have you taken a look at all of hardware specific driver files they put on the wiki page that were what got my install working?
my version is actually Debian 4.19.0-9-amd64 and a whole bunch of other crap after that specific to the laptop I installed it on
ill check what it says the VM is but I didn't know there was a 5 out I kind of don't want to upgrade it now if it fucks up it will ruin my Thursday lol
