# 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.

See Intel for details on using the Intel GPU.

### Using Bumblebee

Another way, which allows to use Optimus technology is via Bumblebee.

### 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

## 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
