Black Screen After Logo When Using Optimus (After AMD and NVIDIA Driver Update)

Hi,
I have an Acer laptop with both AMD and NVIDIA GPUs. After updating both the AMD and NVIDIA drivers to the latest versions, my laptop stopped booting properly. It shows the Acer logo, then the screen stays black — no login screen or desktop. However, if I plug in an external monitor via HDMI, everything works fine.

I’ve discovered that the issue only happens when Optimus (hybrid graphics) is enabled. When I change the display mode in BIOS to “NVIDIA GPU only”, the laptop screen works normally again an

This makes me think that the AMD GPU (which is likely responsible for the internal screen in Optimus mode) no longer properly recognizes or controls the display after the driver update.

I would prefer to use Optimus for better battery life, but right now it makes the system unusable unless I use an external display or switch to GPU-only mode.

    It definitely sounds like the AMD driver update broke the internal display handling when running in Optimus mode. This issue happens sometimes when there’s a conflict between the AMD and NVIDIA drivers, especially with newer versions. A good first step would be to try completely uninstalling both GPU drivers using DDU (Display Driver Uninstaller) in safe mode, then reinstall the AMD driver first, followed by the NVIDIA driver, sometimes the order matters. Also, check if Acer has a recommended version of the AMD driver specifically for your model, as OEM-tuned drivers often work better with hybrid setups. Hopefully, this lets you keep using Optimus without issues.”
