XScreenSaver doesn't lock screen on suspend

[Giulio De Pasquale]

XScreenSaver does not lock screen on suspend even with gnome-screensaver removed. With the standard "CTRL-ALT-L" shortcut the screen is NOT locked with xscreensaver; this is solved by setting that shortcut to 'xscreensaver-command -lock'.
Even with these "workarounds" the screen is locked using Ubuntu's standard lock screen and not with xscreensaver's one.

Does running "sleep 2; xscreensaver-command -lock" give you the xscreensaver lock screen?

[Giulio De Pasquale (depasquale-giulio)]

I added "sleep 2; xscreensaver-command -lock" in the shortcut but that doesn't change anything. Even without sleeping the shortcut worked. When I close the lid of my laptop (a Lenovo x230) I get the default Unity lock screen and when the time set in xscreensaver settings expires, I even have to unlock my desktop twice. I just want the xscreensaver one.

I wanted you to run "sleep 2; xscreensaver-command -lock" on the command line in a terminal window. The sleep is there only to not trigger anything when you release the Enter key.

If you are using Unity you cannot expect xscreensaver to work. Unity has explicitly been made to only use its own screen lock functionality and to not be compatible with other general screensaver daemons. You must ask the Unity developers or switch to another desktop environment. I can recommend LDXE (Lubuntu).
