Since a couple of weeks ago I've been experiencing strange issue with light-locker.
When a screensaver (a blank screen) is activated my machine is locked, that's fine.
However, when I try to unlock the machine and log in back to the system, it's impossible. When the blank screen disappears and light-locker's window is back, the screen is flashing, it's impossible to enter any character to the password input field, the menu with users available is either not responding or if it's open, but it's blinking, not responding neither to the keyboard nor to the mouse.
The only solution is to go to the text console (Ctrl+Alt+F1) and kill the light-locker process.
I've tried to investigate a little bit and my findings are as follows:
This thing happened when I was on the 4.15.0-70 kernel.
Then I tried to boot to the previous kernel 4.15.0-66 - everything seemed to be OK.
On previous Friday I upgraded to the 4.15.0-72 kernel and today I'm experiencing the same issue again.
It's a notebook Dell Latitude E7470, no a dock station, the second monitor (marked as the Primary) connected via HDMI, notebook's display is disabled.
BASIC INFO:
Xubuntu
Description: Ubuntu 18.04.3 LTS
Release: 18.04
light-locker:
Installed: 1.8.0-1ubuntu1
Candidate: 1.8.0-1ubuntu1
NB This issue is hard do describe for me as I'm not a native speaker, the one reasonable thing might be to record a short video... |
