Readlines () # handles the newline symbol for i in range (len (getScreens)): getScreens [I] = getScreens [I] .repla ce ("\ n ") ") # compare the higher resolution display if int (getScreens [1]) < int (getScreens [3]): bigger = getScreens [2] little = getScreens [0] else: bigger = getScreens [0] little = getScreens [2] # use the larger monitor as the current output. Os.popen (" xrandr-output% s-auto-output% s-off "% (bigger, little))
