After the boot loader completes the screen goes to the following image !

enter image description here My VGA : xfx geforce 9600 gso 1.5g

What should I do ?

I reinstalled 11.10 , 11.04 and 12.04 but I have my problem yet ! Another point is that I install ubuntu file system in another partition . Maybe Some Wrong config file is still in my home folder .

In my opinion it's not about driver problem because I have 11.10 with driver without any problem and I think this problem occurs when I try ubuntu 10.04 live CD !

I try ubuntu 12.04 final release too ! and the same problem occurred !

We're going to need a lot more information, but looks like a video driver problem at first glance. What's your video card model? What's the last thing you did before it started doing this? Also, is that a legit monitor or a TV going through HDMI? – Chuck R Feb 18 '12 at 21:52

When you boot the cd, hit the enter key when you see the little keyboard logo. Then hit F6, then [ESC] then add this to the end of the line on the bottom: vga=771 – Chuck R Mar 1 '12 at 2:54
Thanks ! Could you please explain more ? What happens then ? – mahdiar Mar 4 '12 at 12:21
It's forcing a certain video mode. Theoretically, it should prevent any proprietary drivers getting loaded and use your basic VGA video instead. Basically like video safe-mode. Thus, rending the CD bootable hopefully. – Chuck R Mar 4 '12 at 15:13

Try booting up using the "recovery mode" option. Then get the official drivers from (It's the GeForce 500 drivers)

Check out the comment to my answer here: Upgrade of nvidia graphics adapter fails on Lucid Lynx, low resolution only, no driver?

He points to a good page about how to get the drivers working

If you have to you can install the lynx text browser to navigate to those places. It's not fancy, but it gets the job done in a terminal. If this doesn't work try making a new partition and install it on that partition. If that doesn't work download ubuntu 11.10 again and install it from that.
