Mint boots into a black screen, but it boots normally

Post by mizuhoid » Sat Nov 10, 2018 10:20 am

My laptop boots into a black screen but the system itself boots normally.
I can hear the sound of volume up/down hotkey and can use an external display.
In live USB boot, laptop display works fine.

# Symptom
Black screen on both X and virtual consoles. I tested KDE and Xfce but neither worked.
When I connect an external display, I can see X and virtual consoles on the external display but not on the laptop.
When I disable & enable the laptop display via System Settings(KDE) -> Display and Monitor -> Display: checkbox, laptop display shows the KDE Desktop but after changing to a virtual console, nothing is shown and then backing to the KDE Desktop, the display gets black again.

Very rarely, the laptop screen shows both X and virtual consoles, changing virtual consoles and X works fine but I don't know the reason why...

# nomodeset
nomodeset works and I got a low resolution but working laptop display.

# Question
Generally, what should I do first to find the problem?
