Lock your KDE4 remotely (via regular KDE lock)

DISPLAY=:0 /usr/lib/kde4/libexec/krunner_lock --forcelock >/dev/null 2>&1 &
Forgot to lock your computer? Want to lock it via SSH or mobile phone or use it for scheduled lock? TIP: Make a alias for this (e. g. as "lock"). I found some howtos for ugly X11 lock, but this will use regular KDE locking utility. Note that KDE 3 is using utility with another name (I guess with the same argument --forcelock) Tested on Kubuntu 8.10. Stay tuned for remote unlock.

  • With this you can unlock your KDE4 session via SSH, via mobile phone SSH or e. g. scheduled task in crontab (without asking password). Useful when you need to grant somebody access to your locked profile remotely. Create an alias (e. g. as "unlock") and use with remote KDE4 lock. This works only on KDE4 boxes because KDE 3 is using utility with another name. Tested on Kubuntu 8.10.

  • If you wish to launch the kde4 screen saver without the password prompt to exit, use this command: qdbus org.freedesktop.ScreenSaver /ScreenSaver org.freedesktop.ScreenSaver.SetActive True Also can be done with: /usr/lib/kde4/libexec/kscreenlocker --forcelock

  • Usefull as a light blink to remember events, mails, intrusions, etc... yet another output Since nobody ever uses the scroll lock function... Usefull to interface a linux system with some hardware, for example, opto interfacing the keyboard led to a relay to remotely reset, etc. ( a simple LDR glued over the LED will do the trick ) xset led 3 turns on the third led, ie, Scroll lock xset -led 3 turns it off xset led 1 turns on Numerical Lock led ( doesn t work on all computer ) xset led 2 turns on Caps Lock led ( idem ) Using it as a reset watchdog, the relay expected light pulses. Shall the computer hangs, the relay releases and reset the machine ( discharge of a capacitor ) ;-)
