I can move my mouse around, see wall paper and top panel or switch to ctrl-alt-F1. But I cannot click anything nor do any key combination work.
What should I do beside restart lightdm? I chose to suspend because I don't want to lose my data. If I have to restart lightdm every time resume from suspend, I'd rather shutdown my computer.
how can i get normal suspend functionality back?
im using lenovo e420 laptop intel hd 4000 graphic card and native driver (or no driver? at least I never install anything manually)
PS: I just tried unity --reset and it took forever to complete so I decided to stop it. However, when I switch back, I found the chrome comes out but still cannot click on panel or wall paper. But key bindings work fine inside chrome
