Dell XPS 13 9350 & Linux

Submitted by Matthias on Tue, 01/19/2016 - 15:33

At work I recently got a new notebook for working remotely (e.g. business trips). At FIAS I had to choose a single machine for all purposes, so I chose a portable workstation (HP EliteBook). That thing was heavy, loud and not as stable to use as a dev machine with Linux as I had hoped. Now I finally have a desktop system for the day to day work, and a light notebook for remote work.

Since my employer gets all its computers from Dell I got myself a Dell XPS 13 9350. It's certainly a nice piece of hardware. Its Linux usability is quite ok at this point, though I hope it'll become even better in the coming months.

I installed Kubuntu 15.10 and updated the kernel package to 4.4 to get support for the wifi chip. Here's what doesn't work yet:

  • Wifi button (Fn + PrtScr)
  • Hibernation (it doesn't shut down in Platform mode and boots strangely in Shutdown mode)
  • ASPM (power management feature. Here's the relevant error message:
    ACPI FADT declares the system doesn't support PCIe ASPM, so disable it
    acpi PNP0A08:00: _OSC: OS supports [ExtendedConfig ASPM ClockPM Segments MSI]
    \_SB_.PCI0:_OSC invalid UUID _OSC request data:1 1f 0
    acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM

At this point I have not been able to test any Thunderbolt 3 docks/dongles. This will be important for giving presentations when traveling. The supply of interesting dongles with Thunderbolt 3 connectors is rather limited. And I don't want to order something that doesn't work. I'd be grateful for any experience there. And Apple experience might just not be relevant because their Thunderbolt implementation doesn't quite follow the original Intel spec where the UEFI firmware is responsible for bringing the hotplugged devices up and into the PCIe root.
