mainframe has no desktop and the only connected output hangs off the Intel
iGPU, while the RTX 3060 that encodes drives no monitor. Capturing the real
output would copy every frame between GPUs. So: a minimal sway session on
the headless wlroots backend, pinned to card0, with one 1920x1080 virtual
output for Sunshine to capture. Verified end to end — Sunshine finds
zwlr_screencopy_manager_v1 and creates h264_nvenc and hevc_nvenc.
(av1_nvenc fails because Ampere has no AV1 encoder; that is expected.)
Two things had to be fixed to get there. The installed sunshine-git was
built against boost 1.89 against a system now on 1.92 and could not load
five libraries — which is why the service had been enabled but never once
run. Replaced with sunshine-bin, which is current and prebuilt.
And Sunshine now gets a unit of ours rather than a drop-in: the source AUR
package ships sunshine.service while -bin ships
app-dev.lizardbyte.app.Sunshine.service, so a drop-in silently stops
applying the moment you switch between them.
apps.json replaces the stock file, whose "Low Res Desktop" entry shelled
out to xrandr and would have done nothing on Wayland.
The earlier survey grepped for the exact package name and concluded the
binding in hyprland.conf was dead. It is not: system76 has it from AUR as
networkmanager-dmenu-git, and the work laptop carries the upstream script
in its own bin. The $mainMod+W binding already works on both.
Adding the repo package to system76.pacman would have made pkg-restore
install it alongside the AUR one — both ship /usr/bin/networkmanager_dmenu,
so pacman would have refused with a file conflict.
Replaces the previous repo, which had split into two histories that never
met (mainframe on a dead GitLab remote, the laptops on Gitea) with 146
dirty files across three machines and the NAS never enrolled at all.
Branch-per-machine is gone. One main, with host differences expressed as
small files under hosts/<hostname>/ rather than as branches, so there is
nothing to merge. The reconciled zsh layer reduces 15-33 line forks to
1-7 effective lines per host; distro differences (oh-my-zsh prefix,
syntax-highlighting path, fd vs fdfind) are probed in common/ instead.
Fresh history: the old one carried six plaintext credentials, 45 MB of
mail caches, browser caches and vendored binaries. 5,096 tracked files
and 144 MB become 462 files and 2.6 MB. The .gitignore is now an
allowlist, which is what keeps that true.
Root cause of the rot: ~/.local/bin was a symlink to scripts/ with GOPATH
inside it, so every go install wrote into version control (2.2 GB on the
work laptop). PATH now points at the repo instead of the reverse.
Also: Hyprland replaces sway and is sourced in two halves so $browser is
defined before use; singleton automations carry ConditionHost= alongside
host-layer-only placement; ddns moves from cron to a guarded timer;
package manifests and pkg-snapshot/pkg-restore replace the X11-era
install_scripts/; networkmanager-dmenu added to system76 (the binding
always existed, the package never did).
