[Bug 1300914] Re: External screen undetected after first plug

 

I searched but I only found an error with different symptoms but the same log message:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1301398
As it claims that it was fixed in 3.15, I installed 3.16.0-37-generic from Utopic and voilà: It works without problems and error messages. So I am in a better position than Kamil in #28 but as I am even using the same model of notebook (different hardware configuration possible) we still do not know why it occurs.

Title:
  External screen undetected after first plug

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  On Ubuntu 14.04, the external screen plugged on VGA is detected and get activated correctly.
  However, if I unplug it and then replug it later, it is not detected anymore and the screen receives no signal.

  A way to get it back to work is to reboot or simply suspend the
  computer.

  Sorry but I have no idea of what package is handling that.
