Dual Boot Ubuntu and Vista on Dell Inspiron 1720

I just got a new Dell Inspiron 1720. A little background information on why we got this laptop... Previously we had one Desktop computer and a MythTV server/frontend and a TV in a separate room. The TV was a huge CRT TV, but not only that, the TV and couch took up en entire room. We recently got a 24" LCD for the desktop computer and decided that we could use that as our "TV" and computer and get rid of the TV room and use it for something else. We then found ourselves in the situation where one of us wants to watch TV and the other wants to use the computer so we definitely needed another computer. A laptop was the best idea as it allow us to use it as a MythTV frontend and watch TV from bed or any other place in the house. So in summary, we replaced a TV room, massive CRT TV and couch with a 17" widescreen laptop.

Unfortunately, the Dell Inspiron 1720 only comes with Vista. I thought about installing XP, but then I read about how I would have to get SATA drivers and slip stream them into the Windows XP CD and that Dell didn't have XP sound drivers for the 1720. In other words installing XP would be a huge PITA. Since I don't plan on using Windows that much anyways, I figure I can live with Vista. I will tweak it a bit anyways to get rid of its annoyances and I can live with the slightly worse gaming performance (which should improve over the next few years anyways, I suspect).

Here are all the steps I took to get Linux and Vista working on my Dell 1720.

Prepare for Linux:

  • Tell BIOS to boot from CD. Reconfigure BIOS to try booting from CD first so I don't have to remember to hit F12 while booting.
  • Reinstall Vista without Dell crap. I popped the Vista CD in the drive and booted to the CD. I deleted all 4 existing partitions (recovery partition, EISA partition, Windows Vista C: partition, and Dell media direct partition). I don't need the media direct and EISA junk. I then had to add the SATA driver from the Drivers and Utilities CD or else the installation would hang later on. I created one 120 GB partition for Vista.
  • Install Vista drivers. With the freshly installed Vista, all the drivers will be missing, most notably, the NVIDIA video drivers. I downloaded these from the Dell website along with a bunch of other drivers (sound driver required for microphone to work).
  • I downloaded Ubuntu 64-bit Live CD and burned it on another computer.

Installing Ubuntu: After selecting the first boot option from the Live CD it started to boot, but then the screen went completely blank (not just black but completely-turned-off-black. It turns out this is because the splash screen fails. X never did load. I pressed CTRL-ALT-F1 and then pressed Enter and the login prompt appeared (you may just see "running local boot scripts", until you press Enter. This is because the boot sequence steps run in parallel and the login prompt already started above). I then typed "startx" and X/Gnome loaded (I can't remember if it worked right away...I may have fiddled with the "Driver" setting in the "Device" section, by setting it to "nv"). I then installed Ubuntu and told the installer to automatically partition and use up all the remaining free space on the drive. When it came time to reboot, the screen went dead again on shut down and although I waited a long time, the computer never restarted and I had to power it down manually, then power up.

Fixing the "dead screen" on boot up and shutdown/reboot: Open up /boot/grub/menu.lst and remove all occurrences of the word "splash" and "quiet". Getting rid of the splash screen makes bootup a bit more interactive (rather than seeing a blank screen), but more importantly it allows the it to shut down properly.

Wireless/wi-fi: When ordering the laptop from Dell's website I chose the "Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)" which I had heard had better Linux support (without using ndiswrapper), but wireless still did not work out-of-the-box. I changed two things at once, so I am not sure which made it work. The first thing I did was update all packages and brought in upgrades from gutsy-updates and gutsy-proposed repositories (of course you need to plug into a wired network to do that)). I installed and upgraded all linux-restricted-modules* packages. The second thing I did was to copy and paste my WEP key, rather than typing it out by end. Now wireless works great. The Network Manager applet is so easy to use.

Wireless Update: wireless seems to lock up after a while and a process called "ipw3945" uses 100% cpu. Using the laptop as a MythTV frontend requires a stable network connection so the fact that the wireless doesn't work sucks. I've tried using the MythTv Player in Vista and it does the job but it just doesn't compare to MythTV's own frontend. I have heard that the ipw3945 module that comes with Gutsy is basically deprecated and has been replaced with the iwlwifi module from Intel. The easiest way to get it is to use kernel 2.6.24 which comes from with the next release of Ubuntu, Hardy Heron (currently in Beta, to be released in a few weeks).

Sound: Sound didn't work out-of-the-box. I installed the "linux-backports-modules-generic" package from gutsy-backports and now it works. Since Ubuntu's volume control and the button on the laptop case both control the Master volume, I used "alsamixer" to increase the PCM volume to max.

Video: My screen was stuck in 800x600 mode. Running sudo dpkg-reconfigure -phigh xserver-xorg created an xorg.conf file that gave me maximum 1920x1200 resolution. The nvidia driver doesn't work though, it complains that my GeForce 8600M GT is not supported. After updated some kernel packages in previous steps, now when I enable the nvidia driver in the "Restricted Drivers Manager" it works.

DVD: I followed these instructions for DVD playback in Ubuntu.

Hardware Sensors: I ran sensors-detect and no hardware sensors were detected.

That's about it! I'll update this page with any other tips or tricks as I find them.

Hi David,

I have an Inspiron 1720 since more or less 6 months and I am very happy with it. I also have a Dual System with XP and OpenSuse (Yes, it was a pain to configure XP but I managed). I have been very happy with my OpenSuse 10.3 (x86_64) where almost everything worked out of the box. Maybe it is worth looking into it ;)

Cheers,

Antonio

Hello,
i have a 1720, there is nothing on it beside vista home premium, office and world of warcraft game. i am experiencing very low fps like around 2fps.

I'm using an old Dell 8600 right now. I've thought about trying to do a dual boot on it to check out Ubuntu. I'm guessing it would beat Windows.

This is such a great resource that you are providing and you give it away for free. I love seeing websites that understand the value of providing a quality resource for free. It is the old what goes around comes around routine. vandoornschool.nl
