I am new in Linux environment, but i know some stuff.
I've just installed Ubuntu 19.04 Desktop on my Lenovo MIIX 300 and it got issues with screen rotation.
I've removed iio-sensor-proxy and to rotate my screen i'm using xrandr
command in terminal.
Very soon I've found that my Touchscreen is not working properly so tried to change some values in xinput
but nothing happened no matter what values i tried to set.
Here is my xinput list and I used this line:
xinput set-prop X "Coordinate Transformation Matrix" <values>
For X equal to 2, 4 or 13
Nothing happened, nothing have changed. I'm curious to see which prop values i need to change. This list above was made with keyboard dock unplugged, so you can see only the inputs included in the tablet part.
I recently found out, that even with the iio-sensor-proxy touch screen does not work properly. It works only in one position, as always (in 'normal')
I've also problem with charging, sometimes Ubuntu shows the charging icon, sometimes not, but there's always sound when i plug and unplug the charging cable. It's not that important as problem above, because it charges properly when system is off.
