I have x2go installed on a server system, a desktop and a laptop. All using 3.99.2.2, all running Linux Mint (Ubuntu variant).
When I connect from the desktop to the server, the keyboard maps just fine - all keys work as expected.
When I connect from the laptop to the server however, the keyboard map is messed up - home/end keys don't work, arrow keys map to other random keys etc.
I cannot figure out why this is happening, and no combination of the x2go keyboard settings seems to change the result. I have noticed when connecting from the laptop to the server if I check the keyboard map when connected I get "null". Trying to change it results in an error from the keyboard daemon for changing the xkbmap.
Is there anything I can do to try and debug this? It seems very odd that it goes so wrong from computer, but is perfectly fine from another, since the keyboards on both are configured to use the same generic 105-key layout.
