请教:xorg 的配置问题--- startx起动不起来（关于鼠标的问题）

guloulan

:help
我按照The X Server Configuration HOWTO的文档安装完xorg，用下列命令：
# emerge xorg-x11
# env-update
# source /etc/profile
＃startx
出现错误
fatal IO error
如附件的图。

重新xorgconfig一下

鼠标配置的问题。
什么鼠标。。试试用
/dev/input/mice

鼠标是PS2的.
yanu兄,你说用/dev/input/mice ,我不了解，你能说具体一些吗？3q

在/etc/X11/xorg.conf文件中找
Core pointer's inputdevice section ，
把Option "Device" 这一行内容写为：
Option "Device" /dev/input/mice

我试了一下，成功了，谢谢neplusultra兄。
我又找了一下资料。如下：
X11 config file should now use /dev/input/mice for PS/2 and USB mice

One of the changes that a default udev configuration introduces is different organisation of the mouse device nodes. Previously, you would have had nodes such as /dev/psaux and /dev/mouse. You will now have nodes such as /dev/input/mouse0, /dev/input/mouse1, and a collective /dev/input/mice node which combines movements from all mice.

Since the old X configurations typically reference /dev/mouse or /dev/psaux then you may get an error similar to the one shown below when you attempt to start X11:

Code Listing 4.3: Common error when starting X on a udev system for the first time

(EE) xf86OpenSerial: Cannot open device /dev/mouse
        No such file or directory.
(EE) Mouse0: cannot open input device
(EE) PreInit failed for input device "Mouse0"
No core pointer

To correct this, open your X11 config in a text editor, and update the mouse InputDevice section to use the /dev/input/mice device. An example is shown below:

Code Listing 4.4: Opening your X11 config file

# nano -w /etc/X11/xorg.conf

Note: If you are still using XFree86, your config file will be /etc/X11/XF86Config

Code Listing 4.5: Sample mouse InputDevice section

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "rotocol" "auto"
        Option      "Device" "/dev/input/mice"
EndSection

Note: If you are using a serial mouse, the new device path will be /dev/tts/0 instead of /dev/ttyS0.

我也刚刚安装完Gentoo
有个经验与你分享一下
就是按照安装说明中大安装hotplug, 这样到后边鼠标支持滚轮会又问题
应该把hotplug换成coldplug. 然后Xorg.conf中设置为

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option            "rotocol" "IMPS/2"
        Option            "Device" "/dev/mouse"
        Option            "ZAxisMapping" "4 5"
        Option      "Emulate3Buttons" "no"
        Option      "Buttons" "5"
EndSection

先谢了，到时候我可要省了好多麻烦了。
第一次用gentoo，感受了用其它Linux版本所没有的乐趣。
