, inline)]
I could NOT reproduce the problem with your lightweight test on Linuxmint 22.1 Mate:

nxagent -ac :55

DISPLAY=:55 twm

DISPLAY=:55 soffice

--> OK (except maybe one fail, but that was probably human failure)


For the previous non-lightweight-test in twm on the remote Debian Trixie server I started in that x2go/twm session a terminal and from there soffice, since I couldn't find a direct Libreoffice launcher. So I tried this for the lightweight test - still works:

nxagent -ac :55

DISPLAY=:55 twm

DISPLAY=:55 xterm

In xterm: soffice

--> OK


I agree there must be something specific with newer Libreoffice versions, since I neither found this with other applications, nor with libreoffice 7.3.7. But as just discovered this is only an issue with (remote?) X2Go sessions.
