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
fglrx                2553695  0

But the startx still output the same message.

Any help or suggestion is really appreciated.

You appear to be using the 3.0 kernel - the default catalyst drivers that come with natty may not work with this kernel.

Can I suggest switching back to the standard natty kernel.

Alternatively, you should download and install Catalyst 11.7 or Catalyst 11.6 from the ATI website.

I am using the Oneiric Ocelot. Just after an upgrade(not distro upgrade), the problem occurs. –  user23287 Aug 14 '11 at 17:57
    
Sorry, I am not familiar with here... I will try to install AMD Catalyst 11.7! Thank you very much! –  user23287 Aug 14 '11 at 18:05
    
... ok - dont forget to uninstall fglrx first before installing catalyst 11.7. –  fossfreedom Aug 14 '11 at 18:06
    
Yes, I won't forget it, :-) –  user23287 Aug 14 '11 at 18:09

You have to run sudo aticonfig --initial once after the installation. If you haven't run this command yet it might be the cause of your problems

But I don't have this command on my machine. When I apt-get install fglrx, it only installed fglrx and fglrx-amdcccle. –  user23287 Aug 14 '11 at 17:52
    
did you try running it? –  danjjl Aug 14 '11 at 17:52
    
Where can I find this command? –  user23287 Aug 14 '11 at 17:53
    
When I try apt-cache search aticonfig, it shows nothing. –  user23287 Aug 14 '11 at 17:53
    
I hadn't realized you where running Linux 3.0 kernel you should follow what fossfreedom is telling you –  danjjl Aug 14 '11 at 17:54
