Lubuntu previously used the PulseAudio audio system to provide rich audio functionality to our users. However, recently Ubuntu and its flavors have been gradually shifting to using the PipeWire audio server in place of PulseAudio. PipeWire offers several advantages over PulseAudio, including improved Bluetooth support, and more powerful management features for complex audio-related workloads. In order to offer these improved features to our users, Lubuntu has replaced the PulseAudio audio system with PipeWire in Lubuntu 23.04. Since Lubuntu 20.04, the default screensaver has been 'Flurry'. Due to reports of screensaver glitches on certain hardware, we have switched the default screensaver in Lubuntu to GL Matrix. This screensaver features a 3D “digital rain” effect that we have found to be aesthetically pleasing. If you have changed the screensaver yourself, you will probably not notice this change. If you find the new screensaver unappealing, you can change it back to the original 'Flurry' screensaver (or to any of the other pre-installed screensavers) using the Screensaver application. Lubuntu 22.10 and earlier run with no X compositor by default. (An X compositor is an application that can help provide various graphical effects and possibly smooth out screen tearing.) For those who benefited from X compositing, the Compton compositor was provided. We began also providing the Picom compositor (which is based on Compton but is more well-maintained) in Lubuntu 21.04. Starting with Lubuntu 23.04, we have switched entirely to Picom, and have enabled X compositing by default. This will allow effects like panel transparency to work out of the box rather than requiring that the compositor be manually enabled.
