Prohlídka Xfce 4.20

Tato prohlídka Vám představí hlavní nové funkce Xfce 4.20. Zahrnuje pouze vylepšení provedená na (uživatelsky viditelném) povrchu.

Pro podrobný seznam změn si prohlédněte kompletní protokol o změnách v Xfce 4.20.

General

Wayland

Důležitá poznámka: Mějte na paměti, že podpora systému Wayland v Xfce 4.20 je experimentální. Je doporučena pouze pokročilým uživatelům, protože se můžete setkat s chybami a nekompletní funkčností. Postupujte s opatrností!

Díky Brianovi a Gaëlovi jsou téměř všechny součásti Xfce schopny běžet pod systémem Wayland se současnou podporou X11.

Tento významný krok byl dosažen abstrahováním specifických volání pro okenní systémy X11/Wayland a využitím protokolů Wayland/Wlroots. Během tohoto procesu byla vytvořena zcela nová knihovna Xfce libxfce4windowing. Pro provoz přenesených komponent Xfce nebude vyžadován XWayland.

Xfce zatím nenabízí kompozitor, který by podporoval Wayland. Pokud chcete spustit Xfce v systému Wayland, nejlepší výsledky vám poskytnou Labwc a Wayfire. Podrobné pokyny k tomuto postupu naleznete zde. Mějte prosím na paměti, že podpora Waylandu je stále experimentální!

Plánuje se přidání podpory systému Wayland do Xfwm4 při zachování stávající funkčnosti pro X11. Taková restrukturalizace však bude velmi náročná a zatím nemůžeme říci, kdy (a zda vůbec) bude dokončena, takže prosím nečekejte s napětím.

U několika komponent a více funkcí nebylo převedení na systém Wayland možné, částečně proto, že dosud neexistují standardizované protokoly systému Wayland, které by poskytovaly potřebné služby:

• Podpora pracovních ploch chybí (protokol ext-workspace byl právě sloučen).
• Ikony systémové oblasti budou chybět několika aplikacím (které vyžadují nástroj StatusNotifier místo GtkStatusIcon)
• Xfce4-settings: Keyboard and mouse settings so far are internal to the Wayland compositor and as such the according Xfce dialogs won’t be available on Wayland yet.
• Power related keyboard handling (brightness keys, suspend, etc.) is internal to the Wayland compositor and as such cannot be supported yet by Xfce components.
• Wayland does not specify a native protocol for taking screenshots. However, xfce4-screenshooter already supports screenshots via the wlroots ‘screencopy’ protocol (entire screen). Screenshots of a rectangle selection or the active window are not yet supported via Wayland.

Some other Xfce components don’t run at all on Wayland:

• Xfwm4
• Xfdashboard
• Xfce4-screensaver (porting to Wayland completed but not merged, as it requires the experimental libwlembed library)
• Xfce4-windowck-plugin (needs to be ported to libxfce4windowing)
• Xfce4-xkb-plugin (keyboard handling is internal to the Wayland compositor)

More detailed info on the current Wayland status can be found on our Wayland roadmap.

Scaling

Icons and thumbnail scaling was fixed for various components. Various missing icons for larger scales were added. Any blurriness when using Xfce components on a HiDPI display should be gone now.

exo

Icon View Performance

By using different container types, the “Exo-Icon-View” now can handle 100,000 files and more without freezing.

Type ahead search box

The type ahead search box in the exo icon view now always stays inside the according view widget.

libxfce4ui

Editor klávesových zkratek

Klávesové zkratky nyní lze použít k více akcím, pokud mezi sebou nekolidují.

Dialogové okno O aplikaci

Dialogové okno nyní zobrazuje logo distribuce, informace o použitém systému oken a použitou grafickou kartu.

libxfce4windowing

Tato knihovna je v Xfce nová. Libxfce4windowing je abstakční knihovna, která se snaží prezentovat koncepty oken (obrazovky, okna na horní úrovni, pracovní prostory, atd.) v nezávislém systému.

Aktuálně je X11 podporováno prostřednictvím libwnck. Systém Wayland je částečně podporování pomocí různých rozšíření protokolu Wayland. Plný rozsah operací dostupný na X11 ale na systému Wayland podporován není kvůli chybějícím funkcím v rozšířeních těchto protokolů.

thunar

Připojená a vzdálená umístění

U přípojných bodů se nyní zobrazí emblém a mají specifický typ popisu.

Ipv6 remote URLs are now supported.

It is now possible to create symbolic links as well on remote locations.

Search

It is not required any more to wait until a search is finished to open the context menu on search results.

Toolbar

A couple of new toolbar buttons were added:

• View Switcher - A drop-down button to select a view.
• Menu - This hamburger button will show automatically in the toolbar, when the menubar is hidden. It will reveal a vertical menu, bar, when pressed.
• New Tab - Open a new tab using the current directory.
• New Window - Open a new window using the current directory.

On shrinking the Thunar window, toolbar items will now be moved to an overflow menu. Like that, it is possible to maintain smaller thunar windows.

Furthermore, a bug was fixed which prevented the usage of submenu custom actions in the toolbar.

Window Decorations

There is now an option to use client side decorations in Thunar (CSD).

Statusbar

An option to show the number of hidden files in the statusbar was added.

Recently Used Files

Only files which were successfully opened are now added to the list of recently used files.

Directories won’t be added to the recently used files anymore.

Symbolic Icons

There is now an option to use symbolic icons in the side pane and colored icons in the toolbar.

Drag and Drop

While dragging files, folders are now opened automatically on hover.

While dragging files, the focus of the split view pane is now updated when hovered.

Performance

In the past, you might have faced situation involving bigger numbers of files in which thunar showed a freeze. Due to various different performance measures, thunar now is much more bullet-proof for action involving huge numbers of files.

This was achieved by using appropriate container types, moving some actions into separate jobs and throttling of view-updates.

A number of integration test cases will be used in order to keep performance on the current level in the future.

Custom Actions

Shortcuts for custom action will now as well work when the custom action is located in a sub-menu.

File Transfer

For file validation in thunar 4.18.x a md5 checksum was calculated for source and target file. This calculation turned out to be rather slow and actually superfluous. Now files are just compared directly. In addition, the usage of direct I/O operations now attempts to prevent comparison of possibly cached buffers.

An option was added to only copy files in parallel if the relevant devices are in idle state. This prevents possible fragmentation during copy for HDD drives.

Transferring files no longer steals the current focus.

The file transfer question dialog now provides the same options while having less buttons. In addition, file thumbnails now are properly requested by the dialog.

Launchers

By default, launcher names instead of filenames are shown now for trusted launchers.

Undo/Redo

The user now will be asked before any deletion will be done by an undo operation.

List View

Similar to the tree-view side pane, the main view now also supports folder expansion.

Split View

A shortcut now can be used to toggle between split-view panes, and the focused pane now uses different coloring.

A dialog will now ask for confirmation when closing a split-pane with multiple tabs.

xfce4-appfinder

The application list now as well can be navigated via Ctrl+N / Ctrl+P keys (VI default).

An option was added to close the Appfinder window automatically when focus is lost.

Ctrl+Enter can be used to execute commands immediately when selecting entries from the dropdown.

Within the new version, application specific actions will show on right click.

An option to show generic names of launchers was added.

Appfinder optionally can now be launched as a daemon, so that it will respond even quicker.

An option allows now to launch items on a single click.

xfce4-panel

General

The border width of the panel is now configurable.

For manual installations: the panel now does its best to find plugins in XDG base directories, and better preserves its configuration when it can’t find them.

Clock

LCD clock: An option was added to visualize inactive segments.

Analog: There is now an optional 24h mode.

Digital: Week numbers now are shown optionally.

Show Desktop

There is now the possibility to show the desktop when hovering the mouse on the “show desktop” panel icon.

Tasklist

Icon size management has been improved overall, notably by switching to libxfce4windowing.

Preferences

The ‘delete’ key can now be used to remove panel objects, and several objects can be removed at once.

