In this page I collect some useful resources I have found and that have helped me install Mint on this Ultrabook and fix some of the issues.
I used this site as a guide How to dual-boot Linux Mint 13 Cinnamon/MATE and Windows 7, but sadly it didn't work completey as planned.
I had read elsewhere that the UX31 models kept randomly freezing and I experienced the same. Installation of the liquorix kernel fixed this.
After much searching, it seems that fixing most of the Fn keys is not so difficult, but the F5 and F6 keys (monitor brightness) still don't work. My workaround was simply to have the Brightness and Lock "app" in my taskbar.
To make the rest of the Fn keys work:
sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update && sudo apt-get install dkms sudo dpkg -i asus-wmi-dkms_0.2_all.deb sudo reboot
The instructions from the Ubuntu Community tell us to use the 3.4.7 kernel, but everything works fine with the 3.4.0-8.dmz.1-liquorix-amd64 kernel, which apparently is a modified 3.4.8 kernel.Out-of-the-box situation is pretty bad. No right-clicking, no middule button, no left-click and drag... Installing liquorix also allowed for left-click and drag, which was not enabled before, but the rest remains unusable.
Create a file "/etc/X11/xorg.conf.d/99-middle-mouse-button.conf" and copy into it:
Section "InputClass" Identifier "My Synaptics options" MatchDriver "synaptics" Option "ClickPad" "true" Option "EmulateMidButtonTime" "0" Option "SoftButtonAreas" "66% 0 82% 0 33% 65% 82% 0" EndSection
To get everything to work properly, xorg-edgers comes to the rescue again! Once the repository has been added (see Function keys, above) just install one more packed
sudo apt-get install xserver-xorg-input-synaptics
Done!
