I have caffeine 2.9.8 and lubuntu 20.04.3. I want to prevent screen auto-lock while i'm reading a pdf.
In my typical usage i'm using Document Viewer (evince) in a normal window (not full screen) with caffeine activated through the indicator in system tray. But if i leave the system long enough without key press/ trackpad use, the screen keeps getting locked.
Am i using caffeine as intended? If not, is there something i can do to not have my screen getting locked?
I don't want to disable the screen lock completely.
