With the most recent versions of x2go on Linux I've been having enormous difficulty with the keymap not being correctly applied - that is, the arrow keys, delete keys, home and end etc. appear to be mismapped between client and server, regardless of what I set the Keyboard settings to in the x2go client.
I'm using the Qt client 3.99.2.2. Does anyone know what the cause of this is? The machine I'm connecting from is a laptop, but that shouldn't be fundamentally changing the keycodes x2go reads?
