i have two monitors. the monitors are of special type. they have buttons on the side to switch between video input and other inputs. the motherboard of my controller originally had a VGA input and an LVDS input. To be able to use the monitors we put an LVDS to VGA adaptor so that we have two VGA outputs now.
when i connect the two monitors to the controllers using Ubuntu, everythings initially works fine and the two monitors are displaying in a mirrored or extended mode. when i press the button to the side of one of the monitors to go to another input and come back, nothing is being displayed (and here is my problem)
when i install windows, everything works find even if switch away from the VGA and come back.
I am suspecting that there is a problem in the driver
i have spend quit a time trying to figure out the problem but with no luck. please help me
