@random1 I found out that this doesn’t depend on the desktop environment. This problem also exists in gnome. It seems like here’s the solution Debian HVM - small screen resolution but right now it’s not working - I repeated this command with my VM’s name and it didn’t help. Possibly, this setting is located in another directory in Qubes 4.3. I would be very grateful if you could help me find the setting for increasing Xen video ram and write the correct command
