如何找出正在使用的 X11 驅動系統？

如何找出正在使用的 X11 驅動系統？

因為我的晶片openchrome是最好的驅動程序，但我懷疑系統沒有使用它。我只需要至少 2D 加速。

我該如何檢查？

這是我從中發現的cat /var/log/Xorg.7.log | grep driver：

[    55.167] (==) Matched openchrome as autoconfigured driver 0

據我所知，它沒有使用openchrome.

這是lspci | grep VGA：

（這是一個瘦客戶端。）

這是輸出grep -E '(\(WW|\(EE)' /var/log/Xorg.7.log：

要回答您最初的問題，是的，您正在使用 OpenChrome 驅動程序。不幸的是，它對您的晶片組的支持很少，如果它不是最新的，甚至更少。到目前為止，您應該能夠獲得 Basic 2D，並且您的晶片組支持任何 2D 加速。由您決定它是否“足夠好”，或者是否值得換成更好的東西。

Openchrome 在 09 之後經歷了很多改進，並且發行版總是以許多版本過時而告終。Chrome 9 支持在最近的 OpenChrome 版本中得到了改進，應該會提供更好的性能/穩定性/功能。

此外，Chrome 9 HC3 還存在專有驅動程序，但並非每個發行版都有可用的軟體包。對於過時的發行版，這是更好的選擇。基本上，走哪條路取決於您的發行版，和/或您是否自己編譯。

我也許可以指導您使用簡單的升級選項，需要發行版才能知道。如果您不知道這有助於辨識 LSB 版本

## outdated distro's might not support this command    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

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

檢查影片疊加

## Still verify Xv works, whenever you get X running again.
