I recently installed the latest ubuntu 18 and randomly the screen just rotates, i usually have to CTRL+ALT+T to bring up the terminal and do
xrandr -o normal to get back the screen display correctly. I have gone through the internet in search of the cause and also I know there is a similar question on Screen randomly rotates on Ubuntu 17.10, but all those solutions worked for devices that have orientation capabilities, am on a HP Laptop which DOES NOT support orientation laptop, what could be the reason and how do I fix this. Any help please would be really appreciated.
Laptop model is HP ProBook 4540s
