Hey! Been on Linux Mint for a while now and having some teething issues.

1. Restarting / Shutdown results in laptop restarting with no backlit keyboard. Need re-instated from the function key on boot.
2. Scaling to 125% randomly will default back to 100% when waking laptop from suspend.
3. Laptop screen remains off after pressing power key from suspend mode, forcing a hard reset.

The only modifications I've done is adding "i915.enable_psr=0" to the config as my laptop's intel GPU was causing the system to freeze.

Specs below and neofetch attached.

Are you missing any intel firmware?:
Code:
# dmesg | grep -i firmware

Do you have the latest firmware installed? This can be checked by having at look at what's in the repos and upgrading to the latest there, but also you can have a look in your /lib/firmware/i915 file compared to what's in: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915. If there is more recent firmware at kernel.org, it's possible to just copy it to your local /lib/firmware/i915 directory.

Can you control scaling with xrandr? If that's possible, you can set xrandr to size the display at bootup. Can't help yet on the backlight.
