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with Linux Mint 21, Trisquel 11, and similar Ubuntu 22.04 based distributions supporting the 13th generation due to outdated graphics stacks and kernels, but these can be worked around by utilizing remastered images that contains updated kernel and graphics stack components. Besides this there is a fix that must be applied after a remastered install is performed. This is because there is an issue with support for the nvme controller. Future releases of your favorite distribution should work out of the box and this is a temporary work around in the mean time.

To get power management and other functionality like the (webcam) working fully under Linux Mint 21 and similar distributions (5.19 kernel via the LTS enablement stack) do the following (must be used in conjunction with a remastered disc):

Trisquel 11 remastered

Note: You need to be connected to the internet to install Trisquel 11 or Trisquel will show uefi grub related error messages.

Linux Mint 21.2 remastered

Linux Mint Debian Edition 5 (LMDE5) remastered (mesa & kernel upgrade required for 3d)


1. After installation open a terminal window and gain admin access (click activities or your menu and search for / go to terminal):

Once at the terminal and (or in the chroot environment enter the following command):

nano /etc/default/grub

3. Find the line that reads ‘GRUB_CMDLINE_LINUX_DEFAULT‘ and append ‘ acpi_osi=! acpi_osi=Linux’ to the end (without the quotes)

Save it, to save the file: CTRL+X, Y, ENTER

4. Now, update your grub file and reboot.