Panel objects in the panel configuration list now will have the same icons as in the panel itself.

xfce4-power-manager

Screen Locking

There is no dedicated “security” tab anymore. Lock screen management was massively simplified and “Light Locker” was dropped. “lock-on-sleep” is now synchronized with xfce4-session and xfce4-screensaver.

Screen locking settings are now only handled by xfce4-screensaver to avoid conflicts. A button to open xfce4-screensaver-preferences was added:

Power Settings

Support for handling different power profiles via power-profiles-daemon was added.

The overall charge state calculation was wrong for some cases and is now fixed.

When the critical power dialog pops up, unintentional user actions are now prevented.

There is now support for the hybrid sleep mode.

The device details tab now as well shows the energy rate.

Others

Several use-cases for lid close were fixed.

There are now the options “shutdown” and “do nothing” on lid close.

Buttons to change the brightness exponentially and keyboard backlight toggle keys now are supported.

xfce4-session

The logout dialog will not provide a checkbox to enable session saving anymore.

It is now possible to start a Wayland session via startxfce4 --wayland.

Minimal support for xdg-desktop-portal was added by registering for a wallpaper, screenshot and background xapp.

xfce4-settings

Nastavení vzhledu

Icon themes are now loaded in a separate thread, in order to prevent a possible freeze.

For icon themes which are known to be incomplete, a warning now will be shown.

The usage of client side decorations is opt-in now, not opt-out.

Dark themes now are identified and supported in a more reliable way. (Relevant e.g. for the Qogir and Orchis themes)

Nastavení displeje

The default display profile has been added to the list of profiles that can match, and will be used if more than one matches now.

Profile management has been extended to all profiles, not just those that match, and their names can now be edited.

Scaling now always is done for both dimensions, and the preview shows the resulting size.

Mirror state management has been improved overall, in particular by removing the need to match refresh rates.

The minimal dialog has been improved, in particular by allowing the display to be extended to the left and from top to bottom, and with compact profile display.

Mouse Settings

A checkbox was added to toggle between adaptive and flat mouse accel profile.

High resolution scrolling can now be enabled for mice which do support it.

Mime Settings

It is now possible to select/change multiple items at once.

xfconf

A systemd user unit, corresponding to the D-Bus session service, is now added.

Whitespaces are now properly escaped when writing a xfconf channel to disk.

Xfconf-query now displays array contents.

xfdesktop

Background Management

For random wallpaper cycling, wallpapers now are only repeated after all other wallpapers were shown.

Old Xfce backgrounds were ported from .png to .svg to be usable for large screens.

Gradients will now be rendered in a gamma-correct way.

Icon grid

The confirmation dialog for arranging desktop icons now is optional.

It is now possible to set custom colors for icon labels and icon background.

The icon grid on each monitor is now independent of one another.

Minimized Application Icons

Window icons are now initially shown on the monitor where the window was present before being minimized.

The context menu (when clicking on an empty space) now has more useful options than before.

File Icons

There is now an option to sort folders before files.

The positions of the icons are now saved in a way that should avoid icons moving around in unexpected ways when monitors are added and removed.

New files and dropped files now will be placed near the current cursor location.

Icons of fixed disks and drives can now be optionally shown.

Preferences

The ‘Desktop Icons’ tab was fully reworked.

All shortcuts of Xfdesktop now can be configured, using the XfceShortcutsManagers widget.

More folders that hold background images were added as shortcuts in the settings dialog.

The settings dialog will update if the background is changed from outside the dialog.

Wallpaper image folders now are loaded fully asynchronously to prevent lag.

Context Menu

Cascading custom actions will now as well shown correctly in Xfdesktop.

It is now possible to open multiple selected folders at once.

The context menu now opens on button press rather than button release, as most users will expect.

The middle-click window list menu has new styling and added features.

xfwm4

Support for stretch theme variants

Compositor: Block softpipe for GLX vsync

Focus: Include skip taskbar/pager when passing focus

Fix crash when alt-tabbing (#762)
