Configure the tmux Lock Command

Description

To enable console screen locking in tmux terminal multiplexer, the vlock command must be configured to be used as a locking mechanism. Add the following line to /etc/tmux.conf:

set -g lock-command vlock

. The console can now be locked with the following key combination:

ctrl+b :lock-session

Rationale

The tmux package allows for a session lock to be implemented and configured. However, the session lock is implemented by an external command. The tmux default configuration does not contain an effective session lock.
