Publish topic guides to the wiki and document tabbed windows
Publish the guides from this repository to the GitHub Wiki. Organize them into Usage, Configuration and Development, with 15 separate configuration topics and redirects for the former website guide URLs. Add a tabbed-windows guide covering grouping, switching tabs and taking windows out. Document the scrolling indicator's defaults and limits, and link the guide from the README, shortcuts and IPC pages. Update from main, including the latest tabbed-layout changes. Separate Activities setup, configuration and publishing documentation. Review the guide prose with the unslop skill, keeping existing examples and heading links. The wiki workflow uses GitHub's built-in token to publish documentation changes on main. Validation: - 20 documentation tests pass, including README links and Activities/tab-indicator field coverage. - The publisher builds 46 wiki pages; the site build and Python syntax checks pass. - All 115 code examples from main are preserved. - The Python suite passes: 90 tests passed and 31 opt-in integration tests skipped, with the system GI module available.

# Displays
|
||||
|
||||
Each `output-profile` needs a unique, nonempty `name` and at least one `output`
|
||||
entry. A profile matches when every required monitor is connected and its
|
||||
optional `lid-closed` condition matches. The profile with the most required
|
||||
monitors wins; ties use config order. If none matches, Ferese extends across all
|
||||
usable connected monitors. Find selectors with `feresectl outputs`.
|
||||
|
||||
| `output-profile` key | Type | Default |
|
||||
| --- | --- | --- |
|
||||
| `name` | unique nonempty string | required |
|
||||
| `layout` | `internal-only`, `external-only`, `extend`, `mirror` | `extend` |
|
||||
| `lid-closed` | boolean | either lid state |
|
||||
| `mirror-source` | selector of an enabled output in this profile | first enabled hardware key |
|
||||
| `lid-policy` | `dock-or-suspend`, `ignore` | `dock-or-suspend` |
|
||||
| `confirm-timeout` | seconds; `0` disables confirmation | `15` |
|
||||
|
||||
| `output-profile → output` key | Type | Default |
|
||||
| --- | --- | --- |
|
||||
| `match` | nonempty connector or persistent identity string | required; unique within profile |
|
||||
| `required` | boolean | `true`; set `false` for an optional monitor |
|
||||
| `enabled` | boolean | `true` |
|
||||
| `mode` | `"WIDTHxHEIGHT"` or `"WIDTHxHEIGHT@HZ"` | Preferred mode |
|
||||
| `auto-refresh` | boolean | `false` |
|
||||
| `scale` | number > 0 | `1` |
|
||||
| `transform` | enum below | `"normal"` |
|
||||
| `position` | `[integer, integer]` | Automatic horizontal placement |
|
||||
|
||||
Transforms: `normal`, `rotate-90`, `rotate-180`, `rotate-270`, `flipped`,
|
||||
`flipped-90`, `flipped-180`, `flipped-270`. In extend and mirror profiles,
|
||||
unlisted monitors stay enabled with defaults. Internal-only and external-only
|
||||
filter by connector type. A layout that would disable the final usable display
|
||||
falls back to a working display. Profiles that explicitly disable all their
|
||||
listed outputs are invalid.
|
||||
|
||||
Monitor identities use EDID manufacturer, product/model and serial, rather than
|
||||
a hash of the entire EDID. Without a usable serial, the identity includes the
|
||||
GPU's sysfs hardware path and connector. For duplicate serials, Ferese adds the
|
||||
same path and connector to distinguish the monitors. If both arrive together,
|
||||
both identities include those details. If the second arrives later, the first
|
||||
keeps its identity and only the second gets the path and connector. Ferese
|
||||
remembers that choice for the compositor session. Without serials, Ferese
|
||||
identifies monitors by port and cannot tell them apart if you swap their ports.
|
||||
Connector names and old `drm-edid:` selectors still work. Ambiguous or
|
||||
overlapping selectors are rejected during live reload. A disconnected identity
|
||||
can remain in config; it prevents matching only when its entry has
|
||||
`required=#true`.
|
||||
|
||||
```kdl
|
||||
output-profile "desk" layout="external-only" {
|
||||
output "DP-1" mode="2560x1440@60" scale=1.25
|
||||
output "eDP-1" required=#false enabled=#false
|
||||
}
|
||||
|
||||
output-profile "mobile" layout="internal-only" {
|
||||
output "eDP-1" scale=1.75
|
||||
}
|
||||
|
||||
output-profile "presentation" layout="mirror" mirror-source="eDP-1" {
|
||||
output "eDP-1" scale=1.75
|
||||
output "HDMI-A-1" mode="1920x1080@60"
|
||||
}
|
||||
```
|
||||
|
||||
Mirror uses the source's logical size, workspace, layers and pointer. Targets
|
||||
own no workspaces or separate pointer region. Ferese fits the complete source
|
||||
into each target's transformed physical mode, preserving aspect ratio and
|
||||
letterboxing instead of cropping. Target scale does not resize the source
|
||||
layout. Each target has its own hardware cadence; only the source releases
|
||||
client frame callbacks and presentation feedback. Mirrored monitors are listed
|
||||
by `outputs`, but expose one logical output to clients and the shell. If a required mirror target disconnects, Ferese selects another matching
|
||||
profile or extends across all usable connected monitors. Leaving mirror
|
||||
restores evacuated workspaces.
