I’m saving this post. I’ve managed it in the past but even then I never knew how.

I don’t think so. I think they sort of have to branch off as lemmy gains users.

No. Lubuntu is designed to use very little resources which makes it faster on slow hardware where the os is a lot of the load. If you have fast hardware, regular Ubuntu might use (making this up but the point generally stands) 2%CPU and 3G of RAM and lubuntu would use 1%CPU and 2G of RAM. That would be a much larger boost if you have a much weaker CPU and only 4G of RAM, but you likely wouldn’t notice a difference on fast hardware.

Edit: spelling

I might do that just to force myself to organize and move files out of downloads.

My understanding is that both are more or less just arch, except that Manjaro holds back update on some packages and breaks stuff.

I take the approach of settling into a distro then getting bored and messing with stuff I shouldn’t (at least on a daily driver) and reinstalling out of necessity, sometimes changing distros as well.
