As default the native screen resolution of the Inspiron 640m is 1280×800, however due to the way the Intel Graphics Media Accelerator 950 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 3c 1280 800 (replace “1280 800” with “1440 900” if you have a glossy screen)
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 many Linux distributions come with the 915resolution program and include a simple way of achieving this.


The Dell Inspiron 640m laptop works quite well under Linux after using the 915resolution program. Like all Intel Core based laptops, it is recommended you use a Linux distribution with kernel version 2.6.16 or greater.

I am new to Linux. I have this Inspiron 640m notebook purchased in 2007 (first installed with Windows Vista).
Yesterday, I reformatted the hard drive and installed Linux (Ubuntu 10.10).
Everything worked fine, so far.
Have only one doubt, though.
My Wi-Fi light (on laptop) blinks.
Wi-Fi still works fine though!!
Not sure whether it is working as designed, or whether it is an indication of a serious problem!!
I'm willing to live with this issue as long as Wi-Fi works fine. But curious to know why the above phenomena.

I installed Ubuntu 7.10 (Gutsy) on my Dell 640m and everything worked (except the modem which I haven't tried yet) without any configuration on my part

Thinks I was worried about but worked “out of the box”

1440 x 900 screen res
wireless networking
media buttons on front panel
multi-card slot

The “eye candy”, wobbly windows etc is all there also.
