Q Where does print screen (ps) get the data it places on the clipboard? If the screen image is a jpeg file, say from a 10 megapixel camera, is the whole file, full resolution, loaded into vm? and if I do a ps, will the clipboard be handed the full resolution file?
A I can't answer your specific question, but I can assure you that the resolution of print screen will be the resolution of your monitor. (I've pasted many print-screens into GIMP.)
Here's some trivia for you: the different flavors of Ubuntu have different print screen programs! I use Xubuntu; a Kubuntu user might give you a different answer.
Q Is there any way to go directly back to Desktop from suspend?
A Yes, if you don't lock the screen. I have a laptop with that setting; I close the laptop, it suspends. I open it, and it resumes where it left off.
Q Is it possible to upgrade Ubuntu MATE 17.10 Beta to Ubuntu MATE 17.10 Stable (when it comes out later) without reinstalling?
A (Thanks to oldfred in the Ubuntu Forums) You do not have to do anything. Normal updates will update it to the current version.
But as the development version, it has installed many apps, perhaps multiple times, many kernels and changed many settings. So log files may already be larger than normal. If you are good at house-cleaning, then you should be ok, but I prefer to just reinstall so everything starts fresh.
Q I'm new to Linux and I'm running Ubuntu Studio in hopes of being able to run all the programs I used to run on Windows. Right now, I'm trying to set up DaVinci Resolve, which has a Linux version. I follow the steps from this link here: https://www.thefanclub.co.za/how-to/how-install-blackmagic-design-davinci-resolve-125-ubuntu-1604-lts
After completing the steps, the icon shows up on the desktop, but when I double-click to open it, nothing happens.
A The installation instructions are quite complicated. Coming from Windows, the most likely problem is that somewhere, you typed a letter in the wrong case.
In Linux, Downloads and downloads are completely different places.

Tips and Techniques
Backup revisited
In issue 115 of Full Circle Magazine, I mentioned that I was using (free) Crashplan Home to back up my home folder. It worked OK, the biggest issue was that my file server would not automatically reconnect when I rebooted the router.
Recently, Crashplan announced that they would be removing Crashplan Home from their product lineup, effective late next year. My hat is off to them for giving lots of notice that I need to find a new approach. Thanks, guys!
For now, my crummy router is still giving me grief, but next month I hope to write about how I switched to rsync.
