Confirming this problem exists with my Toshiba Satellite C650 (Core i3-2350M 2.3 GHz, onboard Intel HD Graphics 3000), with a fresh Xubuntu 18.10 Installation.
In my case switching to another Virtual Terminal and back to VT-7 (Alt- Ctrl-F7), returns me to an unblanked XFCE Desktop! For me another "workaround" is plugging an external monitor into the Satellite C650's VGA Port, which also unblanks my XFCE Desktop. Although terminating light-locker and running "dm-tool lock" does trigger the bug, under those conditions my VGA Port "workaround" does not work. I have not observed a "Locked Screen" and therefore blindly typing my password does not work... The problem does not exist with an Ubuntu 18.10 Installation on my Satellite C650. My own Bug Report https://bugs.launchpad.net/bugs/1803268 is a Duplicate of those one. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1801609 Title: Fails to deactivate dpms off mode after user initiated wake-up events(not system-suspended, just locked and dpms active) Status in xorg-server package in Ubuntu: Incomplete Bug description: Xubuntu 18.10 with Xubuntu.desktop session running. System will lock and turn-off monitors(automatically or manually), but--will not wake- up monitors upon keyboard or mouse activity. I can type unlock password, blindly and then the monitors will wake and show unlocked session. WORKAROUND: I uninstalled light-locker, then, I installed gnome- screensaver. Xfce4(Xubuntu.desktop) will fallback on gnome-screensaver if light-locker is not found or installed.
