I think you solved that by yourself: you're using Python 3.9.1 when Solus is officially shipping 3.7.9.

How is pulling in polkit-gnome, scrot and dmenu as required dependencies "simple defaults"? I don't even use dmenu with i3 (I use rofi) and you can very well use the KDE or MATE polkit daemon instead of the GNOME one...

I would argue that music player control, which is included in the default configuration, is more complex and inessential than wallpaper configuration.

This is pretty silly. Of course it doesn't have a wallpaper. Aside from some pretty simple defaults, the whole point is you configure the rest of it.

A question is, which wallpaper should be used? Should there be a special wallpaper for i3 like there is for KDE?

Keyboard disabling started working after latest general system upgrade. Auto rotation started working after installing iio-sensor-proxy.

This appears to be fixed now. I cannot reproduce.

Umm, yes, you're right. Do you know if gst-inspect-1.0 | grep lv2 should give me lv2 plug-ins I have installed? Because it shows nothing.

Isn't the pulseeffects issue rather related to the lisp-plug-ins integration?

Since the 4.5 update Pulseeffects gets its equalizer from calf, so it's grayed out. Right now, only feature available is autogain, so I consider Pulseeffects broken at this point. Should this thread be continued or new one made?

Solid work @so-lo =)

I packaged before but not on Solus so I think I still fall into the required noob category. :)

Confirmed, we do not have pkgconfig(lilv-0) (lilv / lilv-devel, the library responsible for lv2 plugin support) in gstreamer-1.0-plugins-bad package, hence why it is not enabled. Considering this an improvement over a package fix since the gstreamer bad plugins package isn't fundamentally broken.

Approved. If someone (read the IMPORTANT bit after) wants to patch the gimprc file and provide a package update patch for it while I'm "away" on holidays, go for it. Otherwise I can when I'm "back". Here's the steps:

No. Those that want it will already know how to add it into the file or understand that this is something obscure enough and they'd already Google it and as a result find the answer.

@JoshStrobl Can we at least put it in but commented out, so it's easy to enable?

No.

Basically no distribution I have ever used does this. The only gain I could possibly imagine is making sure you didn't type a wrong number of keys while entering your password, then again you could understand you did this with the re-type prompt given 2 seconds later.

Please no! Not displaying asterisks is the standard Unix way of doing it, if a user wants password feedback he can turn it on himself from that file.
Having this enabled is also a security issue, because anyone looking over your shoulder can see how many characters you have typed.
