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 you need to install the intel driver and disable nvidia card.
See Intel for details on using the Intel GPU.
Disabling Nvidia card with acpi_call
The following steps outline one method for disabling the Nvidia card via acpi_call. This will only disable the card. If you wish to use it, use Bumblebee instead. Ensure that have git installed:
# pacman -S git
Obtain a copy of acpi_call:
# git clone http://github.com/mkottman/acpi_call
# cd acpi_call # make
Download this script made by Ubuntu forum member sunilim. Open up the script and modify the line
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
Another way, which allows to use Optimus technology is via Bumblebee. This program is available from AUR and even provides it's own drivres for Nvidia card, available from AUR as well.
Boot time errors
If you encounter boottime errors with intel, add
intel_agp modules to the
MODULES section in
# MODULES="intel_agp i915"
Then regenerate the initramfs:
# mkinitcpio -p linux
X11: no screen found
This error may happen when you install nvidia driver instead of intel driver. More info here. Basic solution is to uninstall NVidia driver and install
Touchpad and Keyboard
As of kernel 3.6, out of the box the keyboard works perfectly and the touchpad works with basic functionality (no multitouch). A driver has been written to enable full multitouch support but has not yet been included in the mainline kernel. To use this driver, you will need to use a kernel with the driver built in. There are two kernels in the AUR that include this driver: linux-xps15z and linux-mainline-dellxps.
To make the card reader function enter the following command:
# echo 1 > /sys/bus/pci/rescan
This will allow it to auto mount cards until the next reboot
