I see the same with: kubuntu 17.10 Nvidia graphics (G84GL [Quadro FX 570]) Nouveau driver
When power management kicks in to switch off the screen via dpms, then it is impossible to resume operation. As you move the mouse, there is no screenlock screen to enter the password, just a black screen with the mouse cursor. All the relevant KDE/plasma processes are active, and so is the screenlocker process. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/785681 Title: Unable to unblank screen, cursor still present Status in xserver-xorg-video-intel package in Ubuntu: Incomplete Status in Baltix: New Bug description: Binary package hint: xserver-xorg-video-intel This is ~ev filing this bug on behalf of Ellen. When her laptop blanked the screen, she tried to unlock it; however, it did not return from this state and only the mouse cursor was ever visible. Switching to a VT showed that all the desktop processes were still running. Killing gnome-screensaver did not fix the issue, nor did running unity --reset. This issue occurs sporadically.
