ubuntu 24.04 - Wayland - i915 firmware not loaded correctly

[Ionut Negru]

After upgrading from Ubuntu 23.10 to Ubuntu 24.04, I could no longer use Wayland. Logging in with Wayland resulted in a black screen.

A potential cause of the issue was that the update-initramfs procedure reported some missing i915 modules.

The folder /lib/firmware/i915 contained all the modules in a compressed format (.zst files), but the system was unable to load them.

I manually copied the uncompressed versions from the 10th of April, downloaded from linux-firmware.git, and the system, including Wayland, started working again.

I believe this issue might be related to the compressed modules option, and perhaps someone knows how to resolve it without this workaround
