Title:
Screen Backlight Goes Blank and Won't Turn Back On
Status in linux package in Ubuntu:
Expired
Bug description:
I was working on my computer when all of the sudden the screen went
blank like it normally would after the lock screen comes on from
inactivity and eventually goes blank. However, it didn't go blank
from inactivity but instead just went blank randomally. It would not
resume the back light upon movement of the mouse or keyboard. You
could barely see the desktop and my bluetooth headphones were still
playing the music I had in the background. I had to do a hard reset
because I couldn't the screen well enough to run any sort of
diagnostics. After reboot the screen back light started to display
again without any problem. At first I thought it might be a hardware
issue but now I believe it to be a software issue.
