However, the Wayland session option will be available on the login screen for those Ubuntu users who insist on using it.

The updated gdm3 package (version 42.0-1ubuntu7) was uploaded on Thursday and is not included in the Ubuntu 22.04 LTS release image. So all NVIDIA-only systems will receive the updated version of the DGM package as part of their regular updates. If you’re wondering what’s causing this, it’s a last-minute bug, rendering the incorrect frame, which appears visually as a doubling of moving objects or high-frequency judder.Īs a result, the GNOME Display Manager (GDM) package in Ubuntu 22.04 has been updated so that NVIDIA-only systems now use the GNOME X.Org session by default. Unfortunately, a few days ago, just after the official announcement of Ubuntu 22.04, NVIDIA requested Canonical to bring back X.Org as the default GNOME session in Ubuntu 22.04 LTS when using their proprietary driver. To clarify, Generic Buffer Management (GBM) is an API that provides a mechanism for allocating buffers for graphics rendering tied to Mesa. The primary and admittedly sensible argument for this decision is that the latest versions of the NVIDIA proprietary driver support GBM, which puts it in a great position to work seamlessly with Wayland. However, in the last month, Canonical decided that the GNOME session should default to Wayland in Ubuntu 22.04 when using the NVIDIA proprietary driver. At the same time, with NVDIA’s drivers, the default session stuck to X.Org. We’ll briefly clarify that Ubuntu defaulted to using a GNOME Wayland session in recent years rather than X.Org when using Intel and Radeon drivers.

It has to do with NVIDIA and, more precisely, with their proprietary driver when used in the last LTS release of the distro.

And here, just a few days after its release, came some surprising news. NVIDIA requests Canonical to bring back X.Org as default in Ubuntu 22.04 LTS when using their proprietary driver.Īs you already know, Ubuntu 22.04 LTS “Jammy Jellyfish” came out very recently, causing a stir among the Linux community.
