Set it as first item:įinally, restart the display manager and the NoMachine server to make changes effective: Then, modify the 'WaylandModes' key in /usr/NX/etc/node.cfg in order to enable the EGL method. These changes can be applied automatically by running the following command: Such method requires modification of the desktop startup scripts. Since the Wayland desktop is composed by using the EGL library, NoMachine can grab the screen content through EGL. In this way, NoMachine will try PipeWire (compositor) and in case it will fall back to DRM (Direct Rendering Manager) framebuffer. To force using it, set 'compositor' as first method in the 'WaylandModes' key in the NoMachine node configuration file (/usr/NX/etc/node.cfg), for example: NoMachine is able to use PipeWire to get access to the desktop sharing service, where available (only GNOME is currently supported). Option #1: PipeWire desktop sharing provided by the desktop compositor It's possible to change the server-side setup to fix such situation, two alternative ways are available. nxagentShadowInit: ERROR! Failed to initialize the shadow display.

The session log reports errors similar to:Ģ0982 21009 12:22:25 117.174 DrmGrabber: ERROR! Failed to get fb info. The client window is however responsive: open the NoMachine menu by ctrl+alt+0, enter the Display -> Change settings panel and check at the bottom left: it should show ' codec Unknown'. When connecting to the Wayland-based desktop, the user gets a blank screen. A possible solution for both cases is to disable Wayland, or when this is not possible, to try any of the options explained below. Note that even in this case, some issues can still occur when the proprietary drivers of the video card are installed. In case of a Wayland-based desktop, NoMachine adopts a variety of methods to interact with it, but at the moment these methods are effective only when the Operating System is running on a physical host. The same applies to the NoMachine software, that can be installed on a physical or virtual host to provide access to its desktop. These Wayland-based desktops operate also when the Operating System runs on a bare-metal virtual machine or in virtual machine on a hosted hypervisor like VMware Workstation Player, VirtualBox, KVM, VMware ESX. Fedora 31, OpenSUSE 15, Ubuntu 19.10 or later) provide support for desktop environments relying on Wayland compositor. Many recent Linux operating systems (e.g. This article applies to NoMachine v6, v7 and v8.
