In some cases intermittent external monitor connection may be caused by WiFi interference with the 9350's USB-C port-particularly when the lid is closed.

You need to download the Thunderbolt update executable then extract the files from it:
The following was tested on kernel 4.16.13. The thunderbolt updates are a bit more complicated to do than the UEFI updates.

It also requires the kernel to be built with CONFIG_PCI_HOTPLUG=y.ĭoing Thunderbolt firmware updates without fwupd or Windows Hotplug support for this port requires a bug fix which landed in kernel version 4.7. Unlike the BIOS update and the Thunderbolt-nvm Linux update, this is a graphical application which must be run in a modern Windows environment (MS-DOS will not suffice) or you can attempt the procedure below (at your own risks).

In the event of devices not working correctly, ensure that you have updated to the latest BIOS (above) and Thunderbolt firmware (below).ĭell is working on a fwupd extension ( github repository) that allows updating Thunderbolt software from Linux.Īlternatively, the Thunderbolt 3 Firmware Update 4.26.11.001, A08 was released on. The USB-C port supports Thunderbolt 3, Displayport-over-USB-C and USB power delivery as well as USB 3.1. Refer to Flashing BIOS from Linux#fwupd for additional information. This might also help if your machine will not resume after suspend.ĭell provides firmware updates via Linux Vendor Firmware Service (LVFS). Store the update binary on your EFI partition ( /boot/EFI) or on a USB flash drive (fat32), reboot, and choose BIOS Update in the F12 boot menu. Should the problem persist be sure to consult the UEFI#UEFI variables section.īIOS update 1.13.0 was released on.
In case your efivars are not properly set it is most likely due to you not being booted into UEFI. For further information have a look at the Secure Boot article. However it is possible to self-sign your kernel and boot with it enabled.

The most convenient way to install Arch Linux is by disabling "Secure Boot" (Secure Boot > Disable). This is not a problem with the panel but rather a problem with the way the panels are configured for the XPS 13, as the same panel exists in the Dell's Latitseries (e7370) FHD model but with CABC disabled.
Dell has issued a fix for this however it is only available to run in Windows and for the QHD+ model of the laptop so this precaution should be taken before installing Linux, the FHD model of the XPS 13 (9350) cannot be fixed. In the XPS 13 the display panels (both FHD and QHD+) come with adaptive brightness embedded in the panel firmware, this "content adaptive brightness control" (usually referred to as CABC or DBC) will adjust the screen brightness depending on the content displayed on the screen and will generally be found undesirable, especially for Linux users who are likely to be switching between dark and light screen content. 15 CPU slowdown after resume from suspend.12.2 High noise floor when using headphones.8.2 Linux kernel 4.8 or later power savings.
