EdUBudgie
I've needed to return to my laptop to continue these comments, because it will make it easier to provide some of these examples with screen captures.
For the most part, using Vivaldi is not distinguishable from using it on my laptop, because I'd done a sync shortly after I'd installed it, and made settings changes to match those on the host. The one thing I wasn't able to do was to start a grocery order after I noticed some things we were out of after breakfast. Trying to log on to our online grocery store was impossible. I was presented with a captcha to prove that I'm not a bot, and I couldn't get past it. No matter how well I satisfied the challenges, it just kept repeating.
To be fair, this has happened with other distros in VMs, so it probably wasn't anything to do with EdUBudgie specifically, but with our grocery source. I almost didn't mention it, but it did cause me to leave my experiment early. I suspect the site noticed I wasn't logging on from my original location, although the browser was the same.
I'd done that once briefly earlier, too, but it's been long enough since then that I can't remember why that was necessary. If a Solus sync happens later today, I'll need to do that again, of course.
Playing my three solitaire games was exactly the same as on the host. Of course, the performance difference between the host and the VM was so slight that it wouldn't really show up in those applications. In others, like Thunderbird, it was more noticeable, but not really objectionable. Subjectively, though, the overall performance seems to be a bit worse than the other Budgie implementations I've tried in a VM.
That inspired me to compare this VM to others that I'd created, so I shut it down and viewed the virtual file manager from the host.
I was surprised to see how much of the 32GB of the virtual disk drive was already used. As I work with this VM much longer, I suspect that I may run out of disk space. That could be an issue for those (e.g., students) who may try to run this distro on a machine with small drives. Note that these other VMs have had the same packages installed (by me) and been configured at least as much as I have done for this one. The rest of the size can be attributed to all the rest that EdUBudgie had installed as defaults. I'll be exploring those a bit later.
That led me to check on how many unit file were enabled by this distro. I don't remember whether I did this earlier in the thread, but the answer is 78 unit files. That's not the most I've ever seen -- Ultramarine Budgie loads 156 -- but as I remember, EduBudgie's parent OS only loads 50-some. Solus, of course, loads 3 or 4, depending on the DE. And as I've pointed out before, Ultramarine Budgie takes a very long time to startup and shutdown. EduBudgie isn't nearly that bad, but it's certainly much slower than we're used to with Solus.
I'll close this post for now, and continue using the VM at full-screen for as long as there is more to see. Obviously, this is not Solus, but there may be some overwhelming advantages for students that could outweigh the negative issues I've listed so far. I want to keep this evaluation as fair as possible.
