Yep, same problem here. :(

I'm on Manjaro using 1.4 rc2, and I have the same problem. I installed Clementine from the repositories. ProjectM was installed automatically with it. I can see the presets in /usr/share/projectM/presets, but I can't figure out how to tell Clementine where they are.

So, I successfully compiled Clementine, and I found out that it stores visualizations in /usr/local/share/clementine/projectm-presets/. And those work. When you install Clementine from the repos, though, ProjectM stores its visualizations in /usr/share/projectM/presets. Since the set of visualizations I got from compiling was a lot smaller than all of the ones I got from installing ProjectM, I tried copying the other presets over to see if they'd show up in the visualizations menu. And they do!

So, if you copy the presets from the folders in /usr/share/projectM/presets to /usr/local/share/clementine/projectm-presets/, that should work. I didn't copy the folders themselves, because I wasn't sure that Clementine would search recursively. I just copied the contents (all of the *.milk files).

After we've finished the remaining work on the projectM 4.0 release, I'll see what I can do to improve the projectM visualization integration via a pull request.

Clementine currently uses an old copy of projectM's sources with a few custom patches to make it work due to some (already fixed) bugs in projectM, so these will no longer be required in the next release and Clementine can just use the shared library. I'll try to improve the settings page so users can easily add their own preset path(s) (and possibly also preset playlists).

The new release will also contain a ton of rendering fixes, making the visuals look more like Milkdrop's output (still not perfect though).

If you're interested in the development progress, you can follow our work here:

Still broken for debian, and repo version had visualizations disabled.

Yeah, I don't really expect something to happen anymore here, Clementine's been dead for a couple of years now. Strawberry is probably the way to go, but they've also remove visualization support entirely.

Development is still ongoing here from what I see. The last unstable release was 5 days ago... Debian and Fedora packaging those unstable releases. I think visualization fixes still can be appreciated by many users.

#7306 fixes it

#7306 fixes it

Cool! When that merge lands in a release I'll reinstall Clementine and check it out.
