Original report
What's wrong?
Hyprland reliably crashes (SIGSEGV) on resume from suspend when the laptop is woken by opening the lid. The compositor dies during the resume sequence, taking the whole session down and forcing a reboot.
This looks like an upstream Hyprland bug (a null/dangling surface deref in the touch-input path that fires during output re-modeset on resume), but I'm reporting it here since Omarchy 4.0.1 ships Hyprland 0.56.2 and it's fully reproducible on a stock install.
Steps to reproduce
1. Close the lid (system suspends).
2. Open the lid to wake.
3. During resume, eDP-1 is re-modeset and the touchpad resumes; Hyprland segfaults instead of restoring the session.
Root cause (from the crash backtrace)
The fatal frame is CWLSurfaceResource::client() called on a null/destroyed surface, reached via the touch-down path that runs while the output is being re-enabled:
#4 CWLSurfaceResource::client() <-- SIGSEGV here
#5 CSeatManager::sendTouchDown(CSharedPointer<CWLSurfaceResource>, ...)
#6 CInputManager::onTouchDown(ITouch::SDownEvent)
...
#14 Aquamarine::CSession::handleLibinputEvent
#15 Aquamarine::CSession::dispatchLibinputEvents
