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.
