Hi Semenko,

Thank you for sharing the newest XPS13 hardware information on linux. Just wondering howz the current linux support on this machine? Does everything working properly? Many thanks!

Hey, I'm running Ubuntu 15.04 on the laptop and it "just works" (14.10 also seemed to be fine).

Issues I've noticed:

• Audio doesn't work (yet). I haven't tried debugging this at all. Probably an easy fix.
• Trackpad isn't correctly deactivated with syndaemon. This is pretty annoying, since the keyboard is a tiny bit cramped, so pressing the spacebar intermittently clicks somewhere :(

Audio and touchpad are a little weird on this system. Take a look at the ACPI tables. They're dual-mode, and the firmware decides which to present to you based on the reported OSI of the last cold boot. The audio supports HDA bus and I2S bus. The touchpad supports PS/2 and I2C. You'll get I2S and I2C if your OS reports an OSI value of "Windows 2013" to the firmware. Part of the problem is that the Linux kernel currently seems to have some issue with the audio hardware when it's in I2S mode. I'm told that if you tell the kernel to pass a value of "!Windows 2013", you'll get the legacy HDA and PS/2 modes.

I've run into the exact same issues running 14.10. I've never change acpi osi settings - is that simply a switch in grub that can be set? If so, whats the best location in grub to add this?

I've tried Ubuntu 14.04.1 LTS & Linux Mint 17.1 via their live USB and here are the results:

Ubuntu 14.04.1 LTS

1. can boot with or without UEFI
2. cannot detect wireless card
3. brightness seems not working
4. audio works fine (though only tested via turn up/down volume level using fn keys)
5. when I move the cursor around using the touchpad, it stopped to response for a short period every 20s ~ 30s, which is really annoying, don't know why this happens.

Linux Mint 17.1

mostly behaves the same as Ubuntu 14.04.1 LTS

1. cannot boot when UEFI turned on

I will try with other distros later on, hope the information helps 😃

So I tried running 15.04 (kernel 3.18) with acpi_osi="!Windows 2013"

It unfortunately didn't fix the audio issue, and causes the trackpad to hang intermittently, with:

[ 435.934715] psmouse serio1: TouchPad at isa0060/serio1/input0 lost synchronization, throwing 2 bytes away.
[ 436.448458] psmouse serio1: resync failed, issuing reconnect request

Here's a broader update of working/not working out of the box -- on Ubuntu 15.04 / Kernel 3.18. Again, these are with zero config changes. Just a stock 14.10 install -> 15.04 update.

1. Side-by-side install on UEFI with Windows 8 works from the 14.10 installer.
2. This display is beautiful, and just works
3. Audio does not work -- though I haven't debugged this at all, except for trying acpi_osi="!Windows 2013"
4. Trackpad works, but is annoyingly sensitive to accidental clicking and won't turn off with syndaemon
5. Keyboard works and is OK -- the spacebar isn't very sensitive on the left side
6. Keyboard backlight works
7. Smart keyboard function keys (brightness / keyboard light / volume) work
8. The webcam works (tested with cheese), and is located at the bottom left of the monitor
9. Wifi works
10. The extra Dell DA100 universal dongle (USB -> USB/ethernet/vga/hdmi) is detected, and ethernet works. I haven't tried the graphics components.

Have you by chance ran two boots in a row with acpi_osi="!Windows 2013" on kernel command line and still found the problem with the Audio?
Also I notice your last post has a typo with acpi_os not acpi_osi, so just want to confirm you had that right.

@superm1 -- fixed typo, thanks! I only ran one boot w/ acpi_osi -- but I'll double check & boot twice tonight.

Some updates:

After installed Ubuntu 14.04.1 LTS (or it's derivative Mint) on this laptop:

1. WiFi will not work until you installed the bcmwl-kernel-source package. (via apt-get or driver manager)
2. Seems the graphics got some problem as it's really sluggish when you dragging windows around, also, the brightness is not adjustable.
3. Keyboard will very likely to stuck on typing ( e.g. qwwwwwwerrrrrrrtt)
4. Touchpad still failed to respond constantly (I noticed an error message said 'lost connection, sending reconnect signal' during the installation process in the detail window)
5. audio works out of the box.

The strange thing for keyboard/touchpad is, when I trying Manjaro (arch based) on a live usb, it works perfectly, does this related to some kernel/x-input bug?

So I just found this thread because I've not been able to get audio work on the new Dell XPS 2013 with Ubuntu 14.10 (seems to be the case for everyone too). I did run the acpi_osi="!Windows 2013" once and that made no difference, but when I ran it twice (per superm1's suggestion) I noticed that in the sound setting - instead of it the volume bar being greyed out it was now orange and I could move the slider. However there was still no sound.

