Public bug reported:

Hello.

I don't have any video during Ubuntu splash screen and also during the logon 
procedure.
I only have video in GRUB and after the logon operation takes place.
After I type in my password (in blind mode), Ubuntu will then start normally 
with correct video settings (resolution, etc...).

To workaround this error, I can either:
Workaround 1) Enable automatic login. That way the system doesn't get stuck in 
login screen and Ubuntu loads immediately.
Problem: However, I don't want this because I'm in a multi-user scenario.

Workaround 2) Add a kernel boot option "nomodeset" in /etc/default/grub
When I do this I will always get video signal.
Problem: The computer is an ECS Hybrid Device (tablet+detachable keyboard), and 
when I use this workaround, user session loads in Portrait mode (not Landscape) 
and there is no auto-rotation support.

Computer is this one:
