is there any possibility to use 2 or more monitors with my W530?
I have VGA and Thunderbold here, but i suppose that they just can be used with the dedicated Quadro K1000M, which is not supported by Qubes (as I know).
When you are able to get your hardware sorted, you should read this doc to make sure you’re assigning enough Video RAM for your total resolution: GUI Configuration | Qubes OS
