System Setup

Bluetooth

Bluetooth is functional however you may need to run

# rc.d restart bluetooth 

To get Bluetooth working properly, you may also want to add bluetooth to your daemons list in your rc.conf so the bluetoothd daemon will always start up properly.

Graphics

Dell XPS 15z has two graphics card installed, Intel integrated graphics card and Nvidia 525m card. nvidia card is using Optimus technology. Initially, both the Intel integrated graphics and the Nvidia 525m card will be active, consuming a lot of power. Unfortunately, Optimus is currently not supported in Linux by nvidia driver nor nouveau driver, so the it is easier at least for begginers to install the intel driver and disable nvidia card as described here. Another way, which allows to use Optimus technology is via Bumblebee.


The following steps outline one method for disabling the Nvidia card via acpi_call Ensure that have git installed:

# pacman -S git

Obtain a copy of acpi_call:

# git clone http://github.com/mkottman/acpi_call

Make acpi_call:

# cd acpi_call
# make

Download this script made by Ubuntu forum member sunilim. Open up the script and modify the line

insmod /home/sunil/acpi_call/acpi_call.ko

to

insmod /home/YOUR-USER-NAME/acpi_call/acpi_call.ko

Close the script, make it executable, and place it in the bin folder

# chmod +x dell.sh
# cp dell.sh /usr/bin/dell.sh

Run the script to see that it works

# dell.sh off

To make the solution permanent, open up the file /etc/rc.local and add the following line

sleep 5 && dell.sh off

Video Performance

Using the Intel card without any modifications can result in poor video performance. A quick fix is to edit /boot/grub/menu.lst, and append the following to the kernel section

kernel /boot/vmlinuz... i915.semaphores=1

X11: no screen found

This error may happen when you install nvidia driver instead of intel driver. More info here.

Touchpad

Basic functionality can be given to the touchpad, however a lack of drivers means there is no multitouch support. To enable the touchpad, execute the following command:

# rmmod psmouse; sudo modprobe psmouse proto=imps

Card Reader

To make the card reader function enter the following command:

# sudo sh -c "echo 1 > /sys/bus/pci/rescan"

This will allow it to auto mount cards until the next reboot
