=== Boot options ===

Add to the grub boot line the following options :

|| acpi=noirq ||

To keep these option edit the grub command. Execute this in a terminal :

|| $ sudo gedit /etc/default/grub ||

And modify the line :

|| GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" ||

It to obtain this line :

|| GRUB_CMDLINE_LINUX_DEFAULT="acpi=noirq quiet splash" ||

Then, save, close, and back in the terminal, execute :

|| $ sudo update-grub ||

Now, when you will restart, it should be great.

=== 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.

The Bumblebee stable PPA and more information about this subject can be found in [[https://launchpad.net/~bumblebee/+archive/stable|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
}}}

===== Installation on 12.04 =====
Add bumblebee ppa, reload, check your update and install bumblebee. Finally add your $USER (replace by your username to the group bumblebee :

|| $ sudo add-apt-repository ppa:bumblebee/stable ||
|| $ sudo apt-get update && sudo apt-get upgrade ||
|| $ sudo apt-get install bumblebee bumblebee-nvidia ||
|| $ sudo usermod -a -G bumblebee $USER ||

Now restart, and check your configuration :

|| $ glxspheres ||
|| $ optirun glxspheres ||

And compare the fps... If you need to use the nvidia video card, launch your application with 'optirun' at the begin of the command line.

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 ||

== 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 ||

Anyway power management can be always manually turned on or off by giving the following command on terminal

'''sudo iwconfig''' ''your lan name'' '''power off''' or '''power on'''

== 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 ||

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=noirq (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.

Optimus / Graphics cards

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.

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

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

Anyway power management can be always manually turned on or off by giving the following command on terminal

sudo iwconfig your lan name power off or power on

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
