Revision as of 04:09, 24 October 2012
I have just bought a new Dell Studio XPS 13. I have not 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.
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? # CONTROL_HD_POWERMGMT=1 # # Power management for HD (hdparm -B values) # BATT_HD_POWERMGMT=255 LM_AC_HD_POWERMGMT=255 NOLM_AC_HD_POWERMGMT=255
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 do not set the option "resume" your computer does not 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
I was not able to get hibernate to work correctly b/c of my NVIDIA drivers. I am now running x86_64. I am not sure if that has anything to do with it. I did however get suspend to RAM to work.
Make sure acpid is installed and running. You can add it to the DAEMONS array in /etc/rc.conf.
Then edit these files...
/etc/acpi/actions/lm_lid.sh:
sh ~/bin/suspend
(Taken from http://www.linux.com/news/hardware/laptops/8253-how-to-suspend-and-hibernate-a-laptop-under-linux [+] with a little modification)
~/bin/suspend:
#!/bin/sh # discover video card's ID ME=`whoami` if [ "$ME" != "root" ]; then echo "You must be root!" exit 1 fi ID=`lspci | grep VGA | awk '{ print $1 }' | sed -e 's@0000:@@' -e 's@:@/@'` # securely create a temporary file TMP_FILE=`mktemp /var/tmp/video_state.XXXXXX`trap 'rm -f $TMP_FILE' 0 1 15 # switch to virtual terminal 1 to avoid graphics # corruption in X chvt 1 # write all unwritten data (just in case) sync # dump current data from the video card to the # temporary filecat /proc/bus/pci/$ID > $TMP_FILE # suspend echo -n mem > /sys/power/state # restore video card data from the temporary file # on resume cat $TMP_FILE > /proc/bus/pci/$ID # switch back to virtual terminal 7 (running X) chvt 7 # remove temporary file rm -f $TMP_FILE
This should suspend your laptop to RAM when the lid is closed.
