If you still have the video-nvidia-450xx installed, what does xrandr print?

I see thanks for catching that…I changed my config but the results were the same (blank screen on my laptop & no output on the monitor)

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "intel"
    Inactive "nvidia"
    Option "AllowNVIDIAGPUScreens"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1:0:0"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
EndSection

Section "Device"
    Identifier "intel"
    Driver "modesetting"
    BusID "PCI:2:0:0"
EndSection

Section "Screen"
    Identifier "intel"
    Device "intel"
EndSection

I got the bus-id from inxi --full -verbosity=7 (hope that is right)

Device-1: Intel HD Graphics 630 vendor: Dell driver: i915 v: kernel bus ID: 00:02.0 chip ID: 8086:591b

Sorry I switched to prime so I don’t have video-nvidia-450xx installed. I also don’t seem to have xrandr installed…

24

This should be BusID "PCI:0:2:0".

25

Then install it: sudo pacman -Syu xorg-xrandr.

I see, thank you for correcting the busID

But this gave me the same result (blank screen)

So you didn’t get any signal anywhere? Neither on monitor nor on laptop screen?
(Also: the 450 series is pretty new and still has some issues and why I asked you to install the 440 series as your GTX 1050 is supported by that one)

:man_shrugging:

Can you get the Xorg logs? Log into a tty, and then run startx -- -logverbose 10, and if it fails, check the files in ~/.local/share/xorg/.

I am starting to think that something is wrong at a basic level…because when I boot into windows 10, I can’t even mirror my display there…

30

Sure I will try that today after work, and update you guys - thank you for the follow up.

Smells like a hardware error…

Hello, I’ve tried several possible solutions for this same problem, that’s how I got here, reverse prime didn’t work out, nor going full nvidia. The only solution that worked for me, was to install optimus-manager, Guide: Install and configure optimus-manager for hybrid GPU setups (Intel/NVIDIA) - Tutorials - Manjaro Linux Forum. (itś kinda outdated, stiil worked though)because i have a hybrid amd-nvidia, I decided to install it from source. It’s been a couple of days and so far it’s working ok, you can leave it full nvidia, full integrated, or hybrid and switch between them just login out , in hybrid running programs with prime-run works as well. Hope this helps,
