Dell Precision 7740 with SLED 15.2. Fresh install, I can see the built-in display and three monitors connected to the WD19DC docking station. After installing updates, I only see the built-in display. xrandr --listproviders only shows one provider (before updates it showed two). Any suggestions to get the NVidia and docking station working again?
@Bobby Hi and welcome to the Forum 
I guess this system has the Quadra RTX mobile GPU… Is the SLE-15-SP2-Desktop-NVIDIA-Driver repository enabled for the G05 (450.80.02) driver to support this card?
YaST Package Manager shows two SLE-15-SP2-Desktop-NVIDIA-Driver repositories and the nvidia-computeG05, nvidia-gfx05-kmp-default, nvidia-glG05 and x11-video-nvidiaG05 drivers installed.
Running zypper se x11-video-nvidiaG0* shows the G05 package is installed.
hwinfo --gfxcard | grep Model shows both nVidia and Intel cards. The NVIDIA X Server application will not launch.
xrandr --listmonitors only shows one monitor “0: +XWAYLAND0…”
I have reinstalled using different desktops with the same experience, everything works until I install all updates and then it breaks.
@Bobby Hi, can you log out and switch to X11 rather than Wayland? I would also edit /etc/gdm/custom.conf and unrem the line to set wayland to false. Then look at installing suse-prime to switch igpu/dgpu;

On my desktop I use offloading instead to utilize the nvidia gpu.
Malcom, you are my hero!
Switched to X11, disabled Wayland in the /etc/gdm/custom.conf file rebooted then ran prime-select nvidia.
Logged out, and upon logging back in, all my screens are working!!!
suse-prime was already installed with the Nvidia drivers.
We use SLES for a few applications and I wanted to learn it, so we purchased SLED. Not being able to use all my monitors was depressing but I am so happy now. I cannot thank you enough!