|
||||
|
||||
```sh
|
||||
feresectl outputs
|
||||
feresectl output-profiles
|
||||
feresectl toggle-display-mode
|
||||
feresectl output-layout extend
|
||||
feresectl output-profile presentation
|
||||
feresectl output-confirm
|
||||
feresectl output-profile auto
|
||||
feresectl output-internal off
|
||||
feresectl output-revert
|
||||
```
|
||||
|
||||
The display Fn key (`XF86Display`) and the bar’s display icon open the same
|
||||
display-mode chooser. The icon appears while an external monitor is connected.
|
||||
`output-layout` selects a layout without requiring a named profile and keeps
|
||||
the matching profile’s mode, scale and transform settings.
|
||||
|
||||
A manual choice overrides automatic selection until the monitor set or lid
|
||||
state changes. Reload keeps it only if its profile still exists and matches.
|
||||
Manual changes revert after `confirm-timeout` seconds unless confirmed;
|
||||
`output-revert` restores immediately. Reverting restores the last confirmed modes,
|
||||
scales, transforms and positions, even if you make several changes before
|
||||
confirming. The timeout still applies if the client that made the change exits. Automatic hotplug/lid changes never wait for confirmation.
|
||||
Disabling the last usable internal panel is rejected.
|
||||
|
||||
```kdl
|
||||
output-profile name="docked" {
|
||||
output match="HDMI-A-1" scale=1.5 {
|
||||
position 0 0
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Settings → Displays offers the connected display's supported refresh rates at
|
||||
its configured resolution. Choosing a rate saves it and disables Auto. Choosing
|
||||
Auto saves the highest supported rate as the normal mode and enables automatic
|
||||
switching. These choices apply immediately for the active profile and persist
|
||||
across restarts.
|
||||
|
||||
With `auto-refresh=#true`, a discharging system battery below 30% switches the
|
||||
display to a supported mode within 1 Hz of 60 Hz at the same resolution. The
|
||||
configured normal mode returns on external power or when the battery reaches
|
||||
35%. Power is checked every five seconds; mode changes only run when the policy
|
||||
changes. Unavailable battery data restores normal refresh. If no matching 60 Hz
|
||||
mode exists, normal refresh is retained. Rejected DRM mode changes retain the
|
||||
current output. A refresh-rate change can briefly blank the display (about one
|
||||
second on some panels), including automatic changes below 30%, recovery at 35%,
|
||||
and restoration on AC. Session activation refreshes lid and connector state
|
||||
before rendering; unchanged outputs retain their handles and workspaces.
|
||||
Hotplug bursts settle for 150 ms before one reconciliation. Ferese records changes that arrive while the session is inactive and applies
|
||||
them on activation.
|
||||
|
||||
```kdl
|
||||
output-profile laptop {
|
||||
output eDP-1 mode="2880x1800@120" scale=1.75 auto-refresh=#true
|
||||
}
|
||||
```
|
||||
|
||||
With a usable external display, closing the lid disables internal panels after
|
||||
external activation succeeds. Without one, Ferese asks logind to suspend,
|
||||
respecting sleep inhibitors. `lid-policy="ignore"` disables this behavior for
|
||||
the selected profile. Resume reads lid state from logind, with ACPI fallback,
|
||||
before reconciling fresh hardware. Ferese releases its logind lid inhibitor on
|
||||
session pause, so logind handles the lid while another session or TTY is active.
|
||||
Workspaces keep their home output and return when it reconnects, unless you
|
||||
reassigned or deleted them after evacuation. Floating
|
||||
windows are remapped and clamped to the surviving display.
|
||||
|
||||
On atomic DRM, Ferese tests the complete configuration for each GPU before
|
||||
changing it.
|
||||
Smithay performs the real commits; logical changes follow successful hardware
|
||||
application. Failed commits attempt restoration, and outputs that cannot be
|
||||
restored are removed from logical state. Each GPU commits separately. If a later GPU fails, Ferese attempts to restore
|
||||
the earlier GPUs. Legacy KMS lacks atomic
|
||||
test-only validation. Hardware failures can still leave the session without a working monitor; Ferese tries preferred modes to recover a display instead of
|
||||
intentionally turning off the last working one.
