I have an Amitech Monitor which worked without any problem until I installed the NVidia VGA drivers.

Now I can't set up a resolution above 1024 x 768. If I try to set it higher the Desktop sort of becomes larger than the monitor. I can't see it all, and when I move the cursor to the edges, I can scroll the Desktop.

Not sure how to explain, but I hope you understand what i mean

I use MDK 10, but had the same problem with 9.2.
I have another monitor (KFC) which works fine in high resolutions.

Thank you

You have a modelines problem...

the generic drivers you were using probably had a good monitor modelines section, while the current one has a refresh rate to resolution setting that's out of the range of your monitor...

Check on Google for a linux modelines calculator. Input your refresh rates and monitor resolution so that you can get the proper settings. Then edit your XF86Config or XF86Config-4 file (depending on which distro you use) to use those settings instead of the ones that it's defaulting to.

Thank you for your answer.

I found a calculator at http://www.dkfz-heidelberg.de/spec/l...modeline2.cgi, but i have both XF86config and XF86Config-4, which one do I have to change?

Might as well change them both,... Although I think that in Mandy, the XFree86Config-4 file is the file that is being used in an XFree86 version 4.3.X environment.

I tried at http://xtiming.sourceforge.net/cgi-bin/xtiming.pl and at http://www.dkfz-heidelberg.de/spec/linux/modeline/ but none of them worked.

The specs. of my monitor are:

# 800 x 600 Non-Interlace, 100Hz
# 1024 x 768 Non-Interlace, 85Hz
# 1280 x 1024 Non-Interlace, 60Hz
# 30-70KHz horizontal scan frequency
# 50-150Hz vertical scan frequency
# 110MHz Dot Clock Frequency

I believe I have learned some about XFree86 as I worked with this problem, but I can't seem to solve it.

Post the monitor section and the screens section of your XF86Config-4.

Here goes:

Ok, try the following,
Replace the modes with what you need for your monitor, with the prefered mode first and the rest in decending order (left to right).

Okay, now it looks as so:


I'm still in 1024x768 mode. How's that?

Are you sure that the monitor supports modes bigger than 1024x768?
Do you have a link to the monitor specs?

I have used the resolution 1152x864 before I installed the NVidia drivers. Very strange.

The only specs are at this site: http://www.amitech.dk/support/starts...n=vis&aid=1775 but it's in danish. I believe the company is danish too.

Here are the specs. translated into my bad English :

That's all I know...

Ok try adding the following to your graphice device section section,

Hmm.. There was a change.

This time KDE tried to show a resolution of 1152x864, but in the usual screen-scrooling way. Just like when I try to force the resolution through.

Furthermore i received a lot of messages of programs which were crashed.

Oh, and the "Device section looked like this:
I also tried to remove the "DPMS" option, without any difference.

It's starting to look like 1152x864 is not fully supported by this monitor,
Usually all the modes supported are mentioned in these specs, and usually you want to run your display at 75Hz or better to avoid flicker (unless you have a LCD monitor).
