Hi there,
I use lightdm-gtk-greeter as my login manager.
Once I locked my screen with 'dm-tool lock', and try to light my
monitor up again, graphic on monitor flashes (graphics on my laptop
monitor moves very fast from right to left).
But monitor on my HDMI port can display normally.
If I input my username and password correctly, the laptop monitor
just blank, I have to use 'xrandr --output eDP1 --off & xrandr --output
eDP1 --auto' light it up again
any on knows how it happens ?
below is my lightdm log:
