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 also works 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 apply for this laptop. See the dedicated pages of laptop-init-script, laptop-mode and cpufreq.
