Dead (nearly blank) laptop screen, secondary screen works - how to fix?
- by LIttle Ancient Forest Kami
My laptop screen is black while my secondary screen is fine.
What I tried:
setting brightness (Fn keys) - no effect, no change seen, also on secondary screen
removing static electricity like suggested here - no effect
restarting / charging battery, running on battery / "wall" power - no effect as well
wait to see if warming it up helps - it doesn't
follow official Ubuntu diagnostics - checking now...
What I will try next:
check last updates I've made
IIRC I am running on nomodeset already, but can't recall how to verify this
Further symptoms:
can't see BIOS screen
system loads and works fine, just screen has problems
screen works (occasionally I could glimpse very dimly what was going on, but it was like with minimum brightness set - nearly non-distinguishable from just a black screen)
Any ideas how to proceed best? What is most probable cause?
