Bug Description

After installation, the first boot works as expected - the system boots into a graphical shell login screen. However all subsequent reboots end up with a black screen with a blinking cursor in the top-left corner of the screen. To get to the login screen, one has to switch to a different tty (like tty2 with ctrl+alt+f2) and then to tty1.

Running `prime-select query` shows `nvidia`.

Interesting enough, when I change the nvidia-prime settings at least once, like to on-demand via `prime-select on-demand` - then everything starts working as expected. Even when I switch back to `nvidia`.

Not sure which package I should fill this under.
