Ubuntu Desktop - Random Rotate

Ubuntu installations go perfectly fine, most of the time at least. This morning I installed Ubuntu 18.04 in an HP Envy 15 having a 7th generation Core i7 processor. Things were off from the beginning. The installation screen was flipped 180 degrees (up side down). Knowing the installation well I went through it without an issue. Following installation the screen will rapidly change orientation. I did some digging and it turned out to be related to the iio-sensor-proxy which if I am correct is a daemon that will check sensors and do calibration. In my case it would freakout and rotate every time it wakes.

Fix

You can easy overcome this issue by removing the app.

#~ sudo apt remove iio-sensor-proxy

Warning

While this works, the daemon also deals with the gyroscope and ambient light sensor. I doubt the HP Envy 15 would have either. Even if it does, I can live without it.

The iio-sensor-proxy had a config file. In an earlier day I was able to just switch off the rotation. It was simply commenting out a line, which I don’t remember where.

Hope it helped and as always Happy Hacking!
