If you are going "around and around" with Ubuntu 18.4.x for anything from the logon loop to not being able to get the Nvidia drivers to install via "Launchpad" then you might want to try Zorin (core).

Now that I've refreshed my ux head a bit, I can't say I've found much grief with 18.04.
There are a few things I do, however, that make life easier.
1) Load Samba, so I can use my Win10 box across the network for basic file edits and admin, especially LAMP admin.
2) Enable local SSH and load PuTTY on the Win box, for places where Win across the network can't handle the job (e.g. ownership, permissions, symlinks, etc.)
3) Forget Gnome/Nautilus exist. Not needed with 1,2 above in place.
4) Do use dos2unix across SSH where needed after edits.
5) Do updates and installs across SSH from a terminal window. Easier than GUI anyway.
These days, about the only time I go downstairs is when I actually need to touch the box itself.

About how much system RAM is required per CPU job for Rosetta?

Yes they don't have GPU apps unfortunately.
Please note nothing against Rosetta, i like the project and participate sometimes and wish to do that now.
But is a "relatively small" project who grows exponential in the last days, exactly maybe the Covid-19 crisis.

Some projects will let you pick the specific applications you want to run. So far I haven't been able to see where we can select the Corona-19 only.

Other Note: Rosetti@Home uses significantly more memory than Seti@Home. So you may get a "waiting for memory" message.

And I had to reduce available memory in BOINC to 75% when a user is active or the screen response became very, very sluggish.

They did a month ago and provided results. But I don't think they are currently running any Corona virus campaigns.

Sad to see the hibernation, but there is an urgent need now to "solve" the Chinese Disease COVID-19 problem.

I'm switching to Rosetta@Home to process protein folding/modeling.

SETI lost my previous data and accounts; I had joined early 1999 and ran the SETI project on all available workstation hardware and the servers at a 5000+ employee organization. Wish I had those numbers!

Best to all!

for i in `boinccmd --get_file_transfers | sed -n -e 's/^.*name: //p'`;do boinccmd --file_transfer http://setiathome.berkeley.edu $i retry;done

This command will give the boot to stuck transfers if you don’t want to run additional software.
