Read-only file system error trying to install MangoHUD

I downloaded the latest release of MangoHud and tried to install it using the "./mangohud-sh install" command, after extracting it to a subfolder within the download folder. I get a bunch of errors saying the system is read-only. I assume I need to input some sort command to make it not read-only. Not being a Linux user I don't understand why I can't just double click a download executable to install a tiny app. Lol?

Solution:

Using text files to configure things is standard practice in Linux, not too dissimilar from opening up a game's settings manually in regular PC gaming.

MangoHud is pre-installed with Bazzite Universal Blue images are Atomic, so any system level modifications have to be done through either a custom image setup or package layering. As I said though, MangoHud is pre-installed - so you just need to enable it in-game as one usually does

Installing and Managing Software on Bazzite

Hi, Brew and Fleek are part of the upstream Universal Blue images.

how do I access it? When I search for MangoHud on the Applications screen in desktop mode, it finds nothing. If it's pre-installed one would think it shows up as an installed app, and can be opened, configured, etc. while outside of gaming mode. This is one of the issues I have with linux, the most basic things are not at all obvious.

You need to enable it by setting MANGOHUD=1 %command% in the game's launch arguments It can be configured through text files in ~/.config/MangoHud as per the MangoHud README on GitHub The global one is MangoHud.conf, individual games are the name of the executable + .conf. Proton/Wine games are the name of the executable without the .exe extension, with a wine- prefix. MangoHud isn't a graphical application, which is why you can't launch it in your application drawer. There is a separate project with a graphical interface to configure it called GOverlay, but it can break your system, which is why it was removed from Bazzite.

Here's what my MangoHud.conf looks like, as an example:

preset=2
no_display
af=16
fps_limit=141
vsync=2
gl_vsync

preset=2
no_display
af=16
fps_limit=141
vsync=2
