If you don't have a better alternative to getting the install to work, don't bother flaming.

Introduction
This page should give you all the information you need about running Ubuntu on a Dell XPS 15z laptop. XPS 15z works fine with Ubuntu, read this whole guide before start installation.
Installation gotcha's
Boot installer with acpi=off (to access boot options press any key when the purple screen with human=keyboard appears.)
- USB installation: booting with an USB 2.0 storage on the USB 3 slot works to direct installation.

* The HDMI is physically connected to the nVidia card -- by manually changing the xorg.conf, it is possible to start X on the nVidia card only, getting the HDMI video (at the cost of inactive main laptop screen and the Mini Displayport output).
Hardware
Optimus / Graphics cards
Bumblebee and nvidia-current driver
With 2GB NVIDIA GeForce GT 525M Graphics Card with Optimus installing nvidia-current drivers from restricted drivers causes the loss of compositing. Moreover running nvidia-xconfig crashes X on the next reboot (fix it with sudo rm /etc/X11/xorg.conf and reboot). This happens because you need Bumblebee to make it work, more explanations follow the suggested procedure.
More information about this subject can be found in Bumblebee.
As an example, using Bumblebee, it changes battery rate from 1900+ to around 1600 for me (verwilst). The current rate (with disconnected charger) can be tested using:
grep rate /proc/acpi/battery/BAT0/state
9 in 1 card reader
Download the drivers at post #10 http://ubuntuforums.org/showthread.php?t=1718934 uncompress the file, open a terminal and cd to the uncompressed directory and type
# make
and then
# sudo make install
reboot
Trackpad
Full multi-gesture trackpad usage does not work at this moment.
A latest kernel update seems to bring basic functionality out of the box, therefore the following procedure won't be necessary.
It is however possible to get basic mouse functionality with the following command:
# sudo rmmod psmouse; sudo modprobe psmouse proto=imps |
( Or use proto=bare or proto=exps ).
To make this persistent, add the following line to a file in /etc/modprobe.d/ (/etc/modprobe.d/options.conf could be an option, but modprobe parses all the files in that directory):
options psmouse proto=imps |
Fix various glitches
The following fixes are needed to boot correctly after installation. Otherwise the laptop will freeze before login screen.
For a first boot hit e on the first option while on grub screen and add the following commands to the boot sequence just after "quite splash".
pcie_aspm=force acpi=noirq i915.semaphores=1
To make it persistent add pcie_aspm=force acpi=noirq i915.semaphores=1 to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub.
Then run the following command:
# update-grub |
And reboot. This fixes ACPI issues, lowers power consumption and 1-2 second regular freezes of your video card.
Wireless connection
Wireless connection can be seldom hard to bound or discontinue, it depends on power management settings.
A script named wireless and located in /usr/lib/pm-utils/power.d fires PSP when the pc is running on battery. If you want to override this setting create an empty file named wireless into the folder /etc/pm/power.d/.
In some cases PSP can be triggered also by other events like stand-by. If this is your case add the following lines to /etc/pm/power.d/wireless
#!/bin/sh |
/sbin/iwconfig eth1 power off |
USB 3 mass storage
If your USB 3.0 mass storage device is not recognized, even for fdisk or lsusb, you can try blacklisting the USB Attached SCSI module. Add the following line to /etc/modprobe.d/blacklist.conf
blacklist uas |
