VirtualBox in Ubuntu 14.04 screen resolution cannot set the issue

?? Ubuntu 14.04 Sets the screen resolution in the VirtualBox virtual machine, and it doesn't respond at all.

sudo apt-get install virtualbox-guest-dkms

sudo apt-get remove libcheese-gtk23sudo apt-get install xserver-xorg-coresudo apt-get install -f virtualbox-guest-x11

如果还不行，那就用下面这个方法：
方法二：我忘了修改哪个文件了，好像是grub，哪天想起再来补上，修改默认分辨率800*600那个，重启虚拟机就可以了。记得要重启virtualbox啊。。
