Lenovo Yoga 2 Pro

These are notes for getting Linux Mint running well on a Lenovo Yoga 2 Pro.

Wireless

The ideapad_laptop kernel module blocks the Intel 7260 wireless card. I know the Fedora folks fixed this with a patch, but that's not made it into the kernel Linux Mint is using. So, in the meantime, you can blacklist that module by adding the following line to /etc/modprobe.d/blacklist.conf:

blacklist ideapad_laptop

Display

The Lenovo Yoga 2 Pro has a display with a ridiculous resolution of 3200x1800. It looks great on Linux with applications that support it well, but many applications just aren't ready for HighDPI displays yet (Chromium, Dropbox, Virtualbox). The internal display doesn't make a 1600x900 mode available via its EDID, so you can't easily choose a lower DPI resolution to use. Kernel Mode Setting (KMS) (which Linux Mint uses) makes this even harder.

So, what I've got here are an EDID binary file and instructions on how to run a Yoga 2 Pro (or, possibly, similar display) at 1600x900.

Display Setup

These instructions work on Linux Mint. Your distribution may vary.

1. Create the /lib/firmware/edid directory if it doesn't already exist. It didn't on my Linux Mint installation.
2. Copy the 1600x900.bin file into that directory.
3. You'll need to get these two lines into your kernel options. On Linux Mint, you can edit /etc/default/grub and make sure you have updated GRUB_CMDLINE_LINUX to look like this:

GRUB_CMDLINE_LINUX="drm_kms_helper.edid_firmware=edid/1600x900.bin video=eDP-1:1600x900-24@60"

Recompiling the EDID File

If you feel the need to change the 1600x900.S file, you can do that by placing it into the Documentation/EDID directory of your Linux kernel source and running make.

Powertop

Install the powertop package and add powertop --auto-tune to /etc/rc.local. I find powertop to do a nice job of enabling a lot of power saving features.
