Z16 Beta. Dual Monitor Issue

Iam running zorin 16 core on Asus i3 laptop with Intel HD graphics 620

I have a dual monitor (1920x1080) monitor setup.

The issue is that, my secondary monitor (acer monitor) is by default working as primary monitor, though in the display setting, I have setup my laptop monitor as primary but still the secondary monitor is acting as primary.

Anyone facing similar issuescreenshot

I have editited the title to highlight that it refers to new Z16 Core Beta.


In Terminal type:

xrandr -q

This will show you the names of your devices. My output was:

virtdev@VirtDevTuf:~$ xrandr -q
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384
eDP connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 382mm x 215mm
   1920x1080    120.00 +  60.00* 
   1680x1050    120.00  
   1280x1024    120.00  
   1440x900     120.00  
   1280x800     120.00  
   1280x720     120.00  
   1024x768     120.00  
   800x600      120.00  
   640x480      120.00  
HDMI-A-0 disconnected (normal left inverted right x axis y axis)
DP-1-0 disconnected (normal left inverted right x axis y axis)
DP-1-1 disconnected (normal left inverted right x axis y axis)

So I have Screen 0 and HDMI-A-0
Now you can set them with:

xrandr --output HDMI-A-0 --auto --left-of Screen 0 --output Screen 0 --auto --primary

change left to right depending on your setup.

I got this xrandr command from:

in the comments of the first answer.

It is odd that the GUI doesn't change the configuration. Something @AZorin will definitely have to take a look at.

I have got screen 0 and HDMI - 1 , when I try to enter the command, get an error message that '0' is not recognised.
Still donot understand why primary screen is acting as secondary. This issue was with me in zorin15 version as well
Any help would be appreciated

Your primary display (internal) is eDP-1... not screen 0... change the Screen 0 to reflect your device name... and use HDMI-1... not HDMI-0... those were my laptops identifiers.

I hope this resolves your issue.

I tired but display is not changed

xrandr --output HDMI-1 --auto --left-of eDP-1 --output eDP-1 --auto --primary

So this is the command you used? With the names changed to reflect your system?

I'm not sure, I'll have to do some more digging. This should have set the internal as primary and external as secondary with extended.

yes, i tried the above command.
Appreciate, if you can help me out :slightly_smiling_face:

Would you be so kind to share what kind of graphics cards you have? If you have nvidia, did you check which driver it's using (software updater -> settings -> last tab on right (forget what it's labeled) )

Is there Radeon or nvidia software in your system category? It may be controlled through that. I know Nvidia is good for doing that kind of thing.

Also, don't think this is part of your issue, but check the bios display settings and make sure integrated is selected, not discrete.

I have got inbuilt Intel HD graphics 620

Try eDP instead of eDP-1 in setting xrandr.

Got this error - "warning: output eDP not found; ignoring"
