This video shows me using Poky Linux on my Nokia N800 and was shot on my Nokia N73 so the quality is not very good. If you want to try Poky too, follow my guide here. With reference to this build’s problems with the N800, Richard Purdie (one of Poky’s developers) has said that:
Wifi won’t work with the released images but we have ideas to sort that in the future. Currently, if you build the image yourself you can make wifi work by copying a file in but we can’t distribute the result. On the power management front, the device will suspend/resume if you run “apm -s” but that isn’t hooked to the power button. These issues are why its marked experimental.
