Just thought I'd share my experience with the new S440 offering from Lenovo.

Hardware specs;

4th Gen Intel Core i5-4200U Processor (3MB Cache, up to 2.60GHz

14.0 W HD+ (1600 x 900) LED Backlight, AntiGlare Glass, Low-light sensitive HD Webcam (with Touch),Gunmetal Black

AMD Radeon HD 8670M Graphics 2GB

4GB PC3-12800 DDR3L SDRAM 1600MHz SODIMM

Intel Wireless-N 7260 2X2 BGN+BT

Radeon 8670M Graphics

First problem was trying to install linuxmint from a USB key. The display driver does not work out of the box. You will have to add radeon.modeset=0 to the kernel parameters in grub.

There is no grub menu shown during boot - if anyone can tell me how to show this then that would be appreciated.

So once you've installed linuxmint, reboot with the installer (from USB, with same kernel boot modification), mount the installed version and chroot. Something like this (assuming my installation is to /dev/sda1

sudo su -

mkdir 16

mount /dev/sda1 16

mount --bind /proc 16/proc

mount --bind /dev 16/dev

mount --bind /sys 16/sys

chroot 16

Now edit the grub file in /etc/defaults/grub and ammend the GRUB_CMDLINE_LINIUX_DEFAULT line to read

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.modeset=0"

Now reinstall the boot loader

update-grub2

Now you can boot the installed OS.

Wifi Intel Wireless-N 7260

The wifi driver is iwlwifi, but this keeps crashing on the stock kernel (3.11) - you have about 3 mins of wifi before it gives up.

Solution, install kernel 3.12:

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12.2-trusty/linux-headers-3.12.2-031202-generic_3.12.2-031202.201311291538_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12.2-trusty/linux-headers-3.12.2-031202_3.12.2-031202.201311291538_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12.2-trusty/linux-image-3.12.2-031202-generic_3.12.2-031202.201311291538_amd64.deb

sudo dpkg -i linux-headers-3.12.2-*.deb linux-image-3.12.2-*.deb


Otherwise all seems to be working, though I'm not a fan of the "click pad" but maybe I'll get used to it

Hope this is helpful!
