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:

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.

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

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 attempting to address this. Keyboard hardware-disables in tablet mode, but touchpad is still active which needs to be addressed. No ACPI or keycode signals appear to be emitted for the various laptop,tent,tablet states.
