Description Scott Robbins 2025-08-15 08:15:03 UTC
When doing a minimalistic install after choosing custom, then installing xorg-server, x11-drv-libinput and openbox as a window manager, if alacritty is installed, it won't start. Calling it from an open urxvt terminal gives the message
==============================================================================
thread 'main' panicked at /usr/share/cargo/registry/xkbcommon-dl-0.4.2/src/x11.rs:59:28:
Library libxkbcommon-x11.so could not be loaded.
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.
================================================================================
If one installs libxkbcommon-x11, alacritty then starts without a problem. So it seems as if libxkbcommon-x11 should be included as a dependency. I found this in both Fedora 42 and Fedora 43. I only tried with openbox, I suspect the problem wouldn't show with most desktop environments. I didn't test with other small window managers.

This is probably an edge case, as I think a great many Fedora users prefer a Desktop Environment, and there is the easy workaround of installing libxkbcommon-x11. (You don't even need libxkbcommon-x11-devel).

Reproducible: Always

Steps to Reproduce:
1.Do a minimalistic install of Fedora and install openbox as windowmanager. Install alacritty
2.Try to start alacritty. If you've installed a second terminal and start from said terminal,a message appears that libxkbcommon-x11.so could not be loaded.
Actual Results:
Results as described above. Calling alacritty from a urxvt terminal gives the message that libxkbcommon-x11.so can't be found.

Expected Results:
That an alacritty terminal should open.

Additional Information:
Opened alacritty once libxkbcommon-x11 is installed.

Thank you for the report.

It's sometimes hard to figure out which library dependencies are actually needed when the libraries are dynamically loaded at runtime instead of linked :(

I'll add a hard dependency on libxkbcommon-x11 to the package, that should resolve this problem.

Comment 2 Scott Robbins 2025-08-15 13:55:43 UTC
Wow, that was a quick response! Thank you. Once you've done it, I can very quickly throw together a new F42, 43, or rawhide VM to confirm it's good. 
Thanks again. :)

Comment 5 Scott Robbins 2025-08-15 17:32:26 UTC
Thank you! I've got to say, that was quick. I put together a fresh rawhide install with X and openbox, got the rpm from the bhodi link above, and ran dnf -y install on it. Started X and alacritty installed with no problems. So, I only have x86_64, so that was the one I tried, but as far as I can see, the problem is solved. Thank you for the super quick work.

Comment 9 Scott Robbins 2025-08-16 13:57:59 UTC
Adding this comment here as well as in the bhodi link. 

. I just installed a fresh F42 on a vm. Alacritty installed as did libxkbcommon-X11. However it wouldn't start, this time, because it was missing libXi.

Error: Os(OsError { line: 788, file: "/usr/share/cargo/registry/winit-0.30.12/src/platform_impl/linux/mod.rs", error: XNotSupported(LibraryOpenError(OpenError { kind: Library, detail: "opening library failed (libXi.so.6: cannot open shared object file: No such file or directory); opening library failed (libXi.so: cannot open shared object file: No such file or directory)" })) })

Installing libXi (again, didn't need the -devel) fixed the error and alacritty would open without a problem. I'm sorry, I didn't have this error when I reported the original bug, I guess something else I'd installed put in iibXi. This new f42 install just had enough to get openbox running with a few extras like xorg-xinit feh and dmenu.

As you said above, it's hard to figure out which library dependencies are linked when they're not loaded till runtime.
