安装xgl以后，无法正常起动Xgl

ooio_karl

我是按照wiki中这篇文章来做的：http://gentoo-wiki.com/HOWTO_XGL
安装完成之后，使用下面的命令在gnome-term下启动：

1. Xgl :1 -ac -accel glx:pbuffer -accel xv:pbuffer -fp /usr/share/fonts/misc,/usr/share/fonts/TrueType

复制代码

只出现了一个蓝色的窗口，然后什么都没有了，不知道是不是我有什么地方做的不对？出现了下面的提示：

2. Karl ~ # Xgl :1 -ac -accel glx:pbuffer -accel xv:pbuffer -fp /usr/share/fonts/misc,/usr/share/fonts/TrueType
3. No matching visual for __GLcontextMode with visual class = 4 (32770), nplanes = 24
4. No matching visual for __GLcontextMode with visual class = 4 (32770), nplanes = 24

复制代码

另外，当我命令行状态下执行 startxgl gnome ati命令以后，屏幕变成全黑色，但是可以通过鼠标旋转屏幕，能够看到正方体上面白色中背景和Freedesktop.org标志，也能够看到下面的白色背景，但是中间4个面是全黑色的，没有任何图象和窗口，不知到是什么问题？

Partial distortion
It is usually accompanied with the following error messages:

1. No matching visual for __GLcontextMode with visual class = 4 (32770), nplanes = 24
   
2. No matching visual for __GLcontextMode with visual class = 4 (32770), nplanes = 24

复制代码

1. NOTE: __GLcontextMode is due to Color Depth, setting it to 24 solves the problem with these messages.

Partial distortion of the screen has also been reported. This seems to be an issue when using 16 bit color depth. A workaround is to use 24 bit color depth.

Increasing VideoRam from 16384 to

1. VideoRam  32768

复制代码

allowed my to set my i810 to 24bit color depth.
