Dual Display not working - Manjaro KDE

Hi there

I registered a query on the old forum re my dual display not working in Manjaro, although it worked fine in Mint

The advice then was to wait for new nVIDIA 450xx hybrid drivers

Have just installed and rebooted and confirmed they are installed via MHWD

Sadly dual monitor still not recognised

Grateful for some pointers please as I miss having this resource in this version of Linux

Cheers

Should add I have a HP Omen Elite Gaming Laptop connected to a Dell Monitor via HDMI through a Toshiba Dynadock 3.0 docking station

Tried following after Googling:
xrandr --output eDP-1 --auto --output HDMI-1 --auto --above eDP-1
xrandr --output HDMI-1 --auto

xrandr has following output that shows my HDMI is disconnected even though it was fine in Mint and still works in Windoze:

video-hybrid-intel-nvidia-450xx-prime 2019.10.25 false PCI

Warning: No installed USB configs!

Could it be to do with the fact that my laptop connects to the dock via a USB 3 connection?

Hello,

Remove video-modesetting and reinstall video-hybrid-intel-nvidia-450xx-prime then reboot.

Thanks for the quick reply. Any chance you could advise re actual scripts so I can paste please

sudo mhwd -r pci video-modesetting
sudo mhwd -f -i pci video-hybrid-intel-nvidia-450xx-prime
systemctl reboot

Thanks on running first command got:
Error: config ‘video-modesetting’ is required by config(s): video-hybrid-intel-nvidia-450xx-prime

I ran both commands, ignoring first error message and rebooted.
Unfortunately did not change anything

Ah, ok. Then i understood it backwards. So, you keep the video-modesetting but remove video-linux and then reinstall the video-hybrid-intel-nvidia-450xx-prime
You should be able to do that even from TTY.

Thanks again for your quick advice
Followed through both commands but regrettably the issue remains
:o(

So, what you did when this was suggested in the archived forum?

Ok will do. The hybrid laptop was identified previously in July when I had 440 driver. i was told the 450 would resolve. So do I try optimus now?
