配置ubuntu12.04 AMD64位虚拟机

gparted 分区，删掉分区1，结果归并分区2和分区1的时候，分区2的东西移动到分区1所在的空间，结果这个过程失败了。

只好删掉。我那80G的虚拟机啊，还有积攒了那么久的资料。

以后一定要备份好。

===============================

重新安装了amd64的ubuntu12.-0402，这样就和我电脑上的64位ubuntu12.04系统一样了。

================================= =================================

启用gnome 3 ，

apt-get install gnome-session-fallback

==================================================================
