Installation
Before installing it is necessary to modify some UEFI Settings. They can be accessed with F2 when booting.
- Change the SATA Mode from the default "RAID" to "AHCI". This will allow Linux to detect the NVMe SSD and manage its power.
- Disable Secure Boot. This may be re-enabled at a later point. See Secure Boot#Using a signed boot loader.
Dual boot
Please note that changing from "RAID" to "AHCI" can break the default Windows installation and require a complete reinstall. Usually running windows own startup repair utility however fixes this issue in most cases. Another alternative is to follow this guide.
The reinstall can be done through the Dell recovery in the UEFI if needed.
Once you used the startup repair utility or have reinstalled, Windows should boot normally in AHCI mode and without error. Then one can proceed with typical dual boot setup.
Audio
The device is equipped with 2 bottom firing speakers and 2 top firing speakers. As of Linux 6.0.x, the bottom firing speakers work out of the box, however the top firing speakers do not work. This is due to incorrect default pin output and DAC configuration: pin 0x17 is disconnected by default.
As of December 2022, a kernel patch fixing this issue has been created and merged into the sound subsystem. It is expected to be mainlined in 6.2, but may be backported to 6.1/6.0.
Until release, the patch can be applied during a custom kernel build.
Internal microphones and external microphones work without issues.
Power Management
See Hibernation for kernel parameters & initramfs configuration.
S3 Sleep is not supported. S0ix however works reasonably, loosing roughly 0.5% battery per hour. "RAID" needs to be changed to "AHCI" for S0ix to work. Without S0ix activated the laptop looses around 2% battery per hour.
NVIDIA's open source driver reliably disables the NVIDIA card. It is possible to use the proprietary driver, however as of August 2022 when it is used the NVIDIA GPU sometimes randomly turns on, drawing approximately 8W of extra power.
Fingerprint reader
See fprint.
The fingerprint reader works well if it used in one operating system only. Attempting to use the device in several operating systems results in disconnection of the device and refusal to accept fingerprints.
