I've created a minimal machine with no graphics using virtualBox, For I want to use a pure command line environment. One thing I don't like about it is, that it shows up in half screen. There's an option in VirtualBox to zoom display but it somehow pixelates the display.



I know there is a way to increase the default font by customizing the bash files in user's home directory. But nonetheless it will still show in half screen.



I want to know if anyone of you know how to change default resolution of a CLI machine in VirtualBox. I'd really be grateful.



(Note: Someone suggested to edit /etc/default/grub file for Ubuntu, but I can't happen to find it in Centos)

  • There's no much sense in optimizing screen for VM w/o graphics You can run it in headless mode and use ssh to connect to it with your favorite terminal program from your host machine where you have control over the screen.

A maximum resolution of 800x600 suggests that your X server inside the virtual machine is using the SVGA driver. SVGA is the highest resolution for which there is standard support; beyond that, you need a driver.



VirtualBox emulates a graphics adapter that is specific to VirtualBox, it does not emulate a previously existing hardware component like most other subsystems. The guest additions include a driver for that adapter. Insert the guest additions CD from the VirtualBox device menu, then run the installation program. Log out, restart the X server (send Ctrl+Alt+Backspace from the VirtualBox menu), and you should have a screen resolution that matches your VirtualBox window. If you find that you still need manual tweaking of your xorg.conf, the manual has some pointers.



There's a limit to how high you can get, due to the amount of memory you've allocated to the graphics adapter in the VirtualBox configuration. 8MB will give you up to 1600x1200 in 32 colors. Going beyond that is mostly useful if you use 3D.
