Blank screen problem with ubuntu 11.10

1. Why are you running cairodock with sudo?

2. sudo isn't even suitable for GUI apps like cairodock, you should use gksudo. Sudo doesn't set up the X environment correctly and will mangle the ownership of ICEauthority.

Thank you for reply.Can you please tell me what to do now.

my release level with 'uname -a; lsb_release -a'
uname -a : command not found
no LSB moduls are available.
Distributor ID : Ubuntu
description : Ubuntu 11.10

Codename : oneric

Also Memtest86 is passed no errors found.

Why are you running cairo dock with sudo?

When i was going to start Caciro-dock from dash it was not opening ...so i thught may be it will open thrugh cammand line.
Using( perheps it was the main problem ) "sudo" instead of "gksudo " some error came:

 $ sudo cairo-dock
Xlib: extention "GLX" missing on display "0.0".
(Cairo-dock-4821):GdkGLExt - WARNING **:Window system doesn't support Open GL.

for this solution have installed some file thrugh synaptic manager related to Cairo-dock...sorry i dont know the excetly files.

But after sucessfully installation of that files ...and restart the machine.
Ubuntu Not opening. Only Blank screen came.

By using recovery Mode it going to cammand line programme.this is

Any help for recover this problem.Thanks

What is the cammand to go back to normal Ubuntu ? I dont no the much about cammand line.

or I have to reinstall the Ubuntu ?

Thank in advance.

ok, lets clear something up first;

You don't run ALL commands in command line with sudo. You ONLY need sudo if you are editting or reading file you do not have access to or if you are running updates and junk like that. The config for cairo-dock is in your home folder. You HAVE access to this. You do not need sudo, so why you are using sudo is anyones guess as it is a) not needed and b) the incorrect way to run the app. If you run cairodock WITH sudo, you will be using the config held in /root and not YOUR home directory and is probably WHY you are getting the issues...

If you press CTRL+ALT+F7 you should switch to the GUI. If this doesn't work then if you tell us what happens when you reboot the OS we may be able to advise.

Thank you for your valuable advice.
(1) I have written that cairo-dock was not opening from dash or launcher that’s why I have used that command line.

  (2)Now after simply reboot ..only blank screen coming.

So the system is not booting to the desktop now? Is that correct?

yes , you are right.. !!The system is not booting to the desktop now..only blank screen coming.
