I have a second monitor which works perfectly fine on Windows. However, on Ubuntu 13.10 I am running into a couple of weird issues:
If I connect it after booting Ubuntu, it duplicates the display of my laptop screen (at my laptop screen's resolution). The screen is however not detected in "Displays" and I cannot do anything with it.
If I connect it before booting, it goes straight to CLI and I cannot startx. It says "No screens found".
X -configure
also fails, saying that the number of created screens does not match the number of detected devices.
Any insight into this would be greatly appreciated.
