I don’t know if anyone else noticed this, but I certainly have. It’s not that it can’t be worked around. It’s that Gentoo-built desktop managers lack the polish other pre-mangled distributions like Ubuntu provide. I miss that.
Presently, I’m using KDE, and as it turns out, it has the most integration issues, in my experience. The only thing in GNOME that felt thrown together was super-user authentication and printing, whereas KDE has issues with NetworkManager, PulseAudio, super-user authentication, and external storage mounting, and I’m sure I’ve only scratched the surface.
The plan is to spend the rest of my summer reporting on these issues so they can be resolved. With fingers crossed, bug reports will be filed and fixed.
