如果你是ATI顯卡的持有者，如果你用的是Ubuntu7.10，如果你真的迫不及待讓你的Ubuntu炫一把，那么就跟我來吧。

在Ubuntu7.10安裝3D驅動

(前提是你已經成功的安裝了顯卡驅動，注意：顯卡驅動成功并不代表3D驅動也裝上了，需要另外配置一下)

1把/etc/default/acpi-support文件的ENABLE_LAPTOP_MODE更改為true

$ sudo gedit  /etc/default/acpi-support

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

# Switch to laptop-mode on battery power - off by default as it causes odd

# hangs on some machines

ENABLE_LAPTOP_MODE=true

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

2把/etc/default/fglrx文件的FGLRX_ACPI_SWITCH_POWERSTATES更改為true

$ sudo gedit  /etc/default/fglrx

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

# Uncomment the next line to enable powerstate switching on ACPI

# events for lid open/close and AC adapter on/off

FGLRX_ACPI_SWITCH_POWERSTATES=true

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3把以下這部分從/etc/X11/xorg.conf文件中刪除。新的xorg服務啟用默認的"Composite"。

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

# Section "Extensions"

#        Option  "Composite" "0"

# EndSection

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

4把/usr/bin/compiz文件中的“# Driver whitelist”下的內容換成下面的內容(引號中的)

$ sudo gedit /usr/bin/compiz

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

WHITELIST="fglrx nvidia intel ati radeon i810"

# blacklist based on the pci ids

# BLACKLIST_PCIIDS="$T"

BLACKLIST_PCIIDS=""

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