But when I went to alsamixer, now I could see a new audio device "HDA Intel PCH." So I changed to that, increased the volumes. Still no sound. Then I installed pavucontrol, opened it, and changed the ALSA plug-in container to "Built in Audio Analog Stereo." Finally - got sound

Haven't gotten much of a chance to test it out yet. However, I do notice that while the volume up and volume down keys make the sound indicator come up and modify that level, it has no effect on the actual volume. I have to change it either with the application or with pavucontrol or with alsamixer

EDIT: Rebooted after the above (ran update-manager in-between) without the kernel parameter, audio worked normally once including with the volume keys. Rebooted again without kernel parameter and no audio worked. Re-tried the kernel parameter twice and worked again.

However now I'm having garbled graphics in places, and only on the boots with working audio, and mostly involving the window titlebars/borders and right-click menus. If I maximize the window and restore to normal size then the garbled graphics involving borders clear up, and if I mouseover the options in the right-click menu then the options appear. I'm assuming this is from the kernel parameter itself

Have there been any lasting fixes for the audio issue?

I've also got the garbled graphics issue and additionally I can't seem to right click most of the time, all of my clicks being recognised as left clicks.

Also the acpi_osi flag fixes a lot of this, but I'm also experiencing the "Touchpad... throwing 2 bytes away." issue and the touchscreen doesn't work.

For the touchpad throwing 2 bytes thing - I can reliably avoid this by booting twice with the kernel parameter on and then once with it off. With that third boot, I get normal audio, no desyncing issues with the touchpad (though right-click often doesn't work), but still garbled graphics.

Can't say anything about the touchscreen, don't have one.

I've been following this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1413446 , seems like it's being actively worked on.

Yeah I'm also following that.

Is anyone getting anything close to the 15 hour battery life reported on Windows? If so, how - mine is looking more like 4 max at the moment.

With regards to battery life, running powertop gives me the following:

Of note there, to me at least, are the keyboard and mouse, which I imagine is not a problem when you let it use I2C. I'll check that when I next have a work break long enough to restart!

The other thing I notice is the i915 interrupts - anyone have any ideas on what that could be?

If got the XPS 13 with QHD touchscreen and using the acpi_osi="!Windows 2013" does at least fix the audio for me.
For the touchpad I do experience the "throwing bytes away" / "lost sync" etc. as well.

Using additional kernel-params like

i8042.reset
i8042.nomux=1
i8042.panicblink=0

which did fix it for others (different hardware though) doesn't help either :/

@semenko, I'm about to pull the trigger on the XPS13 with Dell DA100 universal dongle accessory, would you be able to confirm that the video works (either VGA / HDMI would do). Would be much appreciated!

Alright you guys...
Cause the touchpad issue really was driving me crazy like.... umfgrrrrr... I obviously invested some time ^^
The kernel-params

acpi_osi="!Windows 2013" nolapic

do fix it for me :)
"nolapic" is the one who gets rid of the "throwing bytes away", "resyncing", bla bla bla messages (though while typing this comment I just had the repeating key issue again ._.)
So far no side-effects. (btw. touchscreen is working as well... sort of... no multitouch as far is I can tell though ^^)

Additional, for the ones having the QHD-Display, you might wanna add "video=eDP-1:1920x1080@60" as kernel-param. (At least for me the tty is just to freaking small to read if it's on 3200x1800 ^^)

For reference my setup:
archlinux -> kernel 3.18.5-1

Edit:
just realized what "nolapic" even does and the outcome isn't.... mh... nice?!
Basically booting with this param you'll only have one core (processor) available which actually brings me back to the arch-wiki where a line says:

If you use CPU frequency scaling, avoid using the "ondemand" governor and use the "performance" governor when possible, as the touchpad may lose sync when the CPU frequency changes.

I've already tried that which didn't work for me :/

I've realised that the touchscreen issue is only after a suspend-resume, incidentally.

Found those two bug-reports related to the touchpad-freezes.

Thought it makes sense to throw those in here

Just pointing people to Major Hayden's blog post on this: https://major.io/2015/02/03/linux-support-dell-xps-13-9343-2015-model/

boot with acpi_osi="!Windows 2013" nolapic works perfect.
Thank you Tadly

Please make sure that you upgrade to at least BIOS A02 (or later). BIOS A02 has introduced a large number of fixes for Linux specific issues:

• Keyboard repeating
• Audio mode issues
• Needing to use acpi_osi=!Windows 2013

With BIOS A02+ and newer kernels you shouldn't need any kernel command line options applied.

Also, you will need to apply the following patches to current kernels for HDA microphone support:

This blog post from the Linux team lead at Dell has many details about which configurations and firmware versions work with which kernels, Ubuntu versions etc.:
http://bartongeorge.net/2015/04/09/4th-gen-dell-xps-13-developer-edition-available/
Seems like they solved the major issues people had.

@vincentzhezhang Thank you, I got same issues.

And, my network adapter does not work either.

@gausie did you ever fix the touchscreen suspend/resume bug?

Did you visit https://github.com/mpalourdio/xps13 ?
