I've installed Mint on my Dell laptop, but I installed while attached to a docking bay.
The laptop has a widescreen monitor, but the screen I'm using with the bay is not, so Mint detected that screen size during install.
Now when I run the laptop off the bay it runs in non widescreen mode leaving black bars down the sides.
As I do most of my work on the docking bay its not the end of the world but it would be nice to get it working. Is there a way to configure it so it can detect which screen res it should use?
