Light Locker Settings Will Not Open

[Doug Nordquist]

Xubuntu 14.04: I had been trying to change settings in "Light Locker Settings." One of the settings I changed was to disable light locker (don't know if this matters). Now, when I open light locker settings from the setting manager, the window opens and immediately closes.

The file light-locker-settings.desktop in ~/.config/autostart might be bad. Try replacing it with the same file from /etc/xdg/autostart. You might have to change the file's ownership with chown. This fixed this problem for me. As for figuring out which settings are needed to get the screen saver to do what you want, I have no idea. Good luck!

Status changed to 'Confirmed' because the bug affects multiple users.

Otherwise, could you try to run light-locker-settings from a terminal and let us know what the output is? Thanks!

Same issue. After calling light-locker-settings on terminal i get this trace. Hope it helps, i was actually looking for a fix on why the screen blanks/goes off every 10min or so (against power settings)... :(

On a closer look, if i edit /usr/share/light-locker-settings/light-locker-settings/light-locker-settings.py and comment lines 235, 236 and 237 (related to loading user settings) it will load system wide settings correctly and then show the application form. since the user file was auto-created it seems there is an issue with it's creation.

Copying system's /etc/xdg/autostart/light-locker.desktop to ~/.config/autostart and calling light-locker-settings loads the form with success.

Further info provided in the comments. Seems to be related to structure or settings in the initial user-specific config py file.

Faced the same error. Reinstalled, but without success.

Seems that the psutil api changed some time ago.
After changing in /usr/share/light-locker-settings/light-locker-settings/light-locker-settings.py all calls to "psutil.get_pid_list()" to "psutil.pids()" light-locker-settings runs

@Florian

This works for me. Thanks.
