I've researched some for an answer to what seems a common question but I still need more help. I am a complete newbie.
I installed ubuntu 12.04.5 LTS on Oracle Virtualbox 64bit set up for ubuntu.
The only thing I've done on top of the default install is install the lsb_core. sudo apt_get install lsb-core
I was working through a tutorial that told me to try this: xload to which I get this: Error: Can't open display:
When I type echo $DISPLAY, all that is returned is a completely empty row. Most of my googling brought me to issues where the wrong value was displayed, not nothing.
I'm assuming I need to install some sort of graphical package. If that is correct I'm not sure how to select the correct one.
This is what the virtual box documentation says about the graphical device: The VirtualBox graphics device (sometimes referred to as VGA device) is, unlike nearly all other emulated devices, not based on any physical counterpart. It is a simple, synthetic device which provides compatibility with standard VGA and several extended registers used by the VESA BIOS Extensions (VBE).
