does anybody know how to change drivers in ubuntu

[dam_it_chirs]

My video driver is a radeon 9250 and the computer is reading it radeon 9200
I went to add/remove programs and found the drivers I need and installed them but no change
can anybody help

After doing a lot of reading on the ubuntu forums I ran across this script

http://albertomilone.com/nvidia_scripts1.html

This guy is one of the ubuntu grurus for video cards.  I haven't tried the Envy script on an ATI box (might just do that when I reinstall my laptop) but it worked, first time "out of the box" for the Nvidia 6500 drivers.

Where do you see it "reading" the video card as radeon 9200?  What does the output of lspci say about your video card?

[jcd]

If you have not done it already, to reconfigure your system to use the closed source ATI video driver you might have to run:

# dpkg-reconfigure xserver-xorg

It will certainly default to the "vesa" driver and you might need to force it to ATI/radeon.

I hope it helps

none of them worked
the envy made me restart my computer and the command is not working

The command 'lspci' is not working?  How are you trying to run it?  Again, where did you see that your video card was a different model exactly?

[thynk]

I may have missed what you were asking.  In your /etc/X11/xorg.conf and the xorg.pluto.conf you can manually change the drivers from ati to fglrx and reboot or restart X.  If that doesn't work, you can always change them back to ATI.  You might also wish to edit the cards file (you'll have to search for forums for the full path, my memory hasn't had a full cup of coffee yet) and change any reference of the ati to fglrx or visa-versa. 

Maybe taking a step backwards, but what issues are you seeing that are making you want to change the driver, exactly and where do you want the driver changed. 9200 vs 9250, is there a significant difference in the cards that you're not getting the results you wish with the 9200 driver?
