I have a couple of services running in a GNU-screen session on top of Bash. Because one of the services contain sensitive data I have to constantly either close the terminal completely or lock the screen session using C^a X. Sometimes I forget to close or lock this window when leaving my desk which is not good so I want to know.

How can I get GNU-screen to automatically lock the window after XX minutes of non-use or get Bash/terminal emulator to execute the C^a X command after a time interval? I am aware I can lock the screen using the window manager, but I would like this in addition just in case.

Cheers.

See the idle option from screen:

idle [timeout [cmd args]]

Sets a command that is run after the specified number of seconds inac‐ tivity is reached. This command will normally be the "blanker" command to create a screen blanker, but it can be any screen command. If no command is specified, only the timeout is set. A timeout of zero (ot the special timeout off) disables the timer. If no arguments are given, the current settings are displayed.

Just to clearify: To get screen to lock itself after for example 4 minutes you would add a line in your ~/.screenrc file containing the following idle 300 lockscreen. –  Mogget May 22 '13 at 10:20
