Hey! First, sorry about my english, i'm from Argentina. Here is the thing: I installed Elementary OS Loki 0.4 on my Lenovo G470. It works great. But I have one problem: when the pc get suspended, and unlock it, it works great. But, if i block it, when I try to login, it moves the cursor, but nothing else, cant write the password. The same happens when closing the dim (not always). In those cases, I go to the terminal and try to restart lightdm, with no success, the cursor moves, i cant write the pass, and the wallpaper gets whole black. Any idea about this? Thank you for reading!
