How to save settings on second screen

Hi I'ma new to Manjaro.

I would like to ask how to save the settings on second screen (connected by HDMI).

It is originally copy of the first screen, but I would like to make the second monitor "right of" the origin screen.

I tried "nvidia-settings", but once unplugged and plugged, it would return to copy of the first screen. (But will keep after reboot.......)

I'm using "Lxrandr" and "nvidia-prime" driver.

Thanks a lot!

:+1:Welcome to Manjaro!:+1:

Please read this:

and post some more information so we can see what's really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies...

:wink: :+1: :innocent:

P.S. If you enter a bit more details in your profile, we can also see which Desktop Environment you're using, which CPU/GPU you have, ...

If you run "Display" you should be able to set where the monitors are in regards to each other. I have a 3 monitor layout, but I keep them all plugged in, so I'm not sure if the settings are saved when they are disconnected/reconnected.

Hi really thanks for the replay and sorry for missing important information.

Basic info here:

System: Manjaro 18.1.5
Desktop: Xfce
GPU: Nvidia GTX 1060 & Intel
Driver: Video-hybrid-intel-nvidia-440xx-prime

I followed this link to configure the driver.

Sorry for the late reply, any info I missed, please let me know. Thanks!!!

I know that the hybrid drivers have some issues in multi-monitor mode.

  1. Have you tried with nVidia only?
  2. Have you tried the hardware switch on your laptop? (I don't have an Alienware, please refer to the manufacturer's hardware manual)


That alters your /etc/X11/xorg.conf settings and so overrides any DE settings and display autodetection.

If you want to dynamically reconfigure your displays then stick to the DE's display configuration (which should be using xrandr as its backend).

You'll likely have to remove the xorg.conf you created in order to use X's display autodetection.

Thanks again for the replay and sorry for my late response (due to busy work......)

I followed the tutorial and I believe the tutorial made nvidia as the graphic hardware:

[shore@shore-pc ~]$ glxinfo | grep -i vendor
server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation

And hardware switch, I do not really know what is it......

Probably due to I'm new, I may need some more instruction for that ..........

Hi, thanks for the reply.

I tried to remove the files, it will keep settings after plug and unplug.

However, after reboot, it will back to copy screen......

So using nvidia setting will reset the setting after replug-in, not using it will reset after reboot T T

There is no hardware switch: just a software one.

To remove the hybrid driver:

  1. Print off these instructions

  2. Reboot

  3. Do not log on!

  4. Before you do the next step, remember that Ctrl+Alt+F1 is your friend! (to switch back to the GUI and why you needed to print off these instructions)

  5. switch to tty2 by pressing Ctrl+Alt+F2

  6. Log on

  7. Execute this command to remove the hybrid driver:

    mhwd --remove pci video-hybrid-intel-nvidia-440xx-prime
  8. Install the nVidia proprietary driver

    mhwd --install pci video-nvidia-440xx
  9. sudo reboot

  10. Done!

Thanks a lot. I'll try later in this weekend~~~ lol

Thx lol. Worked :grinning:
