.Limitations of the *Wayland* session With Red Hat Enterprise Linux 8, the GNOME environment and the GNOME Display Manager (GDM) use *Wayland* as the default session type instead of the *X11* session, which was used with the previous major version of RHEL. The following features are currently unavailable or do not work as expected under *Wayland*: * *X11* configuration utilities, such as `xrandr`, do not work under *Wayland* due to its different approach to handling, resolutions, rotations, and layout. You can configure the display features using GNOME settings. * Screen recording and remote desktop require applications to support the portal API on *Wayland*. Certain legacy applications do not support the portal API. * Pointer accessibility is not available on *Wayland*. * No clipboard manager is available. * GNOME Shell on *Wayland* ignores keyboard grabs issued by most legacy *X11* applications. You can enable an *X11* application to issue keyboard grabs using the `/org/gnome/mutter/wayland/xwayland-grab-access-rules` GSettings key. By default, GNOME Shell on *Wayland* enables the following applications to issue keyboard grabs: ** *GNOME Boxes* ** *Vinagre* ** *Xephyr* ** `virt-manager`, `virt-viewer`, and `remote-viewer` ** `vncviewer` * *Wayland* inside guest virtual machines (VMs) has stability and performance problems. RHEL automatically falls back to the *X11* session when running in a VM. If you upgrade to RHEL 8 from a RHEL 7 system where you used the *X11* GNOME session, your system continues to use *X11*. The system also automatically falls back to *X11* when the following graphics drivers are in use: * The proprietary NVIDIA driver * The `cirrus` driver * The `mga` driver * The `aspeed` driver You can disable the use of *Wayland* manually: * To disable *Wayland* in GDM, set the `WaylandEnable=false` option in the `/etc/gdm/custom.conf` file. * To disable *Wayland* in the GNOME session, select the legacy *X11* option by using the cogwheel menu on the login screen after entering your login name.
