Hi @5q8n67f2gvf, welcome to the Community! I’m happy that you like Qubes OS!
Indeed, and here is a relevant discussion: Why hasn't "Qubes way" become standard?.
Actually, it’s better to create a separate topic for every issue that you have. In this way, it’s easier for new users to find the solutions to their problems.
I am not an expert here, but it might be related to the nVidia drivers. See this and also there should be some solutions on this forum.
