Debian Linux

Use Debian 13 (Trixie, currently testing)

Dual-boot with Windows:

• disable BitLocker
  • consider keeping it disabled, to allow accessing Windows partition from Linux
• shrink main partition to make space for Linux
• disable Secure Boot in BIOS for the installation (not sure it that was required)
  • re-enabling when Debian was installed worked fine

Worked out of the box:

• Wi-Fi
• Bluetooth
• graphics
• Fn controls like volume, display brightness, keyboard backlight
• webcam
• touchscreen

Audio

• requires Linux kernel 6.14 or newer
  • install linux-image-6.15-amd64 from experimental
  • for dmic quirk, see https://github.com/thesofproject/linux/issues/5380
  • https://github.com/dantmnf/zenbook-s14-linux?tab=readme-ov-file#audio
• install firmware-sof-signed, firmware-cirrus
  • cirrus is not installed by default on Debian, and it was the missing piece for me
• debugging:
  • check drivers: lspci -knn
  • check journal: sudo journalctl -k | grep -Ei "sof[-_]|cs42l43|cs35l56|hda_"
  • check alsa: aplay -l

Battery

Limit battery to 80%

• install tlp https://linrunner.de/tlp/
• sudo tlp-stat -b to check threshold
• /etc/tlp.conf to configure STOP_CHARGE_THRESH_BAT0=80
• tlp replaces power-profiles-daemon, so configure also power profiles via tlp:
  • tlp-stat -p
  • PLATFORM_PROFILE_ON_AC=balanced
  • PLATFORM_PROFILE_ON_BAT=quiet
