Getting Linux Mint 21 and Trisquel 11 working on the T4 laptop

There are issues with Linux Mint 21, Trisquel 11, and similar Ubuntu 22.04 based distributions supporting the 13th generation due to outdated graphics stacks and kernels, but these can be worked around by utilizing remastered images that contains updated kernel and graphics stack components.

Future releases of your favorite distribution should work out of the box and this is a temporary work around in the mean time.
