DeckLock v0.3.6

DeckLock 0.3.6

Added

• The login can have its own background pool, slideshow interval and layout,
  through a [login] section with same_as_lock = false
  (decklock config set login.same_as_lock false, login.layout.clock_visible,
  login.background_pool). With same_as_lock, the default, the login shows what
  the lock screen shows, as before, and the file keeps no [login] section. Rest
  stays one for both screens. Login setup migrates the login's media to the shared
  library like the others and fails before migrating anything if one is unreadable.
• Settings have three tabs: Lock screen, Login and Rest. Lock screen holds its
  pool, interval and layout; Login holds "Same as the lock screen" (on by default)
  and, when off, its own pool, interval and layout; Rest is unchanged and applies to
  both screens. Each layout has its own "Restore defaults". The preview shows the
  screen of the open tab, the login included, in an ordinary window. "Layout and
  preferences" keeps the options shared by all screens.
• "Apply to login" in the Login tab saves the settings and applies them to the login
  screen through polkit: the session's authentication agent asks for the
  administrator password, which DeckLock never sees. It runs the new
  decklock setup login-appearance, which refreshes only the login's appearance and
  media and refuses a login that does not use DeckLock; the greetd command,
  compositor, keyboard and controller stay as they are. Packages install a polkit
  action limited to /usr/bin/decklock setup. Without a polkit agent (common on
  Hyprland, Sway, labwc or Wayfire) or without pkexec, the button shows the terminal
  command instead. Setup run through pkexec finds the desktop user like sudo does.
• The lock, login and preview screens show the battery level on devices with a
  system battery, in the top-right corner on its own row above the power buttons.
  That row spans the width, so the help button in the top-left corner lines up with
  the power buttons below it; without a battery the row takes no space. It is read
  from the Linux power-supply class every 30 seconds; mains adapters and the
  batteries of peripherals such as a controller are ignored. Rest mode hides it
  together with the power buttons, and the settings preview shows it like the lock
  screen. Themes style it through CSS: #battery, its image and label, the icon
  size with -gtk-icon-size, and the .low (20 % or less, not charging) and
  .charging states. Margins on #battery move it within its row, and margins on
  #top-bar move the whole top bar.
• Layout option "Show battery percentage" (layout.battery_percentage, on by
  default); off shows the battery icon alone, with the level in its tooltip.
• The lock screen, login and preview have a question-mark help button in the top-left
  corner. It opens one short page in plain words, about unlocking or signing in,
  inside the screen itself: a session lock shows no other window. F1 opens it too,
  and Esc or its × close it. The full guide stays in settings.

Changed

• The login no longer shows a "DeckLock — Login" title; its help button takes the
  top-left corner. Help buttons in every window are a plain question mark, which no
  longer depends on the icon theme. The preview's help button opens the short lock
  guide instead of the full guide.
• The preview no longer shows a "Wayland · Preview" banner; it looks like the lock
  screen. Its window title and the notice shown on submit still say it is a preview.

Fixed

• decklock setup status recognizes a login generated for Hyprland, which starts
  DeckLock from its Lua file; it reported it as not configured.
• The A button confirms like Enter while the on-screen keyboard holds the controller,
  at login and on the lock screen. The keyboard captures A along with the other
  buttons and ignored it, so with the keyboard open the password could only be sent
  with the keyboard's own Enter key, or by hiding the keyboard and clicking.

Compatibility and limitations

• "Apply to login" needs polkit's pkexec and an authentication agent in the
  session. GNOME, KDE Plasma, Xfce and Cinnamon bring one; on Hyprland install and
  start one such as hyprpolkitagent. The real polkit dialog and a root write to
  /etc/greetd through pkexec are not exercised by the suites, which use a fake
  pkexec and run login setup as root through sudo.
• The A button with a physical controller, the battery on real hardware and the
  login help on a Steam Deck login remain outside what the suites establish.
