Introduction
This page should give some information you need about running Ubuntu on a Dell XPS 13 7390 2-in-1 laptop.
Dell XPS 13 7390 2-in-1 is not the same model with XPS 13 7390. Dell XPS 13 7390 2-in-1 IS NOT certified with Ubuntu.
Installation gotcha's
- Dell does not preload Ubuntu with the machine, this model is not certified by Canonical.
- The system firmware is not published on LVFS, the user need to download the exec files from Dell support website.
XPS 13 7390 2-in-1 is using Intel Ice Lake processor, Ice Lake is first supported by 5.3 Ubuntu generic kernel with 19.10 or linux-oem-osp1 kernel with 18.04 LTS.
- The default BIOS setting is designed for Windows, SATA mode needs to be set to AHCI for Linux
- To do this while keeping dual boot: run msconfig, edit the default Windows 10 boot profile in the second tab, "Boot", select "Safe boot" in the "Boot options" box
- Reboot into BIOS settings (F2), set boot mode to AHCI instead of RAID
Reboot into Windows, run msconfig, and disable "Safe boot" in Boot > Boot options

The BIOS version 1.0.6, 1.0.9, 1.0.13 (or newer) is not compatible with Linux. intel-lpss driver conflicts with write-combining MTRR region - https://bugs.launchpad.net/bugs/1845584

It takes long time to wake up from s2idle on Dell XPS 7390 2-in-1 - https://bugzilla.kernel.org/show_bug.cgi?id=205119
Known issues
Doesn't wake up from suspend on BIOS 1.0.13 with up-to-date 19.10 (2019-12-01) – https://askubuntu.com/questions/1183716/ubuntu-19-10-on-dell-xps-13-2-in-1-7390-suspend-problem
Workaround: add pcie_aspm=off to kernel cmdline (add to GRUB_CMDLINE_LINUX in /etc/default/grub, and run update-grub) – this will negatively impact power consumption
- Icelake IPU4 webcam doesn't work (see below)
- Brightness auto-adjust is too aggressive; workaround: disable auto-adjust and adjust manually
Log is spammed by sensor hub messages on up-to-date 19.10 (2019-12-01) – https://bugzilla.kernel.org/show_bug.cgi?id=204837 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1818547
- Workaround: silence these messages with a /etc/rsyslog.d/10-hidsensor.conf with contents below and restart rsyslog (sudo systemctl restart rsyslog)
# Disable runaway messages :msg, contains, "hid-sensor-hub 001F:8087:0AC2.0003: hid_field_extract() called with n (192) > 32!" stop
Camera
Intel Icelake integrated the IPU 4th Generation Gen IPU with on-die MIPI interface, which is not supported by Linux.
The current linux mainline 5.3 supports only Intel Image Processing Unit 3, tested on Kaby Lake platforms (U/Y processor lines). Since the IPU4 contains both scalar processor and vector processors, the lowest layer of the software stack is the firmware that runs on those cores. The IPU4 is a single PCI device but logically it is comprised of two independent systems: the input system (ISYS) and the processing system (PSYS). As such, each has its own driver.
The Linux camera stack is heavily reusing Android and keeps IPU FW, Kernel drivers, libiacss, and advanced 3A libraries exactly same as Android. An alternate Linux camera HAL has been introduced into the stack to provide a unique interface for upper-layer software. Specific in Yocto Linux, GStreamer is required as the multimedia framework where a camera source plugin for IPU4 will be needed.

Joule IPU4 drivers - these drivers are the only public IPU4 drivers as of 2019-12-01, but they need non-trivial porting to build against 5.3
