VirtualBox linux development virtual environment to build a pit (3) screen size setting

The default screen size of VB is 800*600 . After installing Addtions , it will become 1024*768 , and then it is still too small. 24 -inch monitors are all 1920*1200 , which cannot be used when writing code in full screen.

Need to add monitor information to /etc/X11/xorg.conf

vi /etc/X11/xorg.conf

The content is as follows

Section "Device"

        BoardName    "VirtualBox Graphics"

        Driver       "vboxvideo"

        Identifier   "Device[0]"

        VendorName   "Oracle Corporation"

Section "Screen"

  SubSection "Display"

  EndSubSection

  Device       "Device[0]"

  Identifier   "Screen[0]"

  Monitor      "Monitor[0]"

EndSection
