If so, and you have a HTC Desire HD, you are lucky. XDA-Developers member called bergfex has published a native Ubuntu build for Desire HD. The following features have already been implemented:
- touchscreen (works like a touch pad in a notebook)
- two finger scrolling
- WIFI
- dragging windows
- ADB
- incoming calls
- SMS text messages
Some features are not yet fully supported: sound, hardware keys, USB host, and Firefox web browser. Original thread with instructions on how to boot Ubuntu on Desire HD is linked here.
