Dell docking station problem, two extra monitors on startup

Hi,
Thankfull for any info how to possibly solve or where to find more info.

Problem is that when laptop is started in docking station the startup process goes to login screen phase,
but instead of login I get two blue screens with nothing. Also monitors do not repeat the last ascii
strings before login screen.

If I install laptop to docking station after startup It recoqnizes the monitors ok and can work with external monitors.

Monitors are lg and dell so somekind of startup scetch problem when docked before powering on the laptop?

Monitors are connected to docking station by DVI connectors. Basically computer can't be logged in/started if connected to docking station before powering it on. Bios password shows ok, the texts before forementioned phase scroll ok on other external monitor until two blue screens without any texts and jam there.

Just tried, if I blindfully write user and password while bluescreened I can log on and monitors function when linux running.
Grub advanced options show, but nothing else but blue on login screen while starting up from docking station.

It would be nicer to see login screen and devuan text. Any info/ideas?

Have a look at what dmesg and Xorg.0.log are printing out, there must be some clues as to what is happening there.

But I don't think it is a monitor problem, there may be an issue with the docking station.

How does the docking station connect to the laptop? eg: USB, special onboard connector, etc.
Is the laptop on batteries when this happens or does it have the charger plugged in?
If not, try it with the charger plugged in.

You may want to check the manuals (both laptop and docking station) and see if there is any related settings you amy need to check.

Best,

A.
