Bug#1013739: linux-image-amd64: Boots with totally blank screens on docking stations; applies to all kernel image versions
Package: linux-image-amd64
Version: 5.10.120-1
Severity: important
X-Debbugs-Cc: axst@users.sourceforge.net
Dear Maintainer,
none of the kernel images show any text output (including encryption prompts) on any
screen as long as the laptop is on a working docking station. I have to remove the
computer from the station (or power off the station) so I can tell when to enter the
harddisk encryption passwords.
It does not matter which display is used for primary output, the effect is the same. After
Grub, the screen goes blank first with the backlight on, then goes totally dark.
If I enter the encryption passwords blindly and correctly at the right moment, the kernel
boots without problems.
I have tried video=efifb/i810fb/intelfb/LVDS-1:1366x768@60e etc. to no avail.
Boot messages show up normally without the docking station (and in the logs).
Grub, Wayland, X, Gnome etc. work without problems.
