如何找出X11驱动系统正在使用的驱动程序？

因为我的芯片openchrome是最好的驱动，但我怀疑系统没有使用它。我只需要至少二维加速。

我怎么查？

这就是我从cat /var/log/Xorg.7.log | grep driver中发现的：

[    54.147]    X.Org XInput driver : 12.3
[    55.167] (==) Matched openchrome as autoconfigured driver 0
[    55.167] (==) Matched vesa as autoconfigured driver 1
[    55.167] (==) Matched fbdev as autoconfigured driver 2

据我所知，它没有使用openchrome。

这里是lspci | grep VGA：

00:01.0 VGA compatible controller: VIA Technologies, Inc. VX800/VX820 Chrome 9 HC3 Integrated Graphics (rev 11)

(这是一个瘦客户端。)

这是grep -E '(\(WW|\(EE)' /var/log/Xorg.7.log的输出：

Answer 1

要回答您最初的问题，是的，您使用的是OpenChrome驱动程序。不幸的是，它对你的芯片组的支持很少，如果不是最近的话就更糟了。到目前为止，您应该能够获得基本的2D，和任何2D加速支持您的芯片组。这取决于你说它是否“足够好”，或值得改变为更好的东西。

Openchrome在09‘之后经历了很多改进，发行版总是以许多版本过时而告终。Chrome 9的支持在最近的OpenChrome版本中得到了改进，这将提供更好的性能/稳定性/特性。

此外，Chrome 9 HC3还有一个专有的驱动程序，但并不是每个发行版都有可用的包。对于过时的发行版来说，这是更好的选择。基本上，哪种方式取决于发行版的发布，以及/或您是否编译了自己。

我可能会告诉你一个简单的升级选项，需要发行版知道。如果你不知道这有助于识别LSB的发布

## outdated distro's might not support this command    
lsb_release -a

## Most Distro's will display release, in an /etc file.
cat /etc/*release

检查视频覆盖

## Still verify Xv works, whenever you get X running again.
## xvinfo | head -10

Answer 2

取决于您在X日志位置上的系统，在Linux：/var/log/Xorg.0.log上可能会有所不同。如果您搜索单词driver，您将能够看到这样的行：

[    34.252] (==) Matched fglrx as autoconfigured driver 0
[    34.252] (==) Matched ati as autoconfigured driver 1
[    34.252] (==) Matched vesa as autoconfigured driver 2
[    34.252] (==) Matched fbdev as autoconfigured driver 3

这意味着它将使用其中一个驱动程序。

您还可以查看：

/etc/X11/xorg.conf

搜索Device部分，它将告诉您它将使用哪个驱动程序。你也可以尝试做：

sudo X -configure

创建/etc/X11/xorg.conf

根据您的进一步评论，您应该查看此页获得更多指导。您可能需要使用10.04发行版这样的选项来查看是否可以让它工作。
