I stumbled upon this bug report https://bugzilla.redhat.com/show_bug.cgi?id=1659810 which seems quite similar, as well as this one https://bugzilla.redhat.com/show_bug.cgi?id=1520682
>From those sources I was able to fix my problem by 0. checking whether /lib/firmware/amdgpu/polaris11_k_mc.bin exists (was missing for me) 1. downloading the firmware file from here https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu/polaris11_k_mc.bin 2. putting it into /lib/firmware/amdgpu/ 3. Rebuilding my initramfs with 'dracut --regenerate-all --force --install "/usr/lib/firmware/amdgpu/*"' So somehow the firmware files have gone missing in the newer kernel. ** Bug watch added: Red Hat Bugzilla #1659810 https://bugzilla.redhat.com/show_bug.cgi?id=1659810 ** Bug watch added: Red Hat Bugzilla #1520682 https://bugzilla.redhat.com/show_bug.cgi?id=1520682 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1844847 Title: System isn't using amdgpu so its defaulting to vesa driver.
