I need to use x11vnc to access the GDM login screen. In CentOS 9 I could just uncomment the line WaylandEnable=false in /etc/gdm/custom.conf, reboot and it was good to go; GDM then used Xorg. In CentOS 10 this no longer seems to work and GDM still uses Wayland.
How can I disable Wayland and force GDM to use Xorg in CentOS 10?
Xorg was removed from EL 10.
It looks like there are other Wayland-compatible VNC servers / clients available.
Have a look at GNOME / gnome-remote-desktop · GitLab which supports VNC and RDP, but multi-user remote login via GDM via RDP only.
Thanks. It seems that Gnome Remote Desktop is standard in a GUI install of CentOS 10, which is good. However there seem to be some issues with that (I will post about that separately).
