Hello,
I am not sure whether this problem/bug has only occured to me, but when I put the computer to sleep by closing the lid and then opened it again all my input devices stopped working (embedded keypad and external mouse). I am looking forward to developers clearing this issue, though, note that it only happened once. I was needed to shut down the system from the hardware button. LUCKILY my work was saved… whew
Also, a little beside the subject is the matter with network status - when I hover the cursor over the network icon on the upper taskbar it doesn’t show anything, though the button works correctly. It didn’t happen in Mate 15.10.
I am using a Lenovo G50 with Mate 16.04
Thanks in advance!
