Bug Description

The video driver for my AMD GPU does not seem to be loading properly with kernel 5.13. The GUI loads but is stuck with a low resolution.

Output of 'lspci -v' command seems to show that no graphics driver is in use. I expect 'amdgpu' to be the selected driver for my GPU.

Everything works correctly if I restart the system and select the previous kernel version (5.11.0-44).

Additional info:
I have linux-generic-hwe-20.04 meta package installed (currently at version 5.13.0.27.29~20.04.13)

Probably missing firmware. Can you run 'apport-collect 1958914'?

I can't seem to collect the relevant data with that command. I'm receiving a popup saying 'No additional information collected', and on the terminal it says 'Package linux-signed-hwe-5.13 not installed and no hook available, ignoring'.

In fact I don't have any signed kernel packages. But I do have 'linux-image-5.13.0-27-generic' and 'linux-image-generic-hwe-20.04' currently installed.

If it helps, I tried re-installing the kernel metapackage and got the attached errors, which may be useful for troubleshooting this.
