Workspaces were pinned one-per-monitor, so switching only ever moved one
screen. The virtual-desktops plugin replaces them with vdesks that span
every monitor, and SUPER+1..5 now switches all screens together. Hyprland
plugins are ABI-locked to the compositor, so the input's nixpkgs follows
ours to compile against the hyprland we actually run. cycleworkspaces
stays off: upstream says it breaks above 2 monitors, and pc has 3.
The session had also been dying several times a day, which looked like a
Hyprland crash and was not one. There was no swap at all, and a
nixos-rebuild forks ~60 nix evaluators; stacked on a browser and a few
editor sessions that exhausted all 15G, leaving page cache squeezed to
40M while 13G sat in anon and nothing was reclaimable. The kernel then
OOM-killed 1Password (highest oom_score_adj), and because every GUI app
shares the wayland-wm@hyprland.service cgroup, systemd's default
OOMPolicy=stop tore down the whole unit -- compositor included, with
uwsm's Restart=no meaning nothing came back.
Two independent fixes: zram swap (50% of RAM, zstd) with vm.swappiness
raised to 180, so the kernel compresses anon pages instead of evicting
cache, which raises the ceiling; and OOMPolicy=continue, so that hitting
it costs one app instead of the desktop. zram rather than a swapfile
because root is compress=zstd, and a btrfs swapfile needs its own
nodatacow, uncompressed subvolume.
Also lands the pending work in this tree: hyprshot replaces grimblast for
screenshots (it reads HYPRSHOT_DIR, not XDG_SCREENSHOTS_DIR, so shots were
landing loose in ~/Pictures), hyprlock at boot so login lands on the lock
screen and unlocks the keyring, the battery popup moves to SUPER+R, and
SUPER+W/E open floating wifi and bluetooth panels.
