I installed the beta drivers with “Nvidia GPU Only” enabled in the BIOS. The update caused the UI to crash (wrong resolution, no taskbar), and subsequent restarts result in a black screen. The OS appears to boot successfully in the background (Bluetooth devices still connect).
Switching the BIOS to “Nvidia Advanced Optimus” fixes the issue. I successfully re-ran the driver installer in this mode, but switching back to “Nvidia GPU Only” immediately returns to the black screen. Any suggestions on getting “GPU Only” mode working?
