Arch Linux User Repository

There is a new package subtitleedit-avalonia that provides a preview build of SubtitleEdit that is based on the cross-platform Avalonia UI toolkit and provides a vastly improved experience on Linux.

It's still experimental and some of the app's features may or may not work properly, if at all, but I thought I should share it here because it already works generally fine and more Linux users could mean more Linux bugs squashed more quickly.

how do i fix broken appearence fonts and drop down sections

@tyrannis.hawk sorry for not responding earlier, I was aware of your request and you're absolutely correct, ffmpeg is indeed required for extracting waveforms, so I've added it as a new optional dependency. Thanks for reporting this.

ffmpeg is an optional dependency, required to produce a waveform of a video file. It would be great to add that to the dependencies.

@Nocifer, thank you so much for taking the time to explain all this. Meanwhile I think is back to VirtualBox :)

That would be up to the Mono framework I believe. If there exists some kind of switch that can be used to toggle Wayland support for Mono like e.g. an environment variable like MOZC_ENABLE_WAYLAND that Firefox utilizes (I doubt it) then you could use that; otherwise, if I were you I wouldn't hold my breath, as I can't see the Mono project implementing such a huge change if they haven't bothered to do it already. But of course I could be wrong.

The only other solution would be for SubtitleEdit to abandon Mono/.Net and refocus on the cross-platform dotnet, but I don't even know if that would be feasible, let alone if the developer would be willing.

So for good or bad, I guess XWayland is here to stay for the foreseeable future :)

@Nocifer, I am on "pure" Wayland, so there is no chance to have this without XWayland? I am sorry, I should have mentioned this from the first comment :(

@emvidi The gist of the error is that it can't find an X server, which means that it's actually trying to run through XWayland. Could it be that you're on a "pure" Wayland system that doesn't have XWayland installed? That's the only thing I can think of off the top of my head; that, or XWayland is there but it's not set up properly for some reason (i.e. as mentioned the DISPLAY environment variable is not being set).

Do other X11-only apps on your system run properly on Wayland?

@Nocifer, thank you for your answer, this is what I get when I launch subtitleedit:
