Bug Description
I am using Ubuntu on a Dell Inspiron 1721 with graphic card AMD M690T chipset with ATI Radeon X1270 integrated graphics.
Since the 11.10 release I am experiencing problems with the correct recognition of this card.
With Ubuntu 11.04 all the settings related to the graphic card were correct and the system was running perfectly.
From 11.10 and so far also with 12.04 alpha 2 (the version I used for this bug report) the system doesn't recognize the correct card. Under the window System Info, the Graphics value is Unknown.
The performances related to the graphics are really bad (example: if I open a .avi movie the vision is not fluid at all; the scrolling within Internet pages is not fluid at all). With 11.04 everything was running smoothly.
I guess it should be a simple error of driver assignment but of course I don't have the proper knowledge so I can only give you feedback. If there is something I can do to help I am willing to do it (but I am not an expert so I need to be guided).
Thanks for your efforts and passion, I really admire you guys :)

Hmm, actually X is finding your card just fine:
GraphicsCard:
Advanced Micro Devices [AMD] nee ATI RS690M [Radeon X1200 Series] [1002:791f] (prog-if 00 [VGA controller])
Subsystem: Dell Device [1028:01fd]
xrandr.txt indicates it's finding your display outputs okay, and has identified a full range of resolutions, and has found a preferred resolution and set it.
It also properly identified your monitor manufacturer:
[ 112.336] (II) RADEON(0): Manufacturer: LPL Model: 0 Serial#: 0
However it did not figure out the model or name of the monitor. Indeed, there is just garbage here:
[ 112.336] (II) RADEON(0): v_active: 900 v_sync: 901 v_sync_end 904 v_blanking: 912 v_border: 0
[ 112.336] (II) RADEON(0): UM606171WX2
[ 112.336] (II) RADEON(0): '8CKjÄÿ
[ 112.336] (II) RADEON(0): EDID (in hex):
This is what it should look like (well, how it looks for me):
[ 5.733] (II) RADEON(0): v_active: 350 v_sync: 387 v_sync_end 389 v_blanking: 449 v_border: 0
[ 5.733] (II) RADEON(0): Ranges: V min: 56 V max: 76 Hz, H min: 30 H max: 83 kHz, PixClock max 175 MHz
[ 5.733] (II) RADEON(0): Monitor name: BenQ 241W
[ 5.733] (II) RADEON(0): EDID (in hex):
That's probably why you see the display shown as 'Unknown'.
So, I think when you say "wrong graphic card drivers" what you really mean is "Wrongly identified monitor". If that's incorrect please explain further.
