Linux Mint 22.3, codenamed Zena, is now available to download as a beta release, and Mint is being very open about what that means. This is a long term support version planned to run through April 2029, but this build is still a testing milestone, not the final word. It is meant for evaluation, feedback, and cautious installs, not blind production rollouts.
The beta is based on Ubuntu 24.04 and ships with Linux kernel 6.14. That newer kernel exists mainly to support newer AMD hardware, but Mint is already flagging issues. VirtualBox users may run into problems, and older NVIDIA cards that depend on the legacy 470 driver are likely to break. Since NVIDIA no longer supports that driver on newer kernels, Mint suggests a conservative path: install Linux Mint 22.1 with kernel 6.8 and upgrade forward later without switching to the HWE kernel.
Shutdown behavior has also changed in this beta. The default timeout is now ten seconds, which makes shutdowns quicker but may interrupt long running tasks. Mint explains how to override this if needed, which feels very on brand for a distro that values control over surprises.
VirtualBox testing needs extra care. Mint recommends using the VMSVGA graphics controller, setting video memory to 128MB, disabling 3D acceleration, and enabling Nested Paging. Skipping these steps can lead to black screens or visual glitches. Guest Additions are still required for proper display scaling and shared folders.
There is also a known issue tied to multimedia codecs. Installing mint-meta-codecs pulls in gstreamer1.0-vaapi, which can crash Xorg in virtual machines without 3D acceleration. Enabling acceleration can help, but it may introduce other rendering issues. Mint notes that removing the vaapi package is often the simplest workaround.
Visually, the beta introduces slimmer Ubuntu fonts by default. Audio has fully moved to Pipewire, which should be fine for most users, but Mint acknowledges that sound issues can occur and documents how to revert to PulseAudio if needed. On HiDPI systems, the grub menu may appear too small unless an alternate theme is installed.
Some broader decisions remain unchanged in the beta. The Snap Store stays disabled. ZFS has been removed from the installer. Encrypted home directories still suffer from systemd related regressions. Guest sessions exist but are disabled by default.
Mint also includes a familiar set of practical tips. The live session user is mint with no password. Oversized windows can be dragged by holding Alt. Boot freezes can often be worked around using Compatibility Mode or kernel parameters like nomodeset, followed by installing proprietary NVIDIA drivers.
As a beta, Linux Mint 22.3 Zena is less about polish and more about setting expectations. Mint is clearly signaling what works, what is risky, and where testers should tread carefully. For anyone curious about the next Mint LTS, this beta is informative. Just do not treat it like a finished product yet.
