Notable changes for desktop users
With this enhancement, Fedora adds
cgroup based resource protections for the active graphical session. For this, the system performs the following steps:
Passes a memory protection of 250MiB to the active users, that is limited at 10% of system memory.
Enables other cgroup controllers such as CPU, IO, between others.
This ensures that important session processes get the required resources. As a result, it improves interactivity of graphical sessions in certain situations. It also takes advantage of the benefits of
cgroups in workstation scenarios.
Starting with Fedora 33, the
earlyoom service is enabled by default when using the KDE desktop environment. See the Distribution-wide Changes section for details.
The default partitioning scheme on Fedora Workstation now uses Btrfs. See Distribution-wide Changes for more information.
