I finally upgraded my server TAD1 to ubuntu Linux. Some testing is still needed, but the first impression is very nice: easy installation, gnome 2.8 and evolution 2.0.2 by default. Do yo really need anything more to start working? 1280 ppi resolution was picked on by default.
I’ve found this page with a lot of good tricks to run ACPI, suspend S3 and a lot more with my laptop, latitude d600, the same that Carlos García (KaL)have bought these days. I will try them as soon as i can.
