** Description changed: 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.
