My KWIN fork where I work on features like per-output virtual desktops

Vlad Zahorodnii 0aaa57e18e Assign default name if new virtual desktop has no explicit name
If a virtual desktop has empty name, kwin is going to end up in an
infinite cycle where VirtualDesktopManager::save() updates the
_NET_DESKTOP_NAMES property and then in the next event loop cycle,
RootInfoFilter::filter() is going to call VirtualDesktopManager::save()
because the _NET_DESKTOP_NAMES property has been changed.

This regression has showed up just now because some parts of kwin used
to increase virtual desktop count to create new desktops. Recently, that
code was ported to VirtualDesktopManager::createVirtualDesktop().

The main difference between createVirtualDesktop() and setCount() is
that the latter will set the desktop name to "Desktop N", the former
will use user-specified name.

If the user-specified name is empty, the createVirtualDesktop() method
should assign "Desktop N" name to the virtual desktop according to the
docs. However, it's not the case and this change addresses that.

KWin

KWin is an easy to use, but flexible, composited Window Manager for Xorg windowing systems (Wayland, X11) on Linux. Its primary usage is in conjunction with a Desktop Shell (e.g. KDE Plasma Desktop). KWin is designed to go out of the way; users should not notice that they use a window manager at all. Nevertheless KWin provides a steep learning curve for advanced features, which are available, if they do not conflict with the primary mission. KWin does not have a dedicated targeted user group, but follows the targeted user group of the Desktop Shell using KWin as it's window manager.

KWin is not...

  • a standalone window manager (c.f. openbox, i3) and does not provide any functionality belonging to a Desktop Shell.
  • a replacement for window managers designed for use with a specific Desktop Shell (e.g. GNOME Shell)
  • a minimalistic window manager
  • designed for use without compositing or for X11 network transparency, though both are possible.

Support

Application Developer

If you are an application developer having questions regarding windowing systems (either X11 or Wayland) please do not hesitate to contact us. Preferable through our mailing list. Ideally subscribe to the mailing list, so that your mail doesn't get stuck in the moderation queue.

End user

Please contact the support channels of your Linux distribution for user support. The KWin development team does not provide end user support.

Reporting bugs

Please use KDE's bugtracker and report for product KWin.

Guidelines for new features

A new Feature can only be added to KWin if:

  • it does not violate the primary missions as stated at the start of this document
  • it does not introduce instabilities
  • it is maintained, that is bugs are fixed in a timely manner (second next minor release) if it is not a corner case.
  • it works together with all existing features
  • it supports both single and multi screen (xrandr)
  • it adds a significant advantage
  • it is feature complete, that is supports at least all useful features from competitive implementations
  • it is not a special case for a small user group
  • it does not increase code complexity significantly
  • it does not affect KWin's license (GPLv2+)

All new added features are under probation, that is if any of the non-functional requirements as listed above do not hold true in the next two feature releases, the added feature will be removed again.

The same non functional requirements hold true for any kind of plugins (effects, scripts, etc.). It is suggested to use scripted plugins and distribute them separately.
