In this video I show how to install Oracle VirtualBox Guest Additions and video drivers from a TTY in a Linux VM that won't load a desktop.
NOTES
Increase video memory for VirtualBox VM run in Host terminal:
VBoxManage modifyvm "Name of VM" --vram 256
Install Guest Additions from TTY in VM:
1. Boot VM, switch to TTY with right Ctrl and F2 key.
2. Log in at prompt.
3. Open Devices and select Inerst Guest Additions CD Image.
4. Mount the CD with :
sudo mount /dev/sr0 /mnt
