Whenever I lock the screen, the login prompt appears as expected. After a few seconds, the screen goes black (also as expected, after the login prompt times out), but then the screen turns back on again again a few seconds later. This cycle repeats indefinitely. Very annoying as it causes my screen to be on throughout the day/night when I can’t power off my laptop.
Happens on 4.2 with all IO devices plugged in or unplugged. Running on a ThinkPad X1 Extreme Gen 3.
I have similar issue on one laptop (also ThinkPad X1, but a different model), and there I know the trackpoint is broken - it’s more or less built-in mouse jiggler…
That was only part of the issue, the main was “presentation mode”! Thanks @barto!
(The single & is not a typo: In case the innerxfconf-query command to turn off presentation mode ever fails or hangs, xscreensaver-command -lock will still be engaged by xflock4.)
Great, this fixed the problem ! And sorry for the bit of delayed response, was away from home all day and wanted to check your solution before replying
