Newly installed Ubuntu on a Lenovo laptop - less than 24 hours old. Just
now, I revived laptop from sleep or hibernate and the display was frozen
and corrupted. The bottom 1/3 of display was a patchwork of small
squares of junk in green, pink, blue; top 2/3 of screen was a slightly
distorted version of the default orange/purple background and the clock.
I couldn't interact with the computer with mouse or keyboard - no mouse
pointer, no control-alt-delete, no control-backspace. I found alt-PrtSc-
reisub on google and was able to reboot from the keyboard. I'm running
18.04.4 LTS, on 2017ish Lenovo E450 with AMD Carrizo graphics card
