debain(wheezy) 安装增强功能提示无权限解决方法

在虚拟机里面安装debian来gnome3,默认要按照增强公司才能使用gnome3,按照增强功能提示一下错误.

root@debian:/media/cdrom0#
./VBoxLinuxAdditions.run

bash: ./VBoxLinuxAdditions.run:
Permission denied

解决

root@debian:/media/cdrom0# mkdir /media/vboxguest
root@debian:/media/cdrom0# mount -r /dev/cdrom /media/vboxguest/
root@debian:/media/cdrom0# ls /usr/src/|grep ker
root@debian:/media/cdrom0# cd /media/vboxguest/
root@debian:/media/vboxguest# ls

搞定安装完毕,若安装过程中提示错误请先执行:apt-get install build-essential
linux-headers-`uname -r`

NOTE:关闭虚拟机,设置打开此虚拟机的3d加速功能,重新运行虚拟机后,登陆的时候选择gnome登陆,非系"system default"或者"gnome classic"
