I had a few problems getting my in-built microphone to work when using Audacity to record voice.
It all came down to a matter of settings.

I needed to store my Linux-Ubuntu notes somewhere where I could get at them wherever I was.
Then it came to me. Why not stick them up on a website?
Which I duly did. Here they are.
Opera on Ubuntu 18.04 and 16.04 won’t play videos – Simple Fix
If you install Opera on Ubuntu 18.04 (or 16.04) it all works – except for video playback. When you first install Opera (or upgrade Ubuntu) You (or at least I) get this:

Here’s my notes on mounting a USB drive that for some reason fails to mount automatically on Ubuntu.
This would be the case if you plugged in the usb stick and it has not appeared in the “places” tag in the menu bar.
Open a terminal. If you are running in the Gnome GUI you can do this with crtl-alt-t but use whatever method you like.
Continue readingUbuntu: start or stop MySql and Apache2 on boot
These are my personal notes on enabling/disabling auto start of Mysql and Apache2 on boot (or other services for that matter). Also on how to start/stop these services after boot. The notes are as they are. I hope you find them useful.
All this is done through a terminal. Open one from the Gnome GUI with:
Ctrl-Alt-t

Want to see what memory is fitted to your laptop or PC? Or if your machine has any vacant memory slots? Or maybe just to see what the speed and type of memory you already have and where it is?

Just in case anyone else does this or has a similar problem here’s how I managed to end up with a readonly filesystem and how I (eventually) fixed it.

Here’s my personal notes on resetting the root password for a MySql or MariaDB database running on Ubuntu Linux. Maybe it’s useful to you too.
I assume the machine is running a gnome desktop manager.
Open a terminal with ctrl-alt-t or do whatever you need to open a terminal.

Here’s my personal notes (wordpressed up) on reducing video file size using tools on an Ubuntu Linux Distro.
Last post (here) I showed how to change the format of video files from (say) mp4 to (say) mpg. That’s all fine for converting files. But what if you want to crush down your mp4 or mpg file and make it smaller?
Continue readingHow to Convert video file format.
Here are my notes on how to convert video files between mp4 and other file types on Ubuntu. Especially between mp4 and mpg but avi and wmv can be used too.
There are a number of GUI converters in Linux but I’ve always found the command line converters the best. In fact most of the GUI solutions are just front ends on these command line driven converters. GUI tool winff isn’t bad but using command line tools (either avconf and ffmpeg) give you more options.

Here’s my personal notes on restoring a Ubuntu (or other linux distro) wifi connection that has gone missing. Maybe they’ll be useful to you too.
Sometimes when Ubuntu comes out of suspend or even after booting from power-on the wifi connection disappears. Usually the little triangular wedge on the task bar is empty. Usually this is easy to fix.
