Solution to Unity Desktop Fullscreen Graphical Glitch

You may find that your out of the box installation of Unity Desktop has the following glitch:

  3. Do something on the other screen e.g. focusing or maximising a window
The exact actions that cause an issue aren't very consistent.

Solution:

  1. Install CompizConfig
  2. Utility → Workarounds
  3. Set "Force full screen redraws (buffer swap) on repaint" to true.

Use Joycons with Steam on Linux

Steam appears to support Joycons. They connect individually but not as a single combined controller. There is a toggle in Steam > Settings > Controller for combining Joycons, but it doesn't do anything. The UI here is also a bit weird because the button appears twice. Looking online there is a suggestion that you need Steam Beta. This doesn't make a difference. The solution was to install this driver: https://github.com/DanielOgorchock/joycond After installation, when you connect a Joycon or Pro Controller, you tap the L and R buttons to tell the driver how your controllers are combined. Now steam recognises it as a single controller. However you will need to connect the controller this way before you start Steam (even for your Pro Controller, which you previously would not have needed to do).

Dynamically Update DNS When Your Server IP Address Changes

I've been running my website on a Raspberry Pi in my home for years. Whenever my router got restarted, my home would have a new external IP address, and so I needed to find out that IP address, then log into the registrar I use and update the IP address to direct my domain name to my website server. My website didn't really need to be live most of the time, so it didn't bother me occasionally changing the IP address. Recently, I was thinking it must be possible to automate logging into my account and changing the IP address. So I looked up to see if someone had already made a solution, and it turns out there is a standard one. It's called dynamic DNS. Make sure your domain registrar supports dynamic DNS. You can move your domain to another registrar if not. Install ddclient on the server. This is one of several options of software which performs dynamic DNS updates to domain providers. It may not support all registrars. Configure your domain in your registrar to use a ...

Fix Controller Input when a Game Doesn't Use Steam Input

Background Knowledge Steam Input is an interface for developers to use the controller configuration built into Steam for their games. It is entirely optional and not all games use it. Steam gives you the option to enable and disable Steam Input on a per game basis. Steam has controller button mapping for in-game, Big Picture Mode, and on desktop (outside of games), and mappings for individual games. By default Steam will give certain controllers a desktop mapping that lets you move the mouse and bring up an on-screen keyboard, which is not what you want in a game. If you press F11 in a game and Steam Overlay doesn't appear and you have it configured to appear, Steam thinks that you are not in a game, and therefore it will use the desktop mapping instead of the in-game mapping. Steam Input works by capturing inputs from your controller, suppressing them from the rest of your system and emitting the inputs that you desire instead to the rest of your system. Problem If you are playin...
