This is a common "issue" with GDM on gnome. I have experienced it on multiple distros running gnome, where the keyboard and trackpad both freeze after I wake the laptop from a suspend. I wouldn't be able to do anything beside interact with the touch screen(lucky for me my laptop has a touch screen) to log in and reboot. It is very annoying and here is a very simple and quick fix for it that I have found on the internet. I hope this help :)
