Here are some notes from my installation of Ubuntu Gutsy 7.10 on Dell XPS M1330.
Dual core processor correctly recognized, frequency scaling works ok except after suspending to memory. When resuming, the second core runs always at the maximum frequency.
You can read the temperature of each core by loading the coretemp kernel module and run:
Remember to add coretemp to /etc/modules .
Nothing to say here.
My laptop is equipped with a GeForce 8400M GS card.
Install nvidia-glx-new, nvidia-kernel-common, linux-restricted-modules .
Ubuntu recognized the GeForce without any intervention. 3D works perfectly (tested with armagetron).
Run nvidia-settings to tune the parameters of the graphic card.
strawks reports that users with Intel GM965 Graphic Card experience stability problems under Xorg (see https://bugs.freedesktop.org/show_bug.cgi?id=11847)The external VGA port is almost unusable: when you plug the power adapter, some fuzzy lines appear on the external VGA screen/projector. Thanks Dell for putting the power port next to the VGA port. In the beginning I thought my unit was the only defective one, but a quick search on Google showed up a lot of people who experience the same problem.
TBD: test HDMI output
Make sure the SATA controller in the BIOS is set to AHCI. Ubuntu has no problem to recognize the controller and the hard drive. I also decided to enable the ‘quiet mode’ for the hard drive in the BIOS at the price of some performance (or so the manual says). Output of hdparm -t -T /dev/sda:
Timing cached reads: 7276 MB in 1.99 seconds = 3648.61 MB/sec
Timing buffered disk reads: 160 MB in 3.02 seconds = 53.06 MB/sec
Works out of the box. Typical features found on Synaptics touchpad (i.e. scrolling, double tap) are enabled by default.
My laptop is equipped with an Intel PRO/Wireless 3945ABG. It works by default with ipw3945 which is part of linux-ubuntu-modules-2.6.22-14-generic package. Driver is rock solid.
Packet injection is available through the experimental module ipwraw. This one allows raw packet Tx/Rx with the Intel 3945ABG adapter, it’s raw mode only and can’t be used for normal connections to the Internet. Somebody at http://homepages.tu-darmstadt.de/~p_larbig/wlan/ added wireless extensions to this driver and made it work with aircrack-ng.
Jester de Jong reports that his laptop is equipped with Intel PRO/Wireless 4965 AGN and it works out of the box too with Ubuntu 7.10, but not on N-speed. The maximum speed he can get so far is 54 Mbit/s. Apparently for now there is no driver for Linux that supports N-speed (300Mbit/s).
Supported by the tg3 kernel module. Works out of the box.
Hot keys for changing the volume, reproducing media, ejecting dvd, changing brightness all work out of the box.
This laptop is equipped with an Intel HDA audio with a Sigmatel STAC9228 codec. Output works fine by default, but the integrated digital microphone does not.
A patch is available on Ubuntu’s bug tracking system and some nice guy at Ubuntu generated an unofficial kernel module which already contains the patch.
Download http://people.ubuntu.com/~rtg/linux-backports-modules-2.6.22-14-generic_2.6.22-14.11UNRELEASED_i386.deb and install it with:
dpkg -i ./linux-backports-modules-2.6.22-14-generic_2.6.22-14.11UNRELEASED_i386.deb
After installing the package open a shell as root and run alsamixer:
- Go under Digital Input Source and select Digital Mic 1 instead of Analog Inputs
- Press F4 to change the view to Capture, then crank up the volume of Capture 1, Capture 2 and Digital
- Press ESC to exit alsamixer
If you have a WLED screen (like me), you get a 0.3mpx webcam. It works with all V4L2 compatible programs after installing latest linux-uvc. Here are the steps I followed:
- apt-get install build-essentials
- svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk linux-uvc
- cd linux-uvc
- make install
- modprobe uvcvideo
- Remember to add uvcvideo to /etc/modules
If you want to make video calls using Skype, you must install Skype 2.0 beta. Works perfectly for me.
Jester de Jong reports that this webcam worked out of the box for him with the uvcvideo driver included in Ubuntu 7.10.
Feedback on the 2mbpx webcam which ships with the CCFL screen is welcome.
Multiple card reader
Secure Digital cards can be accessed out of the box. The SD reader is supported by the sdhci module which ships with the stock kernel.
Controlling fan speed
Install the i8kutils package and load the i8k module with:
modprobe i8k force=1
You can control the fan speed by running i8kmon and see the current temperature and fan speed by doing:
which will return in order:
- BIOS version
- serial number
- CPU temperature
- fan status
- fan rotation speed (only on some models)
- ac power status
- volume buttons status (not the multimedia buttons)
External USB modem
Works out of the box. Install gnome-bluetooth, bluez-gnome and gnome-vfs-obexftp if you want to be able to navigate inside the memory of your mobile phone (it must support Obex file transfers, almost every mobile does nowadays) using nautilus.
To associate a mobile with your laptop, search for the laptop from the mobile, try to connect to it and enter a PIN. When a connection is attempted, the laptop will prompt you for the secret PIN that you entered on your mobile.
To send files from mobile to laptop:
Run Applications / Accessory / Bluetooth File Sharing
A new icon will appear in the tray bar. When a file is sent to the laptop, a prompt will appear.
To send files from laptop to mobile:
Open nautilus and right click on the file, choose ‘Send to…’ and choose Bluetooth (OBEX Push) in the drop-down menu.
TBD: GPRS/UMTS connections via Bluetooth
If your Dell XPS m1330 has a fingerprint reader, install the thinkfinger (http://thinkfinger.sourceforge.net/) package. A nice howto for Ubuntu with repositories and step-by-step instructions is available at https://wiki.ubuntu.com/ThinkFinger .
My laptop is equipped with a 85 WHr 9-Cell Li-Ion battery (the largest available, at least at the time I placed the order).
The battery doesn’t follow the flat shape of the laptop. It provides an alternative base for the bottom of the rear of the laptop and slightly lifts the rear part up. This way the keyboard is gently inclined and very comfortable to use. The downside of this is that you lose stability when holding the laptop on your lap (!) and after some time it starts to hurt your legs.
So you face the dilemma: why would you want to have a longer battery life if this comes at the price of hurting your legs when travelling? Why would you need to have a bigger battery just to keep the keyboard inclined when sitting at the desk, where you don’t need battery power? :)
The laptop can run on battery power for about 4 hours / 4 hours and 20 mins with WiFi and Bluetooth disabled.
The battery life goes down to about 3 hours / 3 hours and 20 mins with WiFi and Bluetooth enabled.
The screen brightness doesn’t seem to make much difference on power consumption, this is probably because of the White Led LCD screen. If your laptop has a traditional CCL LCD screen, things could be different. Like always, when talking about battery life YMMV.
Misc: suggestions for saving power
These are some generic suggestions that will work with most laptops, not only Dell XPS m1330.
Add options usbcore autosuspend=1 to /etc/modprobe.d/options
Run /usr/bin/hal-disable-polling –device /dev/scd0 to allow the CD/DVD rom to spin down after a while.
to /etc/sysctl.conf .
Add /sbin/iwpriv eth1 set_power 5 to /etc/rc.local and make sure that it gets executed at boot time.

Kudos to Philip Langdale who started this madness on his blog at http://intr.overt.org/blog/?page_id=56 with an article on how to run Slackware on Dell XPS m1330.
