Haiku window smaller than the screen


I have a Xiaomi Air 13" running Debian 9.

I have created a VM using the recent release of Haiku from the 21 of August

Haiku boots fine but uses a window centered on the screen, of a size of about 9"

How do I use the whole screen?

Thanks for ant hint

For VirtualBox, you can follow the guide:

VBoxManage setextradata "VM name" "CustomVideoMode1" "1400x1050x16"

I did it but it did not work.

In virtual box
tthe scale factor is at 100%, when I put it at 200%, the haiku window uses all the screen.


You have to enter the shell and execute the above line (with the actual “VM name” you gave your VM and the resolution you aim for, of course).
