为什么我的屏幕变灰了？

我刚刚在笔记本电脑上安装了 Ubuntu 11.04。但是，很多时候系统变得非常慢，窗口开始闪烁灰色。然后系统几乎没有响应……这种情况每隔大约 5 分钟就会出现一次。当我运行命令时，top看起来 Xorg 命令占用了大部分 CPU，这时系统变得很疯狂。

我正在使用 HP Compaq 6720s。

lspci | grep VGA

您的系统完全有能力运行 ubuntu 和所有 3D 内容。我有同样的显卡，但使用的是旧赛扬处理器和较少的内存，一切正常。我建议您安装显卡的驱动程序：

sudo aptitude reinstall xserver-xorg-video-intel

另外，安装 driconf 和 mesa-utils 并查看您是否具有硬件 3d 加速：

glxinfo | grep direct

应该输出“是”，除非你的卡没有被检测到

driconf

将帮助您配置您的图形。
