Asus Q408UG Laptop Linux notes

gistfile1.txt

- Keyboard doesn't work by default
  - add "i8042.reset i8042.nomux" to KCL in grub on install and on first boot
  - add above to 
- GPU works with Prime... 
  - Install nVidia proprietary
  - Try "sudo ubuntu-drivers autoinstall" - especially on Kubuntu which has a broken Software Manager proprietary drivers tab
  - Set up Prime for ondemand
  - When running a command that should use the GPU, prefix with:
    "__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia"
- "Howdy" works for IR cam login
  - Ubuntu: follow instructions on GH project to install from PPA : https://github.com/boltgolt/howdy
  - IR cam is /dev/video2, color cam is /dev/video0
  - For KDE to see Howdy's PAM module in the lockscreen:
    - sudo chmod -R 755 /lib/security/howdy
  - sudo howdy config
    - no_confirmation = true   # needed for KDE / Kubuntu if it hangs during login or screen lock
    - device_path = /dev/v4l/by-path/pci-0000:05:00.3-usb-0:3:1.2-video-index0
    - max_height = 360         # (no reason to truncate to 320)
    - dark_threshold = 75      # may need to play with "howdy test" to find best threshold
    - capture_failed = false
    - capture_successful = false
- Psensor (and other sensor setup)
  - Tctl is the best sensor for platform temp
- Ditching Windows
  - ASUS is using a standard Win10 install
  - MyASUS tool (avail. from Asus) provides all vendor-specific services like charge control
  - MyASUS is used to register for warranty, so it may be worth it to use Windows briefly to do that and update BIOS
  - Firmwares:
    - BIOS is the only fw provided by ASUS - no separate ME or other peripheral firmware
    - BIOS can be flashed from BIOS setup - go to Advanced mode (F7), Advanced menu, ASUS EZ Flash 3 Utility
- Charge limiting - create this file then enable / start service to limit to 80%:
  /etc/systemd/system/battery-charge-threshold.service
