Ever since the update to kernel 5.0 and higher, I can’t boot my Dell XPS 9570. I can still boot the old 4.20 branch and that works fine.
Booting to kernel 5.0 works up until the point where the Plymouth boot loader would normally appear on screen. However, it seems that at that point, the screen is turned off (there doesn’t appear to be any backlight anymore either). I don’t know if the system simply stops or if the boot is finished in the background without any visual feedback for me.
The only thing that I can find in the /var/log/messages is a slew of ACPI messages but I’m not sure they’re related:

etc.
I’d love to troubleshoot this further but frankly, I don’t really know where to start. Any help would be appreciated.
