Deranged Screen

Alright, this is a fairly weird problem, so bear with me. I am on my laptop, and evetything on my laptop is working fiine, however the image inside my screen, be that the desktop or SA is flipped over. This is making it almost impossible to type anything more complicated than this.

Seriously the scenario is really annoying me. Help me. Please.

Right click desktop -> properties -> settings -> advanced.

After that, there should be a tab for your graphics card. You should be able to fix it somewhere in there (I'd be more specific, but it varies depending on your card).

I did try that ... but it didn't work. However subsequently I have managed to fix it by pressing the 'Alt Gr' button and the down button.

I have no idea how I managed to get in the perpendicular state however.
