I have installed and working nvidia-settings and this working good, recognize the graphic card (sorry I can’t put image here)

I test in kubuntu and works perfect but I like Arch distributions such as Manjaro, please, any have some idea how to fix that?

please help me, I need use a propetary drivers to control NVIDIA Graphics and I need an external monitor too. I am new, and I don’t known how to solve, thanks!

I am facing the same issue. Were you able to find a solution?

Hey I got it resolved by switching to nvidia drivers (using optimus-manager-qt). It appears that my laptop (Asus TUF FX505DT) has the hdmi output connected only to the dedicated gfx card so loading the nvidia drivers was necessary. The steps I took are:

  1. install nvidia drivers (pamac install linux511-nvidia)

  2. blacklist nouveou

  3. install optimus-manager-qt (pamac install optimus-manager-qt)

  4. reboot

  5. start optimus-manager-qt from command line

  6. switch to nvidia drivers using the tray applet.


Thank you, it really works.
