KUbuntu 12.04.1 LTS 64 bit
ASUS
Toshiba C870-18N
Working well with one exception: WLAN doesn't work out of the box.
The internal wireless card is reported as rtl8723e. To make it work, you have to hunt the Realtek website and install the drivers.
These are limited to Linux [2.6 - 3.2] (3.2 is used on Ubuntu 12.04.1 LTS).
Unless you find another way, you will have to re-install the drivers every time you update the kernel. You can also disable kernel updates by "locking package version" of the "linux-image" package with synaptic, muon, "dpkg --set-selections", "aptitude hold", etc.
If you get "Hard blocked: Yes" with "rfkill list", press "Fn + F12" (wireless key). This turns hard blocking off.
DO NOT INSTALL compat-wireless on your own but use the one "provided" by Realtek.
USEFUL INFO
I lost 20 minutes looking into the manual (not provided by ASUS, not even on their website) to find it out:
To make the boot menu appear, press F12 *repeatedly*.
Computer setup (which would be wrongly named "BIOS setup" these days) will launch if you press F2 repeatedly.
