[SOLVED] Display does not fill the screen

Hello Forum.
When viewing the Desktop, I am not able to see the last 3" (or so) of the screen.
This problem occurred after I swapped out my Radeon X300 Graphics card with a PNY GeForce4 MX440se 64MB SDR PCI with TV-Out & RCA Video Card.

I removed the PNY GeForce4 card and re-installed the Radeon X300 card then restarted the computer and that is when I noticed that the last 3" of the display was missing, as well as the "Screenlets" that I had on my desktop.

I have searched the Linux Mint Forums and Posted this issue there. It was suggested that I search the xorg.conf Folder/Files and removed all that contained the entry Nvidia.
This did not solve the issue and beyond that, I don't know what else to do.

I am using Linux Mint 10 x86 on an AMD 64bit computer with 2 GIGs of RAM.
If any further information is needed please let me know.

Any help will be gratefully and enthusiastically accepted.

[EDIT] I just thought of something else that may (or may not) be important.
The Radeon X300 Graphics adapter that was originally installed in the computer when I installed Linux Mint 10 is a PCIE card while the PNY GeForce4 MX440se 64MB is a PCI card.
Just thought I should add this information.

Try going into system>administration>system monitor and manually adjust the setting to the proper resolution. Also try system>administration>additional drivers to make sure you have the proper driver loaded. Good luck!

Does your monitor have an "auto-adjust" feature on it's configuration menus? This will sometimes sort out strangely sized displays

@MASONTX
Thank you for your responce.
I tried to adjust the resolution manually-no joy.
All that happens is that the resolution grows or shrinks as I change the resolution settings up or down. The bottom 3" of my screen is still black.
Anything else that you can think of that I can try would be really appreciated.
Thanks again mate.

@elija
Thank you for the post. I tried your suggestion and selected the "auto-adjust" from the monitors configuration menu but it didn't work. I even reverted to "Factory Default" settings: that didn't work either.

I believe that the problem lies in the Kernel. I think what happened was that when I switched the ATI video card with the Nvidia card the Kernel saw that there was a new video card in the machine and installed the drivers for it.
The problem (I believe) is that when I switched back to the ATI card it somehow hosed the Kernel module for the video drivers. If that is even possible. I don't know, it's just a hunch. I am so new to Linux that very little of this makes any since to me.
Thanks for your help.

So we've eliminated a possible easier fix or two which is both good and bad!

Run the following commands on the terminal and copy / paste the output here. The first one will show what graphics card is being picked up as in use, which should be your ATi

Code:

lspci | grep -i vga

and then we look at what drivers you have running with

Code:

lsmod

elija.
Here's the output from the lspci | grep -i vga command:

Code:

lspci | grep -i vga 05:00.0 VGA compatible controller: ATI Technologies Inc RV370 5B60 [Radeon X300 (PCIE)]

And this is the output from the lsmod command:

By the way elija, thank you for such a quich response.
I am currently at work so my response may be a little slow but I will respond as I have the opportunity.

I can't see anything immediately wrong there; there don't appear to be any nvidia drivers lying around. I don't have an ATi card so I'm afraid that I may be a bit fuzzy on the details but the approach I would take if this happened with Nvidia is to:

open a terminal and run the following commands

Code:

cd /etc/X11 sudo mv xorg.conf xorg.saved

and then reboot. In the first command, that's a capital X and two ones. This will backup your display configuration and then the reboot will force Mint to use a default configuration. This won't be the proprietary drivers but will hopefully use the whole screen.

I would then use the Nvidia control panel to configure things up again. I hope that ATi provide one of those as they do make things easy.

This is kind of reaching the edges of my knowledge now, so hopefully a real guru will be along shortly

Thanks elija.
I will give this a try and then post the results.
If anything good has come from this it is that I am leaning Linux bits and pieces at a time. :o)

I'll let you know what happens.

I ran into a problem with the second command.
When I executed the command, sudo my xorg.conf xorg.saved this is what I got:

sudo: my: command not found

Did I do something wrong? Do I need to do this as root?
