Dell Inspiron M5010 and ubuntu 3D

[jolubaes]

Well, I just bought this computer with a video card Ati Radeon HD4250, I installed ubuntu 12.04 and when I the OS starts it just freeze, the only thing that I can do is to move the cursor, but nothing else work. In the other hand, if I start in 2D mode it works fine (without any 3D option of course).

This is what I have tried so far without succes:

1. I have tried the "ATI/AMD proprietary FGLRX grapics driver" in the additional drivers section

2. I also have tried the "ATI/AMD proprietary FGLRX grapics driver (post-release updates)" in the additional driver section

3. I also installed the driver provided by AMD... catalysits 12.4 and the newest catalyst 12.6

So far is the same result... no 3D options working

Any suggestion???
