Title:
Ubuntu 19.14 disco will not boot on Dell Precision5530
Status in gdm3 package in Ubuntu:
Incomplete
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
I'm uncertain which package is causing the problem, though I strongly
suspect it may be nvidia related.
This laptop runs 18.10 just fine, but attempting to boot 19.04 from a
USB disk (tried multiple USB boot disks) results in a blank screen
after Grub. The video will go between black with back light and black
without back light. I cannot switch to a TTY, I cannot get further,
keyboard seems to respond (lights up when keys are pressed).
Additionally, when trying to upgrade from 18.10 the same result
happens. After running the upgrade and rebooting, I cannot get it to
boot unless I first start in recovery mode from grub. After that I can
get to the desktop (nouveau driver seems to be installed by default).
Any attempt to boot normally results in a black screen. Attempting to
switch to proprietary nvidia driver results in never getting the luks
screen (encrypted disk). I get no luks screen when booting normally
either.
