Random Ubuntu notes to install ASUS Zenbook UX31

I'm experiencing with the ASUS Zenbook (UX31) and Ubuntu.

This is a technical entry to, maybe, help others install Ubuntu on this machine.
Please read the great community documentation here : https://help.ubuntu.com/community/AsusZenbook

I did some things a bit differently.

• Use alternate USB boot (64 bit) to have an encrypted LVM
• You will need to add "nomodeset" to the grub option (video/casper/whatever not functional otherwise!)

A different /etc/default/grub to have more battery saving kernel option. Be careful here, I read and integrated some hints from the LKML. Playing with the devil here ;-)


Here are the options I use :


GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=off i915.modeset=1 i915.i915_enable_fbc=1 i915.lvds_downlclock=1 i915.i915_enable_rc6=1 i915.semaphores=1 pcie_aspm=force"

Don't forget to run

update-grub

I use slightly different options for the touchpad. Please see the script here http://pastebin.com/RdmrcwdY

I use the latest kernel (not stable) for the future Ubuntu release :
