Hi all! NVIDIA has released today a public BETA test of their proprietary driver which supports hardware acceleration with Xwayland. For this to work, it requires changes and fixes in Xwayland which are already part of the current builds shipped with Fedora 34 (currently in testing is xorg-x11-server-Xwayland-21.1.1-3.fc34). Please help us test this support for hardware acceleration with the NVIDIA proprietary driver in Xwayland, and report issues for Xwayland in Fedora bugzilla (https://bugzilla.redhat.com/enter_bug.cgi?product=Fedora) against xorg-x11-server-Xwayland. By default, the display manager (GDM) will automatically disable Wayland when the NVIDIA driver is loaded. To enable Wayland with NVIDIA's proprietary driver, you'll need comment out that line in the file “/usr/lib/udev/rules.d/61-gdm.rules”: # disable Wayland when using the proprietary nvidia driver # DRIVER=="nvidia", RUN+="/usr/libexec/gdm-runtime-config set daemon WaylandEnable false" And restart your system. This is beta version of the driver, so issues are to be expected and reported: * To the NVIDIA forums for specific NVIDIA driver issues * To Fedora bugzilla for the rest. There is a number of currently known issues: * A blank window with Chromium based web browsers (including GOOGLE Chrome) This is an issue with Chromium's GPU sandboxing, a workaround is to disable GPU rendering with “--disable-gpu” * Applications such as Blender or Steam sometimes show a black window This is an issue with the driver which should be addressed later. * EGL on Xwayland does not work with NVIDIA proprietary driver This is a known limitation in the driver which should be addressed later. * vulkan application such as “vulkaninfo” crashes * GTK3 applications running on Xwayland (GDK_BACKEND=x11 …) fail This is an issue with the driver which falsely claims support for the GLX_EXT_texture_from_pixmap extension, should be addressed later. * GTK4 application show nothing on Wayland with NVIDIA proprietary driver This is a known issue with GTK4 reported upstream here: https://gitlab.gnome.org/GNOME/gtk/-/issues/3772 * Firefox Webrender fails to render on Wayland native with NVIDIA driver Webrender with hardware acceleration uses EGL and fails to render on Wayland with the NVIDIA proprietary driver because of an ambiguity in the EGL specification causing a difference between Mesa and NVIDIA implementations and Firefox Webrender relies on Mesa's implementation. The latest Firefox update for Fedora disables hardware rendering with NVIDIA proprietary driver to work around the issue. * Fullscreen GLX applications do not render in KDE with Xwayland This is an issue with KDE's Wayland compositor. * Shaped windows on Xwayland are upside-down in GNOME Shell This is an issue with mutter reported here: https://gitlab.gnome.org/GNOME/mutter/-/issues/1792 Thank you!
