As the title suggests, I guess this is a kernel issue because before the 4.0 update I had never had this kind of issues. After waking up from sleep, neither the keyboard nor the touchpad work (Ironically, usb wireless ones do work). I must hard shut it down.
Also, the screen seems brighter at the same level than before (2 bars of brightness). I doubt these things are changed with each update. Or are they? In any case, how would I go about editing this? I'm no linux guru but I know enough to terminal my way into / and sudo gedit files, lol.
I checked, and this hasn't been reported
