I use KTimeTracker to track on which desktop I'm working. However, when I lock the screen, KTimeTracker does not record such event. It simply keeps counting time spent on the last active desktop (which makes sense as it is still active under the screen lock). Proposal: Add one additional option to desktop tracking feature which would activate when the screen is locked. I'm using KTimeTracker 4.14.10 from Debian unstable.
Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I will be closing this bug.
