I have hp probook 4431s with an AMD card and when I boot into 19.04 live cd the screen was inverted (never happened on the previous 18.10). I installed it upside down but when I booted into the OS the screen was in normal state but the functionality is still upside down and the cursor was upside down and I don't know the solution. I also tried xrandr but didn't get it right. I have not so much of deep knowledge and really don't want to switch back to Windows.

  • 19.04 seems to have an issue with interpreting the orientation sensor backwards; my HP Pavilion dv7 has the upside down screen as well after upgrading. I was able to get the desktop back into the correct orientation with xrandr -o normal and then turning on orientation lock. Unfortunately, this only applies to my desktop when logged in, and the lock screen is still upside down when I'm not logged in. I think you would have to entirely disable whatever triggers the auto rotation. – Herohtar Apr 19 '19 at 20:20

sudo apt-get remove iio-sensor-proxy

Remove the above sensor

  • Thanks I worked. – Nabeel Yousaf Apr 20 '19 at 7:22

    This does prevent the screen from flipping upside down, but essentially removes all functionality of those sensors. Is there a way to configure it properly? – Herohtar Apr 23 '19 at 3:00
