I can't boot into the graphical interface. If I try to startx in the text mode. It outputs the following messages:

But I have successfully installed fglrx by "apt-get install fglrx". If I manually insmod fglrx.so, I can see:

$ lsmod | grep fglrx

But the startx still output the same message.

Any help or suggestion is really appreciated.
