Use a pixelated version of your desktop as your lockscreen with i3lock – Hund – Linux, plaintext & minimalism

I decided it was time to spice up my lockscreen, I’ve been using the same old static picture for what feels like years now.

@mike I use this myself and am very happy with it.

@andrewebdev @mike

That is really cool. Thanks for building this, @hund!

On my home computer, I'm not concerned with someone looking at my screen when it's locked. So I use something similar but without the pixelation: #xtrlock (https://launchpad.net/ubuntu/trusty/+package/xtrlock).

(If I were more concerned with visual security, I'd probably go with #slock, but then I like that sort of thing).

xtrlock : Trusty (14.04) : Ubuntu

xtrlock is a very minimal X display lock program, which uses nothing except the Xlib library. 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.
