Public bug reported:
It does not matter whether the machine crashed last time, it was a clean reboot
or shutdown, after the BIOS the display is black.
The boot process might continue, but I cannot see it. The machine (Lenovo T530)
have full-disk LUKS protection, so I cannot figure out whether it would boot up
and find a correct display. Some times I was trying to enter the LUKS password,
but no sign of booting.
If after that I turn it off and turn it on again, the machine boots normally.
lspci says this about the display controller:
