When i connect OpenOffice ppt for projector, it doesnt display or detect anything.While i can run the same in my windows OS installed alongside. I donot know if it is a possible driver problem or a software problem. Please help incase someone has solved such a problem.
When an external monitor / projector is plugged in, Ubuntu does not automatically switch it on. Normally, you can do this by pressing a key combination which depends on the keyboard you are using. Often its
Fn+F8 or something similar, often containing two displays.
You can also click on
[System Menu] -> Display...:
which brings up a dialog like this:
There you can fine tune the configuration you like. (relative position of the monitors etc.)
Note: LibreOffice has nothing to do with this.
