\"\"<\/a><\/p>\n

GNOME 49, the default desktop environment for next Ubuntu 25.10 and Fedora Workstation 43, is available for Beta testing.<\/p>\n

This Beta is available more than a month after the first Alpha. There will also be a RC release, while, the final of GNOME 49 is planned for September 17<\/b>.<\/p>\n

<\/p>\n

In last Alpha<\/b>, the desktop added support relative dials on tablet pads<\/i>, disabled Xorg<\/i> session, and introduced new Glycin loader<\/i> as backend library for gdk-pixbuf and loupe image viewer.<\/p>\n

It as well moved “Do Not Distrub” to top-right quick settings menu, added configuration for trackpoint, and touch support in Gnome Remote Desktop.<\/p>\n

In this Beta<\/b>, it updated GDM to enable systemd-based session management on the greeter and dropped the builtin service manager code.<\/p>\n

For music players that are well integrated with GNOME, the media playback control will now even appear on the lock screen.<\/p>\n

It also added an option to show “Restart” and “Power-Off” menu options to the lock screen.<\/p>\n

This however is NOT enabled by default. If you want, either install & open “Dconf Editor” and configure it by navigating to “org.gnome.desktop.screensaver<\/code>“, or run command below in a terminal to enable:<\/p>\n

gsettings set org.gnome.desktop.screensaver restart-enabled true<\/pre>\n

PowerOff, Reboot from Lock screen (Not enabled by default)<\/p><\/div>\n
For computers with multiple monitors<\/b> connected, the release added per-monitor brightness control in top-right Quick Settings menu.<\/p>\n
The feature however does NOT work in my case, when trying Ubuntu 25.10 snapshot in my laptop with an external monitor connected, though ddcutil<\/a> works.<\/p>\n

GNOME 49 Beta as well improved the Glycin loader<\/i> image loading backend. It added support saving JXL images, and CICP support for HEIC and AVIF for specifying the color space of image\/video data.<\/p>\n
And, it added a “Donate” button in the about system page, which will open donate.gnome.org<\/a> page in browser, with options to support GNOME by one-time or monthly donation.<\/p>\n
