I am running into an issue with rotating a display. I am running a docked dell laptop and using two external displays. After boot when it goes to the login screen it displays only on my laptop display which I am not using unless I am out of the office. The secondary issue I am having is 22 inch display that is rotated vertically for viewing code, programming, etc. When I go into settings and set the screen to rotate and hit apply nothing happens. Any help with this would be appreciated.
Which graphics card is in the laptop?
Nvidia, intel or amd. The answer to what to do depends on that
you can use lspci | grep VGA to find the model of the card you are currently using.
You can screenshot a reply to me or write which one it is, depending on that I'll lik you to the right driver and how to install it
