Installation

Boot with nomodeset kernel option

Business as usual except for the fact it spams usb errors in every virtual terminal.

it might be helpful to silence the kernel printk in order to see yourself type:

echo 1 > /proc/sys/kernel/printk

Wireless

Supported in kernel, works out of the box.

Graphics

Supported out of the box. Xorg uses xf86-video-intel

Unless you boot the kernel with the no "nomodeset" option it will attempt to run the terminals at native res, which is hilariously tiny.

Xorg too will attempt to use native res which is fairly unusable.

Rather than run at lower res and give up the pretty, you can simply just use xrandr to scale to 50%

xrandr --output eDP1 --scale 0.5x0.5

Steam crashes trying to run games complaining about missing i965 module. It seems some applications treat it as accelerated, and some do not.

Needs Research

Touchscreen

Works out of the box.

Only supports simple cursor emulation. Gestures like drag down anywhere to scroll would be nice.

Needs Research

Touchpad

Works out of the box

I see a lot of complaints about this but it seems to be solid.

Gestures and the ability to middle click are still to be desired though.

Rotation/Conversion

You can easily rotate screen with xrandr, however it does not rotate touchscreen/touchpad input which makes it fairly awkward to use.

There is a project on github attempting to address this. Untested.

Keyboard hardware-disables in tablet mode, but touchpad is still active which needs to be addressed.

Also despite reports of special keycodes being emitted in the yoga 1, the yoga 2 does not appear to behave this way.

No ACPI or keycode signals appear to be emitted for the various laptop,tent,tablet states.

This may be a kernel issue. Needs more research.

Sound

Unable to get this to work.

Alsamixer sees 2 audio cards, one for hdmi which has no volume controls, and one with the built in controls with volume controls, but no regular audio output seems to work.

The system beep however, does work.

SD Card Reader

Webcam

Works out of the box

Accelerometer

Needs Research
