Image is displayed fuzzy.

Hi.
I have previously installed another graphics card and now when I switched back something is wrong. The image is fuzzy in Ubuntu but it is crisp in Windows 7-
So how can I fix the graphics drivers so that the picture is crisp?

Edit: I have typed "Nvidia" in the dash and clicked on "Nvidia X Server Settings". The resolution 1280x1024 works good.

Edit2: Follow these steps to fix this problem:

Turn off computer. Turn off the PSU. Unplug the power cord.
Open the computer case side panel so that you can acess the harddrive.
Unplug the primary harddrive (both sata and power) and wait for 5 seconds.
Plug both cables back in to the harddrive.
Close the computer case side panel.
Plug in the power cord and turn on the PSU.
Now you can start the computer and it should work normally.


This was the way I fixed my computer. I can now set the native high definition resolution. Read my other thread to understand what other problems you can fix by this guide. Link: http://ubuntuforums.org/showthread.php?t=2136603

The computer with Ubuntu is now displaying a fuzzy image when I run the native resolution of 1920x1200. I had to set the resolution down to 1680x1050 to be able to watch the screen. The problem reoccurred after I turned off the monitor and later turned it on again.

How should I fix this problem so that the native resolution works clearly?
