gnome shell已经完全没有compiz的。
你的以现在的信息，看不出什么什么问题弄的
nautilus的问题，用终端输出看看有什么东西好点

终端看那不出什么，只能sudo nautilus打开

Initializing nautilus-open-terminal extension
Initializing nautilus-image-converter extension
Initializing nautilus-ideviceinfo extension
Initializing nautilus-gdu extension
Initializing nautilus-dropbox 0.6.8
** (nautilus:9737): DEBUG: Syncdaemon not running, waiting for it to start in NameOwnerChanged

我查到了些资料，你先检查你安装了其他桌面环境了么？然后请用系统原来的登录器登录deepin环境
还有检查你自己目录的权限

其他桌面环境已经卸载删去，用deepin登录依旧有问题而且出现桌面是蓝色，无法更改壁纸，任务栏模糊

你安装过kde么？现在使用的是kde的登录管理器？
deepin环境，应该是shell和驱动的问题，现在又明显冲突了。。。很多人遇到啊。
