SUSE 15 SP3 Desktop Modules Not Loading - GNOME Session and Xorg Issues

I have been experiencing issues with the GNOME desktop environment on my SUSE 15 SP3 server with desktop modules. The GNOME session fails to start, and the Xorg configuration seems to be problematic. Below are the details of the errors and steps I have taken so far:

Error Messages:

  1. Polkit and D-Bus Errors:
  • Unregistered Authentication Agent for unix-session:c1 (system bus name :1.71, object path /org/freedesktop/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8) (disconnected from bus)
  • Failed to grab accelerators: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying
  1. GNOME Shell and X11 Errors:
  • gnome-shell-x11.service: Main process exited, code=killed, status=4/ILL
  • gnome-shell-x11.service: Failed with result 'signal'
  • gnome-shell-x11.service: Start request repeated too quickly
  • Dependency failed for GNOME Shell on X11
  • Dependency failed for GNOME X11 Session
  1. Xorg Configuration Issues:
  • Cannot establish any listening sockets - Make sure an X server isn't already running
  • Screen 0 deleted because of no matching config section
  • Unable to find a valid framebuffer device
  • open /dev/dri/card0: No such file or directory

Steps Taken:

  1. Verified and reinstalled GNOME packages:
sudo zypper verify
sudo zypper install -f gnome-session gnome-shell
  1. Checked and reconfigured Xorg:
sudo Xorg -configure
sudo mv /root/xorg.conf.new /etc/X11/xorg.conf
  1. Disabled GNOME Shell extensions:
gnome-extensions disable [extension-name]
  1. Reinstalled graphics drivers:
sudo zypper install -f xorg-x11-driver-video
  1. Reviewed systemd journal logs:
sudo journalctl -xe
sudo journalctl -u display-manager
  1. Ensured Polkit and D-Bus services are running:
sudo systemctl status polkit
sudo systemctl restart polkit
sudo systemctl status dbus
sudo systemctl restart dbus

Despite these efforts, the issue persists. I am seeking assistance from the community to resolve this problem. Any insights or suggestions would be greatly appreciated.
