Periodically (every few reboots by the look of it) my external VGA output on my Laptop changes name between VGA1 and VGA2. For example right now xrandr is displaying:
timp@helez:~$ xrandr | grep VGA VGA2 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 433mm x 271mm
But next time I reboot my system that could easily swap to VGA1 instead.
I do have an Optimus graphics card, so that may be related, and I did in the past have Bumblebee installed, but I have since removed all the related packages and/or downgraded them back to their standard versions.
Has anyone seen anything like this or have any ideas how to fix it?
