Comment 31 for bug 1181666

same here. 17.04 just got hit by this.
clean install ubuntu 17.04, nvidia gtx-1060 with proprietary driver.
I was hibernating my PC for about 3 weeks now, suddenly my mouse started to act weird. some clicks worked, some didn't I had problems with moving windows.

the keyboard was working fine apart from the windows key, bringing up activities, it seemed stuck, but occasionally became unstuck, very weird.

managed to logout/login and problem disappered.
