Summary of what I did.
Added the kernel parameter
sudo kernelstub -a i915.enable_psr=0 to resolve the screen flicker issue. Even better: https://bennis-blog.de/2022/05/14/resolve-display-flicker-on-the-infinitybook-pro-14-gen6-by-tuxedo/
- tuxedo-touchpad-switch (touchpad-led support – also add to startup applications)
- tuxedo-pinfix-tgl-dkms (not sure if required)
For power tuning, I installed
tlp and mostly adjusted
/etc/tlp.conf L0319: RUNTIME_PM_DRIVER_BLACKLIST="" so that runtime_pm is enabled for the nvidia card (it sometimes turned on [maybe after sleep]).
As the touchpad sometimes stops to work (mostly on login), I created a simple script that fixes the issue.
#!/bin/bash sudo rmmod i2c_hid_acpi sudo modprobe i2c_hid_acpi
Maybe: set deep sleep: (I didn’t do that because the Nvidia card wakes up after standby)
sudo kernelstub -a "mem_sleep_default=deep"
Accelerated video playback. https://wiki.archlinux.org/title/Hardware_video_acceleration
I failed to get va-api working with firefox (seems to be a known bug), but chrome is working fine following the arch wiki or https://www.linuxuprising.com/2021/01/how-to-enable-hardware-accelerated.html
For some reason `vdpau-va-driver_0.7.4-7_amd64.deb` is missing from the ubuntu repos. You can simply install it from here (debian). It enables va-api with nvidia.
[not required after 22.04] I also installed https://pipewire-debian.github.io/pipewire-debian/ with
WARNING: OPAL boot currently doesn’t work, as the SSD is power cycled on reboot.
