安装显卡驱动程序：“ATI RV370 上的 Gallium 0.4”和“Mobile Intel® GM45 Express Chipset”

我的台式机和笔记本电脑的显卡驱动程序都存在问题（台式机上的“ATI RV370 上的 Gallium 0.4”和 Latitude E6500 上的“Mobile Intel® GM45 Express Chipset”不同）。我认为驱动程序无法正常工作，因为在安装 mesa-utils 之前无法识别显卡。

那么首先如何测试显卡性能呢？

其次，当我确定驱动程序未安装时，如何安装它们（对于像我这样的 Linux 新手来说，生产商网站上的说明很难理解）

我正在使用 Ubuntu 12.04

先感谢您！

怎样测试显卡性能？

如果您安装了该mesa-utils软件包，可以使用以下命令进行检查glxgears：

$ glxgears 
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
radeon: Acquired access to Hyper-Z.
291 frames in 5.0 seconds = 58.022 FPS

当我确定驱动程序未安装时，如何安装它们

你有几种方法：

然后lspci -nnkvv -s添加域：bus：slot.function，就我的情况而言00:03:00.0：

sudo lspci -nnkvv -s 00:03:00.0

这里最重要的部分是最后一行“内核驱动程序正在使用中”。

您还可以检查日志文件：

sudo grep -E 'dri|drm' /var/log/dmesg /var/log/Xorg.0.log

这lshw -c video：

$ sudo lshw -c video
