There could be several different reasons for this. Please install inxi and report the output of "inxi -G" in the terminal so we have some idea of your graphics hardware and driver situation.

Unable to locate package inxi

Come to think of it I didn't have an option to load non-free software. How do I get those?

you will have to edit /etc/apt/sources.list

Code: Select all

sudo nano /etc/apt/sources.list

at the end of each line you will have to add contrib and non-free, like this:

deb http://ftp.nl.debian.org/debian/ buster main contrib non-free
deb http://security.debian.org/debian-security/ buster/updates main contrib non-free
deb http://ftp.nl.debian.org/debian/ buster-updates main contrib non-free

next, you do

Code: Select all

sudo apt update && sudo apt upgrade

If they can't install inxi, which is in the standard Debian repo, something's wrong with their sources or connection to the net. Usually its because the installer couldn't make a connection, so disabled all the Net sources.

Can you cut and paste the output of

Code: Select all

cat /etc/apt/sources.list

here?

I've just had the same problem with CInnamon, it appeared a driver was missing for my Radeon graphic card.
Try to look at the messages at boot if it doesn't say anything about a missing driver, or look in /etc/var/log/kernel.log.
If it is a common driver problem, you'll most likely need to allow the non-free repos in the sources.list and then install the corresponding package.
