Package xtrlock

Minimal X display lock program

https://salsa.debian.org/debian/xtrlock

Xtrlock is a very minimal X display lock program. It doesn't
obscure the screen, it is completely idle while the display is locked
and you don't type at it, and it doesn't do funny things to the X
access control lists.

Version: 2.15

General Commands

xtrlock.1x Lock X display until password supplied, leaving windows visible
