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 .

open your terminal and type as 

sudo apt-get install --reinstall fglrx-driver

Then reboot your PC , after doing the reboot execute this command

sudo aticonfig --initial

hope that helps.
