Dell XPS 13 2-in-1 (7390)
The New Dell XPS 13 2-in-1 (7390) is the model released in mid 2019 in most territories and is the second iteration of the Dell XPS 13 2-in-1 series, including an updated 10th generation Intel Ice Lake processor with Iris Plus integrated graphics. It can be used like a tablet when folding the display 180 degrees backwards and includes a enlarged 16:10 FHD+ or UHD touchscreen which should work out of the box. This includes support for Wacom pen technology (tested with the "Wacom Bamboo Ink Plus").
In order for Linux to see the internal NVMe SSD, it must be changed in the BIOS from the default "RAID mode" to "AHCI mode".
Automatic screen rotation under GNOME and Wayland
Install thepackage. The screen will now automatically rotate and keyboard input will be disabled in tablet mode. If the screen does not rotate automatically, try running
$ gsettings set org.gnome.settings-daemon.peripherals.touchscreen orientation-lock false
Super+o to toggle lock state.
There are currently no drivers available for the fingerprint reader. More information:

The system defaults to Modern Standby (S0iX), which uses a lot of power during sleep. To enable S3 sleep instead, add
mem_sleep_default=deep to the kernel command line. However, now the screen will not be properly woken up on resume. To fix the screen wakeup issue, the following setting must be disabled in the BIOS settings:
POST Behaviour -> Sign of Life -> Early Dell Logo Display
Sleep/Suspend causes slow system
Issue exists with aggressive suspend settings in clock modulation settings. Setting the MSR registers manually during system wakeup using systemd is a good solution.
Run command `wrmsr -a 0x19a 0x0` to set the registers to zero after suspend. Check the registers with `rdmsr -a 0x19a `
By default, or whatever was set on Windows by Dell Power Manager, a very conservative power profile is set somewhere in memory (seems to persist BIOS resets) and starts throttling the CPU very early (2.4GHz out of 3.9GHz max on i7-1065G7).
This can be resolved using. Despite originally conceived to resolve the same issue with Lenovo laptops, it works with Dell computers.

Thunderbolt docks and external monitors
There is a known issue with the Dell Thunderbolt dock (WD19TB) that causes attached external monitors to lose the signal after anything between a few minutes and a few hours of use. A full power cycle resolves the issue temporarily. The fault is related to DisplayPort Multi-Stream-Transport (MST), which is used by the dock, and a faulty kernel implementation. The issue is being tracked here: .
Disabling MST resolves the issue, but limits the dock to drive only 1 display across all its outputs. To disable MST, add the
i915.enable_dp_mst=0 kernel parameter.
You can drive an additional display by connecting a ThunderBolt3-to-DisplayPort cable to the ThunderBolt-connector on the back side of the dock, which is passed through to the device without MST for a total of 2 external screens.
Hard crashes with IntelliJ IDEA
The Intel Ice Lake platform has a bug that causes the CPU to crash with certain compilation workloads of the IntelliJ IDEA IDE with old microcode versions.
The issue is resolved with the microcode revision 0xa0 available with the package.
