I have Ubuntu 14.04 on a Dell XPS 13 laptop straight from Dell. They installed Ubuntu.

I have a problem whenever I have multiple windows of the same application open. Say I have 2 terminal windows or 2 sublimes. There will be 2 little tic marks to the left of the icon for the application on the launcher bar.

The first I click the icon the application surfaces. The second time I click it, the entire machine locks up and then reboots after a good 15 seconds of unresponsiveness.

I've tried googling this but I must not be using the right language. Any assistance with this would be awesome. Thank you.

I had the same issue and I solved it by :

  1. Open Unity Tweak Tool
  2. Press General
  3. Restore Default

I really don't know what causes the problem but that is what I did and somehow it worked well for me.
