Lock screen on suspend

Xfce#Lock the screen gives an introduction to screen locking, but I can't get it to work with xfce4-power-manager on resuming from suspend. I've found little on this [1] [2] and an old bug for Xfce 4.8. [3]. Locking via Ctrl+Alt+L works as expected (slock). Can others reproduce, and if yes, should I investigate further and file a bug upstream? Perhaps this could be related to the light-locker transition (where I use xinitrc). -- Alad (talk) 10:52, 13 July 2015 (UTC)

This functionality works fine for me but I use gnome-screensaver. This might be an issue for specific screen lockers as opposed to a general Xfce issue. I notice that there is an alternative "lock screen before sleep" option under Applications -> Settings -> Session and Startup -> Advanced. Perhaps that works where the xfpm option does not? -- Chazza (talk) 11:05, 13 July 2015 (UTC)
Indeed, it works with gnome-screensaver. It even uses gnome-screensaver when I symlink slock in /usr/local/bin to xflock4 (though the shortcut and menu do respect xflock4). Looking through the source, xfpm is supposed to use xflock4 though [4], so not sure what's happening here. -- Alad (talk) 06:04, 14 July 2015 (UTC)
It's worth taking a look at what xflock4 is actually doing here - it's just a shell script. As can be seen from the first for loop, it will try to execute xscreensaver-command -lock and gnome-screensaver-command --lock in that order and it will exit. Only if neither of those can be executed will it move on to deal with xclock and slock. So xfpm's behaviour is correct here.
Edit: Whoops, misread. Yes I see the problem here, the symlink isn't being respected. Not sure why that would be the case.
Edit2: The lock screen panel action button first tries to find the program in path before executing.[5] The power manager doesn't. That's probably the source of the inconsistency. -- Chazza (talk) 08:01, 14 July 2015 (UTC)
No activity since mid July - was a decision reached on this? -- Chazza (talk) 16:34, 17 September 2015 (UTC)
I couldn't get this working outside gnome-screensaver/x-screensaver, even when putting a symbolic link directly in /usr/bin, but I'm afraid I didn't get the chance to contact upstream yet. -- Alad (talk) 11:16, 19 September 2015 (UTC)
