设置成随系统启动beryl失败。手动在终端输入beryl-manager出来：
qq@ubuntu:~$ sudo beryl-manager
Password:
qq@ubuntu:~$ Xlib: extension "XFree86-DRI" missing on display ":0.0".
XGL Absent, checking for NVIDIA

xgl没有启动吧？

[beiling]

ls的能说的详细点吗？如何启动？

[windywinter]

MS这篇文章非常适合你看：
viewtopic.php?t=35403

[beiling]

还是不行。该了系统很卡，又改回来了

[eexpress]

sudo？为什么？？

[beiling]

sudo beryl-manager?

[windywinter]

beryl-manager不需要sudo

[beiling]

Xlib: extension "XFree86-DRI" missing on display ":0.0".
这是什么意思？

另外现在我每次启动X时开始显示器黑屏，显示：信号超出范围。

sudo习惯了。不需要root权限的情况下用sudo会有哪些问题呢？
