How to set up the guest system, so the virtual display are shown as true display?

[Lisa Miller]

My envirement:
Host:
* Debian based OS (LMDE4)
* Virtual Box 6.1.14

Guest:
* Debian based OS (LMDE4)

In guest system i get on the Debian based OS (LMDE4), the display shown as "Virtual Display"
How to configure, the guest system, so the display no more shown as virtual monitor. A display of the monitor as as notebook LVDS display or as external VGA or DVI or HDMI monitor will be great. I prefer the virtual display will be shown as LVDS notebook display.

I have an application software that queries the type of display and if it doesn't recognize an LVDS notebook display or an external display, it refuses to work.

I think there is no built-in way to change the names of the 'hardware' the guest OS sees. You'd have to edit the source code and rebuild Virtualbox.

You'd have to edit the source code and rebuild Virtualbox.

And write new guest OS device drivers for everything.

Hi Lisa,

You may also try changing the Graphics Controller...

VirtualBox Manager > Machine > Settings > Display
1. Uncheck 'Enable 3D Acceleration:'
2. Try VBoxVGA or VBoxSVGA (latter normally used for Windows VMs)

Doing this shows the display as 'VGA-1' instead of 'Virtual...'

Notes:
Display performance will be slower due to software rendering.
'Invalid settings detected' warning can be ignored to test if your software works.
If 'Enable 3D Acceleration' isn't unchecked, display will default back to VMSVGA.

Thx a lot. Thats works fine:
* xrandr report 'VGA-1' and not like before "Virtual1 cnnected" and a list of "Virtual2 to 8 disconnected"
* It looks like the Error message on VirtualBox GUI "non valid configuration found" ( if 1. Uncheck 'Enable 3D Acceleration:' 2. Try VBoxVGA or VBoxSVGA (latter normally used for Windows VMs) can be ignored.

Checked on:
* Virtual Box 6.1.14 r140239 (Qt5.11.3)
* Guest LM20.4, guest add ins 6.1.14 installed

That does not answer the original question. The VM still has a virtual monitor, as it always must, it just so happens that you happened upon a third party tool that does a crappy job of identifying this particular hardware. Who's to say what the next version increment of that tool will show?
