Notes

As default the native screen resolution of the Latitude D620 is 1280×800, however due to the way the Intel Graphics Media Accelerator 900 functions this resolution would not be usable right away. To get it working you will need to install the 915resolution program and type in:
915resolution 5a 1280 800
This will then allow you to use the native 1280×800 resolution. However this setting will be forgotten after each boot so you will need a way to automatically run this command at every boot. Fortunately most Linux distributions come with the 915resolution program and include a simple way of achieving this. You can view our Configuring the Intel Graphics Media Accelerator 900 & 950 guide for more information.

Some versions of the D620 include the Nvidia Quadro NVS 110M. This has not been tested yet.

Some versions of this notebook have the Dell Wireless 1390 or the Dell Wireless 1490 Dual-Band wireless network card. Neither of these cards were tested.

Thanks to khadgaray for adding this:
Works fine with nv module provided by FC6 Xorg 7.1 . For dual screen i use nvidia's driver ( build 9625 )
modem - Unable to find any communication device with lspci listing :(

Microphone

Under debian, in order to use the internal microphone, create a file /etc/modprobe.d/00alsa containing the line

  options snd-hda-intel model=ref

Multiscreen

grandr works fine but you have to manually edit the virtual display space under debian, your xorg.conf file should contain a subsection

  Section "Screen"
      SubSection "Display"
          Virtual    1280 1600
      EndSubSection
  EndSection

if you want to have twice 1280×800 screens on top of each other.

Summary

As with all Intel Core based notebooks, it is recommended to use a Linux distribution with kernel version 2.6.16 or greater with the Dell Latitude D620. With a up to date kernel this laptop works well with Linux. * Unordered List Item
