--- Comment #9 from Andrew Stubbs ams@codesourcery.com --- Alternatively, would switching a monitor from DVI to VGA or HDMI help?
I currently have two DVI monitors, listed as "DisplayPort-1" and "DisplayPort-2", and one laptop display, listed as "LVDS". No two monitors have the same native resolution.
xrandr --query suggests that "DisplayPort-0" and "VGA-0" are unused. I presume that maps to the HDMI and VGA ports?
