DebianOn is an effort to document how to install, configure and use Debian on some specific hardware. Therefore potential buyers would know if that hardware is supported and owner would know how get the best out of that hardware.

The purpose is not to duplicate the Debian Official Documentation, but to document how to install Debian on some specific hardware.

Models covered: DELL XPS 13

2013 model

The information bellow is for 2013 model. The newer 2015 model has a different hardware configuration and is covered in another page.

Debian 8

In Debian Jessie 8.0 and up everything works out of the box except the wifi firmware which requires the non-free package to be installed.

The information bellow is for Debian 7 only.


This model comes in two options: with Windows 8 or with Ubuntu 12.04, which is called Dell XPS 13 Developer Edition. This is a very nice ultrabook which is able to run Debian pretty well. It ONLY requires one non-free firmware to fully operate (the wifi), no extra privative drivers required.

Important Note

In order to use Wifi to install, you MUST use a Debian nonfree installer. The Intel official Wifi driver is free, but the firmware required is not. You can get the non-free Debian netinst here:

From Ubuntu, just install to an empty pendrive with:

cd Downloads   # or whatever
dd if=firmware-7.0.0-amd64-netinst.iso of=/dev/sdX bs=16M

Pay attention to /dev/sdX, it is ussually sdb, but take care! (you could erase your SSD drive by accident).

Reboot and press F12 while the BIOS is loading. You have to be very fast! Then select USB boot. Now you're ready to install Debian.



Display works quite well out of the box, including brightness controls with the standard Debian kernel.


Works perfect out of the box.


Works quite well, very stable.

Be careful with the button to power it on or off, it is the same as the wifi one, see below in wifi section.


The touchpad works well with the standard kernel.

Power Management

Suspension works perfect. Hibernation works well following this guide: Hibernation/Hibernate_Without_Swap_Partition, even with an encrypted root partition.

laptop-mode-tools package is recommended, it can really save a lot of power by turning off while not using the sound card, wifi, bluetooth, usb ports... have a look at /etc/laptop-mode/conf.d/ and configure at will.

Battery can last up to 5h with the standard kernel. If you want something like 6-7h you need to install kernel 3.14 or higher. This is a known issue. Up to kernel 3.14 the linux kernel didn't handle power properly for i7 processors. See bellow.


Works well BUT you must install firmware before, and be careful not to press the wifi button which will make your bluetooth go off too.

Firmware package name is firmware-iwlwifi.


Follow SSDOptimization for SSD configurations.

Installing kernel 3.14 for better performance, higher battery life and less fan noise (optional)

Starting with kernel 3.14, linux supports advanced power management for i7 processors, making this machine more powerful, increasing battery life up to a 50%, and making less noise (installing thermald as explained bellow).

The way to proceed is:

apt-get install kernel-package git libncurses5-dev
cd /usr/src
wget -c #or use another more modern version
xz -d linux-3.14.2.tar.xz -c | tar x
cd linux-3.14.2
make-kpkg --config menuconfig --initrd --jobs 4 kernel_image modules
#in the config window shown, configure the kernel at will, I recommend to make it full preemptive and 1000Hz in the processor section
cd ..
dpkg -i *Custom*.deb

Before you reboot, it is important to configure certain variables and install some additional programs.

Installing thermald

thermald is a daemon to control fans and improve powersavings. To do this, you have to take the program from testing because it is not available on wheezy:

echo "deb-src testing main" >> /etc/apt/sources.list && apt-get update
apt-get build-dep thermald
apt-get -b thermald
dpkg -i thermald*.deb
apt-get install -f

Also, the smartmontools package is very convenient to manage the SSD:

apt-get install smartmontools
nano /etc/default/smartmontools #enable for your drive, normally 'sda'
/etc/init.d/smartmontools restart

Backlight controls with kernel 3.14 and old Xorg server

Older X servers use the first backlight control available in /sys/class/backlight which is not working anymore with 3.14. Newer X servers allow you to select what backlight control to use, but it is not the case of the X server in wheezy. In order to avoid this problem, you must disable the acpi backlight, by ensuring that video.use_native_backlight=1 is in the boot variables in /etc/default/grub:

GRUB_CMDLINE_LINUX="video.use_native_backlight=1 ....."

Remember to update-grub.

The only problem with this is that if you boot with a different kernel other than 3.14 or higher, kernel will issue an error.

Also, this kernel introduced a regression for some boards causing flickering if the brightness is not 100% or 0% (that is, in the middle). The way to resolve this is by following this guide using a low fhz (30 is good) for the led panel:
