Title:
Blank screen hang on bootup with Ryzen 7840U iGPU with Noble
Status in linux package in Ubuntu:
Confirmed
Bug description:
TLDR - Looks like the amdgpu module is included in the Jammy kernel
images but not in Noble.
Hello!
I have a laptop with the AMD Ryzen 7840U CPU which has a 780M iGPU
running both Jammy-based and Noble-based distro elementary OS
releases.
This issue occurs only with the Noble and not Jammy edition.
Upon bootup with the "quiet splash" params there is just a blank
screen and apparent hang which is prevented if I remove the "splash"
option and then I get the expected login screen just fine.
Note that I ran the following command on both Jammy and Noble:
sudo lsinitramfs /boot/initrd-6.8xxxxx | grep amdgpu
And I see the amdgpu module is present in the Jammy image but not the
Noble image.
So I appended "amdgpu" to the /etc/initramfs-tools/modules file and
did:
sudo update-initramfs -uk all
Which resolves the issue for me with Noble as well.
Note both my Jammy and Noble installs are on the same kernel version
currently 6.8-xxx-40 although the amdgpu module is included in the
Jammy image but not the Noble one.
Thank you!
