Hi,

I just put a 9200 in rather than a 7200 into my Ubuntu PC.

I typed in:
Code: 
sudo dpkg-reconfigure xserver-xorg

It took me through a load of options etc. and I set it all up and rebooted.

Now when I go into Ubuntu I get a 800x600 screen and everything kind of lags (graphical lag), just like the drivers haven't loaded for some reason.

Anyone got any idea how I can completely remove and completely reinstall the drivers please?

EDIT

I have tried complete removal and complete install using synaptic package manager, but that didn't re-do my xorg.conf file:(

Thanks,
Craig

you could just edit xorg.conf in a text editor (nano, vi, etc...)... if you're only getting 800x600 then just add the missing resolutions to the Section "Screen" part, ie
Code: 
    Subsection "Display"
        Depth       8
        Modes       "1280x1024" "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection
    Subsection "Display"
        Depth       16
        Modes       "1280x1024" "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection
    Subsection "Display"
        Depth       24
        Modes       "1280x1024" "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection

edit - also, just outta interest, in the "Device" section, do you have nvidia or nv in the Driver parameter?

If he's using an ATI he'll have neither, its still a valid point though- if its using the proprietary drivers it should have "fglrx" in the Device section.

It may be a plan to drop to a shell (Ctrl + Alt + F1), killall gdm, rmmod fglrx and radeon, reinstall them via apt-get, update your xorg.conf file and restart gdm.

That's what I'd do anyway :)

Click to expand...

or instead of using killall (which will work) just change run levels, ie # telinit 3.

Reinstalling the video card driver can always help too! More of a last resort.
