Debian on Tuxedo Pulse 14

I recently ordered a few Tuxedo Pulse 14 Laptops for my lab. They come with a customized Ubuntu installation, alas we are Debian people.

Here is what needs to be done to get everything working:

Install debian bullseye.

enable non-free repository in /etc/apt/sources.lst
apt install firmware-realtek firmware-iwlwifi firmware-amd-graphics

This should get wifi working correctly. All is peachy, however we still suffer from jerky touchpad and a kernel bug which (sometimes) results in black screen after resuming from standby.

To fix this we need to add kernel parameters:

sudo vi /etc/default/grub

add the following to GRUB_CMDLINE_LINUX_DEFAULT:

i8042.reset i8042.nomux i8042.nopnp i8042.noloop xhci_hcd.quirks=1073741824

(taken from the Tuxedo help pages !)+

e voila ! Now touchpad and resume works reliably.
