I have Ubuntu 12.04 installed with a VGA splitter creating dual monitors. However when using Ubuntu 12.04 with the VGA splitter the two monitors are mirrored and when going to the "Displays" Settings the is only one monitor which is detected and when "Detect Displays" nothings happens.
This is what "Details" name my computer. Different to what Windows say...
