This is an entry for Phoronix LCH. Feel free to comment on the Linux compatibility for the Dell L400 in this thread.

Dell L400

Description: Ultraportable laptop.
Hardware Notes: Ubuntu installs fine, but problems with ACPI; CPU-fan controls doesn't work and overheats after a while. Display adapter's direct draw doest work out of the box, therefore screen fps maybe slow. Affects Flash videos.
