           Summary: Hot plugged VGA output doesn't work
           Product: xorg
           Version: 7.7 (2012.06)
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium

I have Toshiba Portege R600-10Q laptop (a model from 2009) which has an Intel
GS45 graphics chipset. It ran Windows Vista when bought, and the VGA output
worked as expected. 

I recently installed Ubuntu 14.04 64-bit on the laptop. When I have a VGA cable
plugged in at boot up, the VGA output works fine. If instead I plug a VGA cable
in after boot up, the external monitor is recognized, but receives no
signal.This happens with several different monitors.
