It may take me a while to try the BIOS update. I am having difficulties doing it since I don't have Windows at all on my machine (and the update is Windows only...).

Sometime between April and now, there must have been a kernel upgrade that messed it up. I saw a few other bug reports that eventually suggests I go to kernel 3.16.0. When I was on 3.13.0-63, my VGA output would work with the boot up screen and the log in screen. But once I log on the VGA port seems to be inactive and I can't get the output back. HDMI still seems to work, though the projectors I have access to don't have HDMI inputs. After I upgraded to 3.16.0, the VGA output would still work during the boot up and log in. Again, once I log on the VGA stopped working. However, when I switched to a text terminal (e.g. Ctrl-Alt-F1) I can see the VGA output again. As soon as I switch back to GUI the VGA output stopped working. The "Display" setting in System Settings cannot find an external monitor, nor could xrandr. My current work around is to use the HDMI port with an HDMI -> VGA converter. That seems to do the trick for now. Both Display setting and xrandr can see the HDMI connection.
