Apologies in advance: The original author of this entry hopes that others will improve on this preliminary effort.

Overview

Undoubtedly, this post will age quickly as 8.10 nears final release. One place for additional information is this X200 owners' thread on the Ubuntu forums.

Started off working w. Ubuntu 8.04 install using the optical drive in the X200 ultrabase. Everything went swimmingly - ethernet worked out of the box as did the optical drive itself.

Wound up upgrading to the 8.10 beta b/c of wireless troubles. See below.


Ultrabay

Handles install without any problem - note: while the machine is in the bay, it forces you to use the ethernet port on the bay.


Ethernet

Intel GigE worked out of the box w. 8.04.

8.10 beta not supporting Intel GigE hardware yet, however (see this technical overview for more details), so unless you wanna try some serious hacking I wouldn't try to do a net install of 8.10 using the ethernet until the final release. Updating the kernel for 8.10 fixes ethernet.


Wireless

Ah, the wireless.

run <lshw -C network> and sort out which wireless hardware you're working with.

For Atheros, check out this forum post

For Intel 5300 on 8.04, neither the recommended drivers (iwl5000) nor ndiswrapper did the trick. It's possible that manually-upgrading the kernel to 2.27 would do it.

On the other hand, with 8.10 the Intel 5300 works out of the box. Running <lshw -C network> again shows that it's the iwlagn driver (pre-loaded with the 2.27 kernel) that does the trick.

Fan

As reported elsewhere, the fan seems to run constantly while the machine is on under 8.04 and 8.10. Will report back if/when I find a fix in the next few days.

The fan can be made less noisy by installing the tpfand packages:

sudo apt-get install tpfand tpfand-admin

Power Mgmt

Not sure what's going on here yet, but the battery claims to have only ~3 hours of life after a full charge.

Display

With 8.10 things don't work well if you stick with the "preconfigured" xorg.conf settings: the default resolution is only 1074x768 and the highest setting that the laptop display is capable of (1280x800) doesn't even show up in the System -> Preferences -> Screen Resolution applet. To make matters worse, VGA output is a royal pain.

Here's a step-by-step guide to improve the situation if you just want to get the laptop display working properly:

  • First, make sure you've got the latest drivers for your Intel 4500MHD video card:
$ sudo apt-get install xserver-xorg-video-intel
  • Once that's over and done with, open up your xorg.conf file (note: be careful with this file):
$ sudo gedit /etc/X11/xorg.conf
  • Make the part that isn't commented out (i.e. that isn't preceded by a #) look like this:
Section "Monitor"
    Identifier    "Configured Monitor"
EndSection

Section "Monitor"
    Identifier    "HDMI-1"
    Option        "Ignore" "True"
EndSection

Section "Monitor"
    Identifier    "HDMI-2"
    Option        "Ignore" "True"
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Monitor        "Configured Monitor"
    Device        "Configured Video Device"
    DefaultDepth     24
    SubSection "Display"
        Modes "1280x800" "1024x768"
# The following line was an auto-configuration added by an external VGA projector; you might leave it out to try
# letting the system detect dimensions appropriate for whatever display you happen to use.
        Virtual    2432 864
    EndSubSection
EndSection

 Section "Device"
     Identifier    "Configured Video Device"
     Driver        "intel"
     Option        "monitor-HDMI-1" "HDMI-1"
     Option        "monitor-HDMI-2" "HDMI-2"
 EndSection


  • Note: those HDMI settings are really important because they get rid of some imaginary monitors (see this other X200 installation notes post for more details). Save your new xorg.conf file and quit the Gedit text editor. Also quit any other open programs and log-out from your session to reset the X-server and apply the new settings.
  • When you log back in, all the new settings should "just work," but don't be alarmed if things look a little weird or if the screen resolution still isn't the full 1280x800...
To make sure the xorg.conf changes "stuck" and that the resolution is set properly, open the aforementioned Screen Resolution applet: System -> Preferences -> Screen Resolution. Make sure the the box that says "Mirror Screens" is unchecked and click the "Detect Displays" button. In the little colorful diagram thingy, there should just be a big rectangle that says "laptop 12"" (or whatever portion of those words fits in the rectangle). Click on this "laptop" rectangle to make sure and activate it. Once you've clicked on it, look for the drop-down menu that says the resolution and re-set this to "1280 x 800 (16:10)." If there are other "imaginary" displays activated (there shouldn't be with the HDMI workaround in the xorg.conf file included above) use the same drop-down menu to turn them to "Off." Click "Apply" at the bottom and close the applet. Log out again to activate the new settings. If all goes according to plan, your 12800x800 display should now work like a charm!
  • Once you've got that all sorted out, go ahead and hook the X200 up to an external display via the VGA port (so far, I've only tried it directly from the laptop and not from the ultrabase). Open the Screen Resolution applet again and click "detect displays." Choose a resolution for the external display and decide whether you want a mirrored output or not. Click apply (here the system may prompt you to accept virtual display settings - say yes and confirm by typing your password), close the applet and log-out again to reset X. Once you log in, you should have an external display working perfectly.

Suspend and Hibernate

Without tweaking drivers and xorg.conf suspending through the Gnome desktop does not work - seems to be related to the problems with the display. Some people have reported no problems with Hibernate, while others...you get the idea. If you're one of those having problems, read on...

Once you've followed the instructions to get the Intel video card drivers installed (see above) Hibernate (suspend to disk) *should* work and Sleep/Suspend (suspend to RAM) *might* work (there are some conflicting reports out there). If you like, you can examine/tweak the settings in system -> preferences -> power management.


If the suspend/sleep still doesn't work, try the following work-around to get the system to recognize the sleep settings.

First, create a text file called "sleep_module" in the /etc/pm/config.d directory:

sudo gedit /etc/pm/config.d/sleep_module

In the new file, enter:

SLEEP_MODULE=kernel 

Then save this new file and exit your text editor as well as your other apps. Do a reboot and try out your freshly reconfigured suspend funciton. As before, you can examine/tweak the settings in system -> preferences -> power management.

Note: Consider using "sudo -e" for editing files.

Update: The latest updates to 8.10 (still in beta at the time of this writing) appear to include a sleep_module configuration file that includes this tweak.

Sound

(Mostly) works out of the box under 8.04 and 8.10

Worth noting the apparent problems w. Skype and Medibuntu on 8.10 - some of this appears to have been resolved recently and will hopefully make it into the final release. Sound playback within Skype still failing despite the workaround.

Camera

Works with Cheese Webcam Booth on 8.10.

VGA

"Unclaimed"
