virtualbox 安装ubuntu 14.04后分辨率不正确的问题修复
Instead of using the Virtualbox Guest Addition ISO file, try using the following commands in the terminal on the guest Ubuntu Virtual Machine :
Update apt-get. apt-get update
Install dependencies apt-get install build-essential linux-headers-$(uname -r)
Install guest additions apt-get install virtualbox-guest-x11
Use sudo before the commands if required.
