Yeah, that's rough. My only other thought is to possibly drill a grommet hole or two in the desk and cover it with something like this. As long as it looks professionally done, most places won't give you shit for making minor modifications that improve the functionality of your rental. But again, that's going to depend on how exactly the dorm is set up. Just wanted to throw an additional idea out there in case it might be relevant.
Cut a hole in the desktop.
