3.24 differences and known issues in Gentoo
The following is Gentoo specific notes for 3.24 release:
- We have kept the change to defaulting back to Xorg sessions, even if
USE="wayland"is enabled globally. You can still review the available sessions and choose the "GNOME on Wayland" session if you want. We will default to Wayland sessions in GNOME 3.26, if
USE="wayland"is likely to get enabled by default as well in gnome profiles before 3.26 is stabilized.
- There are still some known issues with automatic launch of some background services, such as vino screen sharing and rygel media sharing.
- We may have a different set of applications that are pulled in via our meta-packages. Most applications are packaged, however, and can be installed separately if desired.
