The bug i reported manifest and you cannot deselect the mirror state. work around: 1) dont' touch anything in the setting 2) disconnect the cable and monitors 3) reboot with the monitor disconnected 4) log in and only when plasma is loaded connect the monitors 5) the old configuration is back with the 3 monitor set up as it was at beginning -- You are receiving this mail because: You are watching all bug changes.
