Added a section for kernel specific configurations.
Keyboard backlight timeout on AC
On other XPS 13 models it's possible to change the keyboard backlight timeout. I'm not able to change the default 10s timeout value even with this:
By default, the keyboard backlight turns off after 10 seconds of inactivity. Some users might find this too short and annoying. The delay can be increased (or decreased) by editing this file:
After editing the value (to e.g. 30s) the value resets to 0s again. Has anybody found a solution for this?
BIOS update 1.1.9
Since the BIOS update, I get some errors, with stack dump during suspend/resume.

I can second that exact same error with 4.4.1-2-ARCH. After reading through http://en.community.dell.com/support-forums/laptop/f/3518/t/19586456 I'm starting to begin wondering if its a general hardware problem with the mainboard/powerboard. Does anyone with an XPS 9350 NOT have any of this issues with a working suspend? --Tommyfankhauser (talk) 09:47, 12 February 2016 (UTC)

Everything, including the graphics works fine, however I am having trouble to rewake up the system when the laptop lid was closed. If just the display is turning off, it always comes back. --Tommyfankhauser (talk) 12:45, 3 February 2016 (UTC)
As of this morning, BIOS 1.2.3 and latest Linux kernel 184.108.40.206-ARCH, I have no more issue with suspend/wake up. By that, I mean that I do not see the libata crash anymore on suspend/wakeup. In fact, I do not see any crashes at all. It's looking all normal. Bouh (talk) 01:01, 23 February 2016 (UTC)
I'm using the same BIOS/Kernel as you. I do see the ACPI error (namespace failure you report, but nothing else). Could it be the graphic card power management, instead? I have absolutely nothing on my kernel line (all defaults). I do load intel-ucode, and my current microcode version 0x6a. I'm not sure which version of the graphics chip you have, but the failure in intel_pm (power management of the i915) may be mitigated by "disabling" power management: have you tried putting your graphic card on always "on" power (basically disable PM):
echo on | sudo tee /sys/bus/pci/drivers/i915/0000:00:02.0/power/control
Hopefully, that will help you. Note that it's bus number 0000:00:02.0 on my machine, but it maybe different on yours (so you may have to inspect the /sys/bus/pci/driver/i915 tree). Bouh (talk) 10:48, 16 March 2016 (UTC)
Thanks Bouh, unfortunately I already have the /power/control set to 'on'. As you, I have nothing on my kernel options but intel-ucode, no power manager, etc. Do you have any kernel modules blacklisted, such as dell_* ? I currently don't have, but maybe should? --Tommyfankhauser (talk) 12:32, 16 March 2016 (UTC)
No modules blacklisted, appart from the insignificant...:
blacklist pcspkr blacklist psmouse
I'm using thermald + my own power-management scripts. I'm thinking we may have different hardware. I moved on to kernel 4.5, still no issues to report (appart from the missing ACPI namespaces). Bouh (talk) 04:31, 17 March 2016 (UTC)
PulseAudio modifying gain settings
After talking to the pulseaudio mailing list, one user, gave me the workaround. This is his answer below:
It's weird that a mic boost would affect headphone output. One explanation would be that the mic signal is fed directly to the headphones, but in that case increasing the boost should increase the noise, not decrease it. I guess it's a hardware or driver bug. To work around this, you can remove the [Element Headphone Mic Boost] sections from these two files: /usr/share/pulseaudio/alsa-mixer/paths/analog-input-internal-mic.conf /usr/share/pulseuadio/alsa-mixer/paths/analog-input-headphone-mic.conf After that PulseAudio won't touch the boost volume any more. Whenever pulseaudio is updated, the package manager will remove your modifications, so you have to redo the modifications. That's still better than having to reset the mixer after every reboot...
This is not really mentioned in the 2016 model page, but I did have some very very small icons and fonts. What I had to do was create a file and fill it with something like this:
Section "Monitor" Identifier "<default monitor>" DisplaySize 338 190 # In millimeters EndSection
This made my DPI settings similar to what they are in the Windows (240 DPI) that came with the XPS. Renatolond
In CLI, the setting mentioned above have no effect, don't they? Check this out if you want to change this: https://wiki.archlinux.org/index.php/Fonts#Console_fonts Bouh (talk) 15:16, 1 March 2016 (UTC)
Thunderbolt and XPS 15/13
I don't actually have a 13, but it seems the XPS 15 has somewhat similar hardware, at least as far as thunderbolt/USB-C is concerned. On my machine USB-C does not work without a PCI-e rescan, and the second you use the USB-C port the machine will no longer sleep with ACPI bugs on dmesg.
Is it crazy to just create a XPS 15 (2016) and Precision 5510 (which afaict is the same machine with higher-end processor options) page which just redirects here? —This unsigned comment is by BlueMatt (talk) 04:18, 29 March 2016. Please sign your posts with ~~~~!
Hi, I got exactly the same problem on my XPS 13. If I boot with USB-C adapter connected it is detectecd, if I not connects it during the boot process I need to do a rescan but if I disconnect it for the second time I got the same issue your are talking about. What is your USB-C device type your are trying to make it work? is it the Dell Multi Adatper (USB, VGA, HDMI, Ethernet)? For this one I am only able to make the Ethernet working, the HDMI is detected, my external monitor correctly detected but no signal is received on this side...

