Multiple screen setup no longer working since version 1.2.0. (X11)

[dataCobra]

Describe The Bug
When the screens get locked only the primary windows gets a screenshot, the other screen only has a white image. The visual typing indicator gets displayed on both screens. (Both with and without blur)

To Reproduce
Steps to reproduce the behavior:

1. Have a multi monitor setup
2. Use a version >= 1.2.0
3. Lock the screen automatically or manual
4. Screenshot for primary but white background for other screens.

Expected Behavior
All screens/displays should show a screenshot from the contents when the lock is in place.

System Info:

• Void Linux
• i3lock --version = 2.15
• i3lockr --version = 1.2.0 and 1.2.1

Might be because scrap is used for screen captures since 1.2.0. I'm on holiday right now so I can't work on this for the moment.

Can you try using scrap (one of the examples should work) and see if it captures all your monitors?

Looks like scrap's Display::primary (as used here) is the culprit. You'd want to iterate over all available displays with Display::all() like they do in their list example

[dataCobra]

I tried to create a patch with Display::all() but my current Rust knowledge is not enough to figure out how to make the code work with a Vec<Display> instead of the Display.

Couldn't figure out how to use the available functions to iterate over every display in the vector.

I've opened a PR here. This works for me on a setup of 3 monitors, which I tested with

• all the same resolution and no offsets
• differing resolutions and differing top/left offsets

I doubt it's foolproof, but it should at least be a start.

Until the PR is merged, you should be able to install and use the forked version available at that pull request. If you run into bugs LMK
