Ati driver installation problem on Mobilyty HD Radeon 4250

Ati driver installation problem on Mobilyty HD Radeon 4250

I have laptop Compaq Presario CQ-56 with Mobility Radeon 4250 . I use
Ubuntu 12.04 LTS , I used this guide (
https://help.ubuntu.com/community/BinaryDriverHowto/ATI ) from step 3.1 to
step with fglrxinfo , and i saw in my terminal info about chipset GPU only
. I repaired broken packages from Synaptic , but after rebooting the
system i tried this command in terminal "gksudo amdcccle" and now i see
one window where sad i don't have any installed driver in my machine ...
and if i use fglrxinfo i see this
mtrx@Anaconda:~$ fglrxinfo
X Error of failed request: BadRequest (invalid request code or no such
operation)
Major opcode of failed request: 153 (GLX)
Minor opcode of failed request: 19 (X_GLXQueryServerString)
Serial number of failed request: 12
Current serial number in output stream: 12
If i start from System settings Additional Drivers i see "No proprietary
drivers are in use on this system" Thank you .
