A few years ago I asked a question to one of those user groups, and I received no answer. Do not remember the issue, so I must have worked around the problem[s] myself.
Hopefully, whichever group I looked into, will be more responsive to "newbie" questions, or those that are from a "regular" user with no experience with the issues/problems I had.
Personally, I never heard of "RecordMyDesktop", by name, before. Though I remember seeing a few weeks ago some other package name that does that type of function. So, do you have to use that package or can you use some other one?
I run Ubuntu as my default desktop OS since version 9.04 or 9.10. That desktop is currently running 14.04LTS, while my laptops [3 now] run 16.04LTS. All 3 laptops dual boot to Win10 [currently] Since I rarely turn on the desktop anymore, I use the newest laptop [17.3 inch display with 1TB drive] as my default system. [desktop has a 22 inch monitor with 6.25TB of internal drives]
