I have just bought a new Dell Studio XPS 13. I haven't been able to find any information for installing Arch Linux on this machine. It is a very nice looking laptop, and runs fast and smooth. I have had a successful install (32-bit only, 64-bit). I still have a few things to get working, like the Bluetooth, and media buttons.

System Specs:

  • Processor
    • Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz
  • RAM Memory
    • 4 GB DDR3
  • Webcam
    • 2.0 Megapixel Webcam
  • Hard Disk
    • 320GB SATA 7200 rpm HDD
    • 500GB SATA 7200 rpm HDD
  • Video Card
    • NVIDIA 9400M
    • NVIDIA 9500M (9400M G + 9200M GS)
  • Wireless
    • Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller
    • Atheros Communications Inc. AR928X Wireless Network Adapter

The basic installation performs normally, with the core cd, also the wireless modules ( Atheros wifi card ) were well recognised and worked out of the box.

Video Card

Nvidia 9500 M (9400+9200)

It works well with this /etc/X11/xorg.conf, the really important feature is Busid "PCI:3:0:0". There are also some touchpad configuration with two-finger scrolling and tapping.

Power Management

HDD important issue

With the Western Digital hard drive (not SSD), there is an important issue: using the APM (Advanced Power Management) there are too nomerous spin-down, that can damage the hard drive [1]. To confirm this issue you have to install smartmontools:

# pacman -S smartmontools

And you have to run multiple times this command (once in a minute for like 5 minutes):

# smartctl -a /dev/sda|grep Load_Cycle_Count

If the number under Load_Cycle_Count is increasing in a small amount of time (1 or 2 in a minute) you have this issue.

The problem is easily solvable using laptop-mode-tools. In your /etc/laptop-mode/laptop-mode.conf you have to set:

# Should laptop mode tools control the hard drive power management settings?

# Power management for HD (hdparm -B values)

This disable all power management systems of the hard drive cause a light heat up (maybe). The same behaviour can be obtained running this command:

# hdparm -B 255 /dev/sda

the 255 number is the power-management level, in a range of 1-255 where 1 is maximum powersaving and 255 powersaving disabled. However setting the value to 253 causes a lot of spin-down. Setting the spin-down feature (it parks the heads away from disk) however can save hdd in case of fall.

Hybernation - Suspend

This feature works very well, the only thing you have to set is your /boot/grub/menu.lst , if you don't set the option "resume" your computer doesn't resume after hybernation, so add resume=/your/swap/partition like in this example:

title  Arch Linux
root   (hd0,4) # It depends on your device
kernel /boot/vmlinuz26 root=/your/root/device ro resume=/your/swap/partition
initrd /boot/kernel26.img
