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:
For me this came down to the /usr/lib/x86_64-linux-gnu/opera/libffmpeg.so file being at the wrong level.
The story goes that Opera is based off Chromium and so relies on the libffmpeg.so version associated with Chromium. Somehow the version that is included with Opera on Ubuntu 18.04 (and 16.04 as well) is actually the wrong version. As videos depend on it then they don’t work in Opera straight out of the can.
The work round is simple and worked seamlessly for me with both 16.04 and 18.04.
If you are paranoid (like me) rename the existing libffmpeg.so in /usr/lib/x86_64-linux-gnu/opera to something else (aka libffmpeg.so.18.04-orig or whatever you like)
sudo mv /usr/lib/x86_64-linux-gnu/opera/libffmpeg.so /usr/lib/x86_64-linux-gnu/opera/libffmpeg.so.18.04-orig
Then copy over the chromium version to the Opera directory.
sudo cp /usr/lib/chromium-browser/libffmpeg.so /usr/lib/x86_64-linux-gnu/opera/libffmpeg.so
Now videos should work.
BE WARNED: If you fixed this on Ubuntu 16.04 and then upgraded to Ubuntu 18.04 the fix has to be done again as the upgrade tramples over the fix.
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 reading
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:

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. Continue reading
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.

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 reading
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. Continue reading
