Lock Screen broken in Hyprland on ArchLinux-based distros due to an May 18 2026 update to the D-Bus library compiled into hypridle

See the bug report at:
hyprwm/hypridle#200

So don't panic. I trust a fix will be forthcoming from the ArchLinux team.

The community expects a fix by later today (19 May 2026)

Thank you. We tracking it on the discord server also.

In the meantime, I figured out how to recompile hypridle in CachyOS.
Likely not best practice, but I have it working again until the official binary update is published to the ArchLinux repo.

From my update in the CachyOS forum link

I’ve figured out how to re-compile hypridle on my own fixing the issue whilst waiting for the official fixed binary.
With a working system snapshot to restore my system config if it all went horribly wrong, I did the following:

sudo pacman -S hyprland-protocols

sudo pacman -S cmake

git clone https://github.com/hyprwm/hypridle.git\ncd hypridle

cmake -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr

cmake –build build –config Release -j$(nproc)

sudo cmake –install build

sudo reboot now

After the reboot, screen locking is again working in Hyprland. :+1:
This is the first time I’ve ever built from source to fix an issue. Very cool.
I’ll remove my manually built binary as soon as I see the official ArchLinux binary published to the Cachy repos.

Linux is my new favourite toy! :slightly_smiling_face:

Several people have offered more concise commands and approaches to recompiling hypridle at the original GitHub posting of the bug at hypridle segfaults on startup · Issue #200 · hyprwm/hypridle · GitHub than the commands I shared above.

And apparently, this is the proper way to do it:

Apologies if I'm oversharing, and thank you @dwilliam62 for keeping this project going. 🙏

No problem. For most ppl downgrade and wait for the update is preferred. many aren't comfortable with re-compiling

The fix has been released on Github in the last hour. The ArchLinux thread states that the buggy version has now been flagged as out-of-date, so the update should appear in ArchLinux updates soonish. 🥂
