Vmware安装ubuntu64报错及黑屏

问题一描述：Vmware安装ubuntu64系统，按步骤完成配置开始安装时提示：

You have configured this virtual machine to use a 64-bit guest operating system.  However, 64-bit operation is not possible. This host is VT-capable, but VT is disabled.
This is usually because VT has been disabled in the BIOS/firmware settings or the host has not been power-cycled since changing this setting. Please:
(1) Verify that the BIOS/firmware settings enable VT and disable ‘trusted execution.’
(2) Power-cycle the host, if either of these BIOS/firmware settings have been changed.
(3) Power-cycle the host, if you have not done so since installing VMware Workstation.
(4) Update the host’s BIOS/firmware to the latest version.
For more detailed information, see http://vmware.com/info?id=152.
Continue without 64-bit support?

问题解决，重启电脑进入BIOS环境，在config-CPU标签页中看到一行英文提示：虚拟化技术disable，回车后有两个选项，选择enable后保存退出，启动电脑后可以正常安装。

问题二描述：Vmware成功安装ubuntu64系统，安装成功后开启虚拟机输入密码后一直黑屏。
开始以为是安装有问题，重新安装后依然这样，后来又想是不是安装版本的问题，尝试了所有版本都出现相同的情况。最后看了网友们的讨论才知道是因为在默认设置中显示器开启了加速3D图形，所以才会显示黑屏。
问题解决，进入虚拟机的设置选项-》点击显示器-》关闭加速3D图形，应该可以正常显示。
