When I switch to Nvidia, the built-in screen of the laptop stays black but I can still input my password or use monitors plugged to a video output #552

Describe the bug I'm having a problem described in the trouble shooting section of the wiki: "When I switch to Nvidia, the built-in screen of the laptop stays black but I can still input my password or use monitors plugged to a video output".

When I switch to Nvidia (or simply boot in Nvidia mode), my Display Manager won't show up: my laptop screen is black. I can enter my password, then my Window Manager starts and finally the screen is working as expected. Therefore the black screen only happens on the log-in screen from my Display Manager.

Other modes (integrated, hybrid) don't have any problem.

The wiki suggests that this may be a Prime configuration problem. All my packages are up to date. Any help would be greatly appreciated.

Any help is appreciated, thanks!

After further tests, it appears that my laptop screen is NOT powered at all on my login screen. So it's not a black screen, rather a disabled/turned off screen.

Hello @T-3B .

How is Prime configured at the firmware(BIOS) level here? I had the very same issue on my Asus TUF if I set my laptop to the "Ultimate" mode. Completely black screen until having a full Xorg session.

Also, have you tried optimus-manager-git recently?

@nwildner Thank you for your message!

In my BIOS (which I enter with the F12 key at startup), there very limited options (only SATA/NVMe and boot configurations are available). So I cannot do anything on this side for changing the "Ultimate" mode (except if I should change the BIOS but I never heard anything like that).

I just tried optimus-manager-git, and... it is even worse: after changing to nvidia mode, my screen is still turned off (even after entering my password). I know I managed to still unlock my login manager (and entering my WM) because I did some actions blindly that I could find in the future with integrated (or hybrid) mode.
