System Setup

Hangs on boot

Sometimes when boot the laptop with the default kernel it would hang at uevent detection, to prevent this from happening add kernel boot param nox2apic edit /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="nox2apic"


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 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

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

Using Bumblebee

Another way, which allows to use Optimus technology is via Bumblebee. This program is available from AUR and even provides it's own drivers for Nvidia card, available from AUR as well.

Video Performance

Using the Intel card without any modifications can result in poor video performance. A quick fix is to edit boot options of your boot loader and append the following to the kernel parameters:

# i915.semaphores=1

Boot time errors

If you encounter boottime errors with intel, add i915 and intel_agp modules to the MODULES section in /etc/mkinitcpio.conf:

# 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 intel driver.

Bluetooth

See Bluetooth.

Touchpad and Keyboard

Touchpad is fully supported in kernel 3.9 or later. Make sure to install xf86-input-synaptics as well as a program such as synaptiks so that you can customize all of the features.

Keyboard is not working

In case your keyboard is not working after installing Arch, or after upgrading older installation add this to your kernel line:

# acpi=noirq

As mentioned above, this problem shouldn't occur in new installations, although may in some cases of customized installs.

Card Reader

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
