Description

Bug Report: Suspension via keyboard shortcut "s" instantly wakes the system

Description

When using the keyboard shortcut to suspend the device (holding down the s key), the system enters suspend mode correctly, but wakes up immediately without any additional user action. ⚠️

Actual behavior 🚨

• The shutdown, reboot, logout, and suspend buttons work fine with the mouse: a long-click on the icon shows an interactive loading bar and triggers the action properly.
• The keyboard shortcuts for shutdown, reboot, and logout also work as expected.
• Only the suspend shortcut (s) fails: the device enters suspend mode, but because Arch Linux suspends very quickly, the s key remains physically pressed. The system interprets this continuous keypress as a wake-up command and immediately wakes itself.

Probable cause

The key-down event is not released before the kernel completes the suspend process. Since the s key stays pressed, the system registers it as a wake request just after entering suspend mode. This does not happen with the mouse because most GNU/Linux distributions ignore mouse clicks as suspend-canceling input.

Affected system

Tested on Arch Linux, but likely occurs on any distribution with very fast suspend times.

Proposed solution 💡

• Trigger the shortcut action on key release instead of key hold.
• Alternatively, ignore any keyboard events that arrive during the suspend/shutdown process.

Expected Behavior

Expected behavior ✅

The computer should remain in suspend mode until the user manually wakes it (for example, by pressing the power button or a dedicated wake-up key).

Steps to Reproduce

Steps to reproduce

1. Open DankMaterialShell.
2. Use the suspend shortcut: press and hold the s key. ⌨️
3. Notice that the screen turns off briefly (entering suspend), then turns back on by itself with no additional interaction.
