It's x11 (as a matter of fact chrome-remote-desktop doesn't support wayland yet.) Also, I probably didn't make it clear: qbittorrent was able to show it's GUI fine - and you can actually interact with it like clicking menus, item list, details, etc. - before it crashes. So it's not obvious to me what the "could not connect to display" part it is referring to. > Christian > > -- Regards, Xiyue Deng
