x2go can make you two types of sessions 1) the 'local screen' one that will have that resolution problem and 2) a 'detached' one that will be the size you like, for example fullscreen laptop sized. The 'detached' kind are quite a bit faster somehow, so I use that, and often re-connect to it from the local screen in a window when I get back to the desk. It's surprisingly practical, as my 'detached' session usually have a different window layout, tools etc.
