--- Comment #2 from Evilandi666 (Evilandi666 at gmail.com) ---
I updated to Debian Buster which uses kernel 4.11.0-1-amd64 #1 SMP Debian
4.11.6-1 (2017-06-19) x86_64 GNU/Linux.

When setting the graphic card to the disrecete nvidia card everything works
fine :)

However, if I set it to hybrid graphics, I get a kernel error:
