我已通过升级先前版本 12.10 成功从实时 USB 安装了 Ubuntu 13.04。我使用 Windows 双启动 Ubuntu。
安装 Linux Image 3.8.0.19 后。三十_i386.deb 我只在第一次就成功重启了计算机。
然而，下次重新启动时出现启动问题，因为它没有自动启动到 Ubuntu 13.04。
现在它显示一条错误消息，提示 KVM 已被 BIOS 禁用。
最重要的是，我无法通过 GUI 或终端命令关闭计算机。我必须进行物理重启或通过关闭 UPS 来物理切断电源。（错误附加到此问题）。我可以暂停计算机但无法重启它。每次我单击关机时，它都会转到“注销”屏幕。
系统监视器显示，两个核心即使在空闲时也以 80% 左右的效率运行。常规任务的效率通常在 5% 到 25% 之间。
自从这个问题出现以来，我就能听到风扇发出很大的呼呼声。
现在 Ubuntu 13.04 无法识别三星显示器并且将分辨率从 1440 x 900 更改为 1280 x 1024。
Unity 变得非常慢。无法识别外部硬盘。请帮忙。
不全新安装的话是否可以运行该操作系统？
谢谢。

确保/etc/sudoers文件中的以下几行完整无缺
Defaults env_reset
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
如果没有，您可以复制并粘贴这些行并保存文件，然后重新启动。
重启后您将不会再遇到这个问题。
