## System Setup

### Graphics

#### Nvidia card

Initially, both the Intel integrated graphics and the Nvidia card will be active, consuming a lot of power, so you probably want to install bumblebee and bbswitch. With this laptop, the packages nvidia, bumblebee-git and bbswitch-git are working fine.

#### Intel card

From the xps 15z, wiki page, it is reported that using the Intel card without any modifications can result in poor video performance. A quick fix that does not make things worse for the 14z is to edit `/boot/grub/menu.lst`, and append the following to the `kernel` section

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

### Power management

Classical power saving tricks should apply for this laptop. See the dedicated pages of acpid, laptop-mode and cpufreq.

First try to install pm-utils.

and see if the following command works successfully:

    # pm-suspend

Normally it should.

### Special trick for acpid

If you wish to use acpid for handling the event for plugging/unplugging the ac adapter, you should know that the script does not handle it properly. For some reason, acpi_listen does not report a second argument in AC|ACAD|ADP0 but ACPI0003:00. In `/etc/acpi/handler.sh`, you can modify these lines:

       ac_adapter)
           case "$2" in
               AC|ACAD|ADP0)
               ...

in

       ac_adapter)
           case "$2" in
               AC|ACAD|ADP0|ACPI0003:00)
               ...

If this does not solve your problem, you should be able to see what event is triggered by plugging/unplugging the laptop using acpi_listen.

### Other

USB 3.0 has not been tested but should be working. The USB 3.0 driver in the Linux kernel is located in:

    Device Drivers -> USB Support -> xHCI HCD (USB 3.0) support (EXPERIMENTAL)
    SYMBOL: USB_XHCI_HCD
