Do have the uinput rule inside your udev rules? Or if you can live without the button mapping feature: Try to start Projecteur with the I havn't had time and motivation to really investigate, but there seems to be all kind of issues with newer Ubuntu versions + wayland. |

On another note: on newer Ubuntu versions (starting from 21.10 as far as I know) there are also issues related to uinput and (probably) wayland. No issues while opening or creating the uinput device, but the events sent to it seem to be blocked or not forwarded to Gnome. |

I've begun trying to play with projecteur on RHEL9 by installing the Fedora 34 RPM, and I've found a few issues.
It appears that there is a dependency on qt5-qtwayland, which is not in the RPM spec file:
Once resolved, it appears that the application fails to write a configuration file and core dumps:
