无法安装成功真强包，无法开启自动调整显示尺寸，64为系统才这样

[xihuan]

下面是 /var/log/vboxadd-install.log文件内容
/tmp/vbox.0/Makefile.include.header:97: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again。 停止。

===============================
应该怎么处理，只在64位系统这样

[xihuan]

解决，原来是安装后还要手动启用驱动，32位系统自动启用

上面的解决方法不对，原因找到，要在软件中心里，装Generic Linux Kernel headers软件包，32位系统似乎不许要，可能自动已经安装
