Ubuntu 20.04 no driver loaded for Intel Iris Xe Graphics
I just got a new Asus Zenbook (UX425EA) yesterday which comes with 11th Gen i7 Processor + Intel Iris Xe Graphics, and I was facing the same problem too. After hours of google and scrolling through threads, I found one final fix which resolved the issue once and for all. You'll require the Ubuntu OEM kernel. Make sure to enable secure boot in the BIOS (last time I tried installing it without enabling the secure boot, the screen turned black with weird distortions, so I guess it will be an important step).
The following command does it all:
apt install linux-oem-20.04 && sudo reboot 0
If you have Intel Iris Xe MAX graphics, things get more complicated, refer here -> https://dgpu-docs.intel.com/devices/iris-xe-max-graphics/index.html.
This should do the job, but if it doesn't make sure that you have the packages as mentioned here -> https://dgpu-docs.intel.com/installation-guides/ubuntu/ubuntu-focal.html.
Hope this helps somebody. :)
Everything that I’ve read about the Intel Xe graphics points to it needing a more current kernel than 20.04 currently offers. You will likely need to upgrade to 20.10 to get the most out of your new system.
