My computer is on Linux 16.04 (Unity), and when I do screenshot using Screenshot key (on my computer DELL Lattitude E5440 with French keyboard is Fn+Fin / Imprcran); I have to wait about 2 minutes (I've counted ~115s) for the screenshot to be taken.When I Use Shift+Screenshot (to take screenshot only in a specific zone of the screen), it's take about the same time to show the cross cursor (to select the area where to take the screenshot).After I can select the zone, after I select-it, the screenshot is immediately taken.So the problem is I think, something between the screen macro is called and when the screenshot program begin to works as well.I don't know how this works exactly between the moment we do the shortcut, to the moment when the program to take a screenshot is called; but I think here is the problem.Note that during this 2 minutes of lag, my computer and all programs working on it just running normally; just like I've never asked for a screenshot (but if I click many times to do the screenshot, it will take me many, one by one, after the unknown late I try to fix).I have no idea where to find the problem; so if you need more information about my computer (I don't know, like a certain software version or to do any command to get detailed information that may help us to find the problem), please tell me, and I will improve my question with these results ! For now, I don't know what can be useful for you.Processor of my computer: Intel Core i5-4310U CPU @ 2.00GHz  4Graphic card: Intel Haswell MobileOS: Ubuntu 16.04 LTS 64 bits$ xmodmap -pkekeycode   8
