Hello! I have a little issue with Atril in the presentation mode (the full screen view obtained by pressing F5). When i have an Atril istance in this mode on a workspace, if I switch to another virtual desktop (ctrl+alt+left or right) some times, everything freezes and i have to restart X (ctrl+alt+DEL).
Hi @fenderico,
what graphics card do you have and have you installed any drivers?:
Have you run a full system update?:
Hi @wolfman, I have a nvidia geforce 820m with its own proprietary drivers installed, I’m on Ubuntu mate 16.10
Hi @fenderico,
I tried it out in presentation mode and it works fine, did you do the updates?, what drivers did you install for your Nvidia GPU?. 
I use NVIDIA binary driver version 340.101 (it says tested), should I use nouveau instead?
