Misc notes for fixes and other things I don't want to lose

Patching `nixpkgs`¶

https://github.com/NixOS/nixpkgs/pull/142273#issuecomment-948225922

https://github.com/NixOS/nix/issues/3920#issuecomment-681187597

Patching GNOME extensions¶

The entrypoint for a patch is extensionOverrides.nix. The file also provides many good examples to tackle common issues.

You probably want one of the replacement functions. Schema issues need a few extra lines.

Older reference examples:

Extracting data for declarative firefox search engines¶

Use dejsonlz4 to extract your current settings, and tweak it to fit home-manager's programs.firefox.profiles.<name>.search

ZSH is slow to start¶

When using enable = true in both nixpkgs and home-manager zsh slows down a bunch due to duplicate calls to compinit. In my case I just disable the home-manager option.

nix-community/home-manager#3965

Fix home-manager's home.sessionVariables not being sourced on DE's¶

For when you want to sell your soul to the devil

Old¶

These are probably not relevant anymore due to updates/fixes, but keep them just in case

Flatpak access to fonts¶

NixOS/nixpkgs#119433

https://github.com/accelbread/config-flake/blob/744196b43b93626025e5a2789c8700a5ec371aad/nix/nixosModules/bind-fonts-icons.nix#L9

Non Nix specific¶

AMD Pstate EPP¶

Interesting options to play with can be found in

/sys/devices/system/cpu/cpu{num}/cpufreq/

Kernel 6.4 apparently brings a new guided mode, should see how that behaves

Power profiles daemon¶

powerprofilesctl - launch is an interesting subcommand
