System Installation – Fix Ubuntu 19.04 Screen Orientation Issue

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.