You may want to read http://ubuntuforums.org/showthread.php?t=2301071. Lots of people talking about USB-C and Thunderbolt 3. Seems display adapters work for most people with some effort, not sure about Thunderbolt 3 (which puts the USB-C port in PCIe mode), but USB-C seems pretty consistently broken in the same ways as above (I've tried it with a male A <-> C adapter and several devices, as well as my Nexus 5X which is native C).

- Thanks BlueMatt, I read it carefuly, and I saw the PCI rescan workaround, for me it is only working the first time then I got an issue where it will never been detected anymore and I need a system restart.
EDIT: Regarding VGA, everything is working well when connected, when it is disconnected if the laptop is put in sleep mode it hangs, no way to wake it up, power button led remains lighted but nothing on the screen.Belette (talk) 10:14, 30 March 2016 (UTC)
- For HDMI monitor is detected but no signal is sent so the monitor stays black, for Ethernet working if I boot the laptop with the adapter connected or if I do a rescan when I connect the adapter after the boot, but only one time...
- @BlueMatt: Regarding your question of separate articles: Exactly. It is great how this article develops, even better if contributions help users of similar/related models. Please see the extra section I created earlier as a suggestion (Dell XPS 13 (2016)#Diverting models) to account for any stub model differences that may be. --Indigo (talk) 10:10, 4 April 2016 (UTC)
- @Belette: If you look at the Bias 1.2.3 section in this discussion, the slowpath bug is caused by a Linux kernel bug that in the meantime was fixed but reopened again (). Hopefully it will be stable in 4.5.
- @BlueMatt: I love that the Arch Wiki is so detailed about special models - hence I think it really depends on how similar the XPS 12, 13 and 15 models are. I have not seen any reports on how the XPS 12 works at all, only 13 and 15. Hence, I'm positive with regard to keeping separate articles until we know how similar they really are. --Tommyfankhauser (talk) 07:45, 5 April 2016 (UTC)
I continuously had issues with the Dell WD15 USB-C dock connecting. Once every day or two the USB ports and the ethernet port would all disappear. I finally found out it was related to the broadcom WiFi adapter and connections issues. When my WiFi signal was bad (which was common at work), it would cause the issue. By blacklisting the
brcmutil kernel modules the issues totally disappeared. Lgunsch (talk) 20:04, 19 July 2017 (UTC)
I tested out reducing the tx power on the WiFi adapter, but that did not fix the issue at all. I had the tx power at less than 50%, and still had issues. Lgunsch (talk) 16:21, 2 August 2017 (UTC)
I don't see anything specifically related to multi-gesture (zoom, pinch...) on the touchpad in the Dell XPS 13 page.
I have installed xf86-input-libinput as suggested and both my touchpad and touch screen are working perfecty but I am missing multigesture.. Using this tips: https://bbs.archlinux.org/viewtopic.php?pid=1617669#p1617669 Belette (talk) 08:28, 7 April 2016 (UTC)
I tried to get this laptop to boot the Linux kernel directly, via EFISTUB, but none of the boot entries I created with
efibootmgr worked. The exact same command did work, however, from the UEFI Shell v2, as well as from systemd-boot. So I suspect that this system’s UEFI implementation doesn’t properly support passing parameters to a boot entry. For booting, you either need an UEFI boot loader (like systemd-boot), or you need to link the command line into the image, as in this article. —LucasWerkmeister (talk) 11:16, 12 June 2016 (UTC)
I am experiencing quite a lot of screen stuttering. Though I have chrome running in the background, half of my memory is still free and therefore should not cause problems even for an integrated GPU. The stuttering occurs independent from the application I use: e.g. my graphical terminal (gnome-terminal) is affected as well. Temperatures seem to be fine at about 50 to 60 °C and I load the latest intel microcode through my boot loader (systemd-boot). My X11 config file looks like this:
Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "sna" # UXA is an alternative Option "TearFree" "true" # SNA only, not needed for DRI3 EndSection
Googling the issue did not return viable results since most of them concern tearing, which I do not encounter, or recommend setting the
TearFree option to
true which I hava already done. I am using
linux 4.6.4-1 and
linux-firmware 20160516.80d463b-1 with the above
xorg.conf.d/20-intel.conf config file. I assume it to be related to at least one of the packages. -- Edh (talk) 14:46, 28 July 2016 (UTC)
AKiTiO Node Pro Thunderbolt 3 enclosure
I've found Linux (4.18.5) hard-locks on attachment of the Node Pro (Radeon HD 7970 inserted) when running the latest NVM26 firmware. Downgrading to NVM16 (see other versions on Dell's site for Intel_TBT3_FW_UPDATE_NVM16_8FDJ2_A06_4.16.00.005.exe) seems to resolve the issue.
I'm going to open a case with AKiTiO since my Dell support / warranty is expired.
