Description

When Hyprlock is activated while monitors are disconnected, i.e. via Hypridle, Hyprland will show the "oops your locker crashed" screen, I will then have to switch VTT and then switch back for Hyprlock to be displayed.

Additionally, if Hyprlock is active while monitors are disconnected, and then reconnected, one of the monitors will be shown unlocked (desktop is visible, not interactive) while the lockscreen will properly be shown on the other.

How to reproduce

Unplug monitors or use KVM switch, and then activate Hyprlock. Alternatively Active Hyprlock and replug monitors for desktop visibility issue.

HI!

The first one is a Hyprland issue.
I can reproduce it with swaylock as well.
I think it is a regression, since I remember testing this before.

I can't reproduce the second one. That is an old problem as well.
Parts of it need to be fixed in hyprland and that is on the todo list.
However, hyprlock should immediately render the background color. Idk why it does not do that.
Your hypridle logs would be useful for this problem.
Also please post your hyprlock version.

Thank you for that info, I had assumed that it would be hyprlock to redraw on the monitor changes, but it is actually Hyprland that does that?

Do you happen to know if there is an open issue in Hyprland for that? I hadn't seen one. I've been using Hyprland since around October of last year and has always been an issue for me.

Wayland is a protocol that defines how clients and compositors handle that sort of stuff. To successfully draw on a monitor, both sides need to play ball.

I will check later and open one if none exists yet.

For this issue, it's actually 3 different issue from what I gathered.

1. The hyprland issue when starting a lockscreen while dpms is off.
2. Unplugging/Removing an output may result in dangling pointers #684
3. The background not immediately getting a new frame (could also be 2 perhaps?)

Fixed number 1: hyprwm/Hyprland#9399.
Number 2: #686
Number 3: #687

Tried the latest git version still hyprlock crash 😞

[Flat]

You'll also need to be running the latest git version of hyprland. It is working properly now for me.

[PaideiaDilemma]

@skarpinis Number 2 is still missing
