# WindowMaker and FDS Control

WindowMaker provides the FDS desktop. Its default appearance is grayscale on
all displays: white backgrounds, black borders and selected titles, gray widgets,
Terminus text, and no animations. No E-Ink monitor detection or special cartridge
is needed to select this theme.

## Open the desktop

At the FDS console:

```sh
fds profile activate windowmaker
fds profiles
```

FDS opens a terminal and **FDS Control**. You can reopen the panel from the
WindowMaker root menu's **FDS Control** item, or run `fds-control` in a terminal.
An ENVIRONMENT cartridge requesting the `windowmaker` profile can also start
the desktop. The Dasung controller runs independently of this session.

## Manage cartridges in the panel

1. Select a bay in the left column. The right column shows its identity, state,
   running process count and available software commands.
2. Select a command, then choose **Run in terminal**. The terminal stays open
   after the command exits so you can read its output; close it when finished.
3. Choose **Safe eject** to stop that bay's programs and release its storage.
   Wait for **SAFE** before removing the cartridge.
4. Use **Rescan** to refresh discovery. The panel also checks for changes
   automatically and updates the display when the visible state changes.

For an inactive DATA cartridge, the primary button becomes **Use DATA**. Activate
it there to make it available at `/data`; eject another active DATA first.

Errors appear in the status area. Actions are unavailable when their prerequisites
are missing, such as running an application from an empty bay or ejecting the
active SYSTEM. The panel uses the same cartridge service as `fds`.

Keyboard controls: **Tab** moves focus between bays, programs and buttons;
**Up/Down** changes the selected bay or program; **Enter** activates the focused
control; **R** rescans; **Esc** closes the panel. Closing the panel does not eject cartridges or close
application terminals; use Safe eject when you want to release a cartridge.

## Return to the console

Choose **Return to console** in the root menu, or run:

```sh
fds profile deactivate
```

This closes the desktop session. It does not shut down FDS. Use `fds poweroff`
when you want to turn the computer off.

## Customize the appearance

System defaults are installed in `/etc/WindowMaker/`. Your files in
`$HOME/GNUstep/Defaults/` override those defaults. The session copies the FDS
settings into a new home once and preserves existing preferences. Use
WindowMaker's settings tools or edit those preference files to change fonts,
colors and behavior. Plain `wmaker` also reads the FDS system defaults.

The root menu includes Ethernet on/off controls. Equivalent console commands
are `fds network on`, `fds network off`, and `fds profiles` to inspect the result.
