The file has been written correctly.

jim.madge:~$ cat /etc/xdg/autostart/light-locker.desktop 
Hidden=true 

[JimMadge]

I tested the lock screen and it seems to be working,

• I closed my Guacamole tab
• Opened a new tab and connected to the workspace
• I was prompted for a username and password by the xrdp login
• Went straight back to my desktop session, no need to unlock

LGTM

[JimMadge]

Actually, this might not be right. The screen still locks after idling for some time.

[JimMadge]

Possibly because the file is missing the [Desktop Entry] group header

[jemrobinson]

Or it could be that we're using a different lock screen programme - note that the previous instructions were for XFCE3. I think there's now an xfce4-screenlocker.

[JimMadge]

Hmm, that might be right, light-locker isn't installed 😄.

[JimMadge]

Probably xfce-screensaver, you can trigger the lockscreen with xfce-screensave-command --lock.

[jemrobinson]

Happy for you to either uninstall it (although I guess this might break a meta-package) or to disable it similarly to light-locker.

Trying that package in #2128
