My recovery of NOOBS on a 32 GB SD card is largely successful. I particularly like it coming up automatically filling an "1824x984x24" TwinVNC window. Raspberry Pi Configuration's "Set Resolution..." doesn't even offer such a resolution. It leaves my column of disk icons on the left of Workbench free and the dockies at the bottom partially uncovered.

But some things aren't as they used to be, and I wonder if it's because I have done something wrong.

My recovered RPi3 didn't get an "HP" icon at the top of the window when I installed HPLIP this time. I have to communicate with the printer via CUPS! And I don't remember having to connect to the printer via USB before I crashed my original OS install.

Sometimes if I leave the RPi3 running unused for a few hours it will die. This of course prevents proper shutdown via the "Shutdown..." command under the raspberry. When next booted it flashes very low resolution text across the top of the screen, and then flashes a small window too small and short-lived for me to see what it's all about, before getting one with a reboot, normal except extremely slow. Next time will be OK, if I shut down properly, although my impression is that this new install runs slower than my old one did. (But I keep forgetting to look up how to speed the thing up; maybe that's the problem.)

The weirdest thing is that if I click on the ejection arrow in the upper right corner, it will list "SL32G (SETTINGS)." I can go ahead and "eject" and be told that it is now safe to remove it, whatever and wherever it is. Thenceforth when I click on that arrow, the "SL32G (SETTINGS)" will be ghosted, and no longer ejectable. I wonder if I have somehow contaminated the OS card, and whether I can or should fix it.
