Title:
5.8 kernel appears to break video in two groovy installs
Status in linux package in Ubuntu:
Confirmed
Bug description:
Ran apt to update/upgrade in both of my groovy distros, Lubuntu &
U-MATE 20.10 . . . on reboot not only was my grub list broken in both
cases but seemingly the update to the new 5.8.0-12 kernel shows splash
logo, but "logs" to a black screen. Display power light is "on" but
screen is black.
I repeated this several times in both systems . . . having to boot
using SG2 to another distro to repair grub . . . then after I did that
I got to grub list and went to "advanced options" and rolled back to
the prior 5.4.0-42 kernel . . . and GUI is operational.
I believe in TW I am running 5.7 kernel and that system has video. I
have an Nvidia card and I'm using "nouveau" as my driver.
