求助：compiz不能启动

[荣辱不惊]

点菜单compiz fusion icon没有反应，终端输入 compiz提示
WARNING: Application calling GLX 1.3 function "glXCreatePixmap" when GLX 1.3 is not supported! This is an application bug!
如何解决？谢谢！
（10.04LTS，compizconfig设置管理器和Emerald Themer正常，用新立得把所有含compiz的重装了一遍，还是不行 ）

This is an application bug!

说得比较明了了。

fusion icon 是py的。先打到再说。

[荣辱不惊]

终端输入：fusion-icon显示如下（面板上没有出现fusion－icon图标）
* Detected Session: gnome
* Searching for installed applications...
Traceback (most recent call last):
File "/usr/bin/fusion-icon", line 57, in <module>

self.write(open(self.config_file, 'w'))
IOError: [Errno 13] Permission denied: '/home/lyh/.config/compiz/fusion-icon'

转到.config文件夹下发现compiz文件夹的所有者为root，觉得似乎不对
(前几天进不了桌面，把.gconf 和 .config都删了，并用root登入过一次，不知是否有关？）
于是sudo chown lyh .config/compiz将其改为自己
再输入fusion-icon提示如下（面板上出现了fusion－icon图标，屏幕闪了两下，有一种重启桌面的感觉）

显示两条WARNING我想是因为输入了两次命令的原因，top显示compiz已经在运行了
继续尝试自己修复，也请高手指点

[荣辱不惊]

输入fusion-icon --no-start（跟菜单compiz fusino icon的属性中看到的命令一样）显示如下
* Detected Session: gnome
* Searching for installed applications...
* Intel detected, exporting: INTEL_BATCH=1
* Using the GTK Interface
一切正常！
为何要加 --no-start参数？求解
