I have 2 GPUs (already tried removing one of the GPUs and gdm is still not starting). It freezes with a blank screen.
The main card on the box is Geforce GTX1080TI. I already tried removing one of the GPUs and booting the system with just one of the cards.
System: Linux kali 4.19.0-kali4-amd64 #1 SMP Debian 4.19.28-2kali1 (2019-03-18) x86_64 GNU/Linux
(GDM is with debug mode enabled)
