ACPI Suspend and Hibernate

Both Suspend and Hibernate work reliably with some changes to /etc/default/acpi-support. Here are the steps, tested and working on both Dapper and Edgy. On Ubuntu Jaunty (Alpha 4) the Suspend/Hibernate have been tested successfully out of the box (meaning without configuring anything, just on a clean Jaunty install).

  1. First, restore the default /etc/default/acpi-support by running sudo apt-get --reinstall install acpi-support.

  2. Open /etc/default/acpi-support and make the following changes:

    1. POST_VIDEO=false

    2. SAVE_VIDEO_PCI_STATE=true

    3. HIBERNATE_MODE=platform

    4. Save your changes.
  3. Open boot/grub/menu.lst and look for the line that starts with # defoptions=quiet splash

    1. Do not uncomment this line! Leave it commented.
    2. If you see acpi_sleep=s3_bios, or any acpi_sleep=blah option on the commented defoptions line, remove it.

    3. Again, do not uncomment this line! It should look something like # defoptions=quiet splash  when you're done.

    4. Save your changes.
    5. Run sudo update-grub. Don't forget this.

  4. Do a full reboot of your machine. Log in to your desktop and then suspend the machine. If there are problems with coming back from suspend the first time, ignore them, reboot, and try again. Second time is the charm and you should have no further problems.

Step one doesn't restore the default acpi-support file. ~StevenBell2 Worked sometimes for me in Feisty, doesn't work for me on Gutsy. ~StevenBell2

Built-in Front Panel Microphone

Most Dell Latitude D620s have both a microphone jack and a built-in microphone. If you have the Intel High Definition Audio chipset, ALSA sometimes does not detect the built-in mic by default.

To see if this is the case, open your Volume Control, click Edit->Preferences, check the Input Source, Capture, and Capture Mux options, then click Close. Next, click the Options tab and look at the contents of the Input Source dropdown. If there is no item named "Front Mic", ALSA has missed your device and will never use your mic jack!

To fix this, add the line...

  • options snd-hda-intel model=ref

...to the end of the file /etc/modprobe.d/alsa-base, then reboot your machine. "Front Mic" should now be an available input source.

It seems to work out of the box with Jaunty (Alpha 4), however the sound is really low... You have to talk really close to the microphone.

ALPS GlidePoint Touchpad

Note: This is not needed for Ubuntu 7.04 (Feisty)

Some (if not most) D620s come with an ALPS Glidepoint touchpad. This touchpad uses the "synaptic" xorg input driver, but has slower default acceleration settings than Synaptics-branded touchpads.

To see if you have an ALPS Glidepoint touchpad, run...

  • cat /proc/bus/input/devices | grep ALPS

...and watch for output. If you see something like "N: Name="AlpsPS/2 ALPS GlidePoint"", you probably want to make your touchpad a bit faster.

To do this, run sudo gedit /etc/X11/xorg.conf. Find the InputDevice section containing a reference to the synaptics driver, and add the options as demonstrated below:

Section "InputDevice"
   Identifier   "Synaptics Touchpad"   # Don't change this from whatever value you have set already.
   Driver       "synaptics"
   Option       "SendCoreEvents"        "true"
   Option       "Device"                "/dev/psaux"
   Option       "Protocol"              "auto-dev"

   Option       "LeftEdge"              "130"
   Option       "RightEdge"             "840"
   Option       "TopEdge"               "130"
   Option       "BottomEdge"            "640"
   Option       "FingerLow"             "14"
   Option       "FingerHigh"            "15"
   Option       "MaxTapTime"            "180"
   Option       "MaxTapMove"            "110"
   Option       "ClickTime"             "0"
   Option       "MaxDoubleTapTime"      "100"
   Option       "EmulateMidButtonTime"  "75"
   Option       "VertScrollDelta"       "20"
   Option       "HorizScrollDelta"      "20"
   Option       "MinSpeed"              "0.60"
   Option       "MaxSpeed"              "1.10"
   Option       "AccelFactor"           "0.030"
   Option       "EdgeMotionMinSpeed"    "200"
   Option       "EdgeMotionMaxSpeed"    "200"
   Option       "UpDownScrolling"       "1"
   Option       "CircularScrolling"     "1"
   Option       "CircScrollDelta"       "0.1"
   Option       "CircScrollTrigger"     "2"
   Option       "SHMConfig"             "true"
   Option       "Emulate3Buttons"       "on"
EndSection

Save the file and close your editor.

Warning: Don't change the Identifier value of your touchpad device in xorg.conf unless you know what you're doing! Failing to change it properly could cause X to crash at startup, leaving you with no graphical environment.

Finally, log out. At the login screen, press CTRL-ALT-BACKSPACE. Your new touchpad settings should now be in effect.

Note: (ArnaudQuette) since "SHMConfig" is set to "true", one can use GUIs to do the same without having to restart the X server. simply install qsynaptics (Ubuntu) or ksynaptics (Kubuntu). I might check to make a gsynaptics someday.

Fingerprint reader

This works, in fact, for any laptop using a "Thomson Microelectronics Fingerprint Reader". To check your fingerprint reader type:

sudo lsusb

For Ubuntu Hardy (at least since July 27 2008) You just need to install the following packages: thinkfinger-tools libpam-thinkfinger.

sudo apt-get install thinkfinger-tools  libpam-thinkfinger 

After this, you need to acquire a fingerprint sample to register your user:

  1. Acquire the fingerprint with the command

sudo tf-tool --acquire

It will ask for your fingerprint 3 times (or more if there are failed scans).

  1. Test your fingerprint

sudo tf-tool --verify

It will tell you if the scan matches the one acquired above.

Finally, edit the file /etc/pam.d/common-auth by adding the following line BEFORE any other:

auth    sufficient      pam_thinkfinger.so

That's it; you are done. Upon your next reboot you will have your fingerprint reader enabled and available any time you needed to type your password.

For more information, read the original article: https://wiki.ubuntu.com/ThinkFinger

Notes

* on Feisty (ArnaudQuette):

  • wifi / sound / touchpad / multimedia keys work fine
  • the only thing left to be done is to install i915resolution and call "sudo /etc/init.d/915resolution start" to get the right native resolution (1280 x 800 for me).

* Wireless NIC ipw3945 requires restricted-modules package to be installed.

@Daniel Danek Szymanek

I had to install Intel Graphics driver to install Ubuntu. Ubuntu detect Ethernet wired connection but the wireless driver didn't work. I had to use nadiswrapper but not from repository. I compiled ndiswrapper from source.


I had some problems with wireless that from some reports seemed to be because of a IRQ conflict with the NVidia. Linux 2.6.20 seems to have a fix for that. I updated to Feisty which had that version of the kernel and it worked. I wouldn't necessarily recommend the Feisty upgrade, but if you can get 2.6.20 it should help.
