elementary OS 8 fails to boot with AMD GPUs only showing blank screen

[vjr]

After installing elementary OS 8 you may have failure to fully boot and only see blank screen on hardware with AMD GPUs.

You have two options... either permanently remove the splash option by removing it from the /etc/default/grub file then running sudo update-grub or, if you really want to preserve working splash then do the following:

Edit /etc/initramfs-tools/modules and add a line amdgpu to it and save, then run sudo update-initramfs -uk all to redo the kernel so that upon next boot it "should" properly display the boot splash logo/animation... 🙂

This will be preserved going forward even when there are new kernel updates - thanks to the addition of the amdgpu entry into the /etc/initramfs-tools/modules file.

HTH!

Good evening,
After installing Elementary OS 8, "Display Mirroring" does not work for me when I use an external monitor with my laptop. The system sees the monitor, the wallpaper appears on the monitor, but when I enable mirroring in the display settings, the setting is turned off. In other systems - Debian, Ubuntu, Linux Mint, Zorin OS, display mirroring always works for me. Can this error be fixed?
My laptop configuration is:
