Problem description ------------------- Once my laptop "locks" due to inactivity, after entering my password my main laptop screen is blank. Only the second monitor, which is connected to the laptop's mini hdmi port via a vga-to-hdmi dongle, is visible. I can enable my laptop screen from the second monitor via System Settings==>Displays, however once the screen locks again due to inactivity, the problem returns. Also, if shutting down while the laptop screen is blank and disconnecting the second monitor and then rebooting, the laptop screen remains blank.
Hardware -------- I have a Intel(R) Core(TM) i7-3517U CPU @ 1.90GHz, which I believe uses Intel HD Graphics 4000 Software -------- Stock standard Ubuntu 13.04 Feedback -------------- After pointing to the xorg-edgers ppa and accepting all changes suggested by the upgrade (apt-get upgrade), which includes version 2:2.99.906+git20131213.f350a136-0ubuntu0sarvatt~raring of xserver-xorg-video-intel, the problem described above persists.
