Hi Daniel. Boot Splash Issue:
I removed "video=efifb". That didn't help. I applied "nosplash". That didn't help. I removed "fbcon=rotate:1". That didn't help. Removing this last one made things a bit worse. "fbcon=rotate:1" presence is necessary (at least in my system), otherwise, the console (during boot and shutdown) will present itself rotated 90 degrees counter-clockwise. My screen is always in Portrait Mode by default (even in the BIOS) and this kernel boot flag changes it to Landscape Mode (at least during boot and shutdown operations) which is what I prefer. So, unfortunately, these suggestions didn't help in the Boot Splash issue. For your reference... I also tried the following kernels without success: 5.6.0-1034-oem (focal-updates repo) 5.8.0-25-generic (groovy repo). I know that this kernel is not for Ubuntu 20.04.1LTS, but I was desperate. I even tried Linux Mint 20 Ulyana Live. No boot splash as well. Didn't had the time to install it though. ------ Logon Screen Issue: Editing /etc/gdm3/custom.conf and changing: #WaylandEnable=false to WaylandEnable=false It worked PERFECTLY ! For me, the boot splash issue is secondary when compared to the logon screen issue. Thank you very much Daniel! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1905184 Title: [Intel Gemini Lake] No video signal during Ubuntu splash screen and also during Logon procedure Status in linux package in Ubuntu: Incomplete Bug description: 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 logon screen and Ubuntu loads immediately. Problem: Boot splash won't be displayed anyway and 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. Workaround 3) Although I don't have video signal during Boot Splash and Logon screen, I do have backlight continuously applied to the display. If I wait 5 minutes or so in the logon screen the backlight will deactivate... However, when I touch the keyboard or touchpad the computer will then show video signal and I will be able to see the logon screen perfectly. Problem: I don't want to wait 5 minutes in the logon screen to obtain proper video signal.
