Please post only one problem per bug. Btw. I guess that your report is more a question also mentioned under Question #26807.
If activating of your external monitor with xrandr after hotplugging without the option --left-off doesn't work (xrandr --output VGA --auto) please create another bug report. If the monitor powers on but only have the wrong resolution it should be already covered through this bug Bug #158415.
