[Bug] System freezes indefinitely upon suspend under high memory load

[Ronin-CK]

Description

When attempting to suspend the laptop, the system occasionally freezes completely, requiring a force restart. This occurs more frequently when the system is under memory pressure (60-80% RAM utilization).

Steps to Reproduce

1. Open multiple applications (60-80% RAM usage).
2. Trigger a system suspend (via menu, lid close, or systemctl suspend).
3. The system fail to enter sleep and becomes unresponsive.

Expected Behavior

The system should enter suspend mode reliably regardless of background application load or memory usage.

Environment

• Distro: Garuda Linux
• Compositor: Hyprland
• Noctalia-shell Version: 4.4.0
• Monitor resolution: 1920x1080 @ 60Hz

I fail to see why this would be a Noctalia issue?

[Ronin-CK]

@ItsLemmy I actually tested this under the same RAM load on KDE Plasma and it suspends perfectly, so the kernel/hardware seems to handle the pressure fine. The freeze only occurs in this setup.

It does not mean it's Noctalia, might very well be hyprland.

Maybe test without noctalia started on hyprland.

Noctalia is just a bar with a few panels, I doubt we can freeze and entire system.
