TwinView with different resolutions with Geforce 8200

normman · 12-22-2008, 09:13 PM

I have a Dell 2007fp (20") and and an Envision crt (17") with a geforce 8200 gpu. I installed NVidia's driver from here and used their utility to setup twinview. When I set both monitors to the same resolution, 1024 x 768, twinview works. However, when I set each monitor to a different resolution, my Envision works, but my Dell monitor turns off. That is, my Dell Monitor tells me it is not receiving a signal from the computer.

My xorg.conf with the same resolutions is

Code:

Could anyone tell me how to fix this?

Hi, welcome to LQ.

LQ has a fantastic search function that can save you time waiting for an answer,

many questions have been asked before and you may, be lucky to, find an answer quickly.

Regards, Glenn

see you 'round th' posts!

helpful xorg links....ftp://download.nvidia.com/XFree86/Li...ppendix-g.html

normman · 12-24-2008, 09:46 AM

I have looked at the information on ftp://download.nvidia.com/XFree86/Li...ppendix-g.html but I am still unable to understand why my monitor would turn off. Does anyone have any ideas?

GlennsPref · 12-24-2008, 05:35 PM

If you have 2 monitors, should the device names be monitor0 and monitor1?

Code:

Monitor        "Monitor0"

You need an entry for the second monitor, I think.

Happy Holidays, Glenn

Thanks, I will give it a try. I should note that with the xorg.conf I have posted, both monitors work. It is only when I change the resolution of the second monitor to 1152x864 that I get a problem. Both monitors work if I set the first(my CRT) to 1024x768 and the second(LCD) to 800x600. This would lead me to believe that my LCD "does not like" 1152x864, but it works at 1152x864 under Windows.

GlennsPref · 12-25-2008, 05:22 AM

Hi, you can change modes while the monitor is running.

ctrl+alt++(plus) to go up a resolution and ctrl+alt+-(ctrl+alt+minus) to go down.

If the monitor is just out of range you may have better luck that way.

If it works in windows, it should work with Linux.

Is the mode you describe listed in xorg.conf and is the frequency (refresh rate) fitting.

DPMS is what is being used to turn the monitor off for power saving.

But may also turn off if the signal is out of range.

It's a strange one, That's about all I can think of.

Can you use nvidia-settings or nvidia-xconfig(I haven't used this one) to change the config?

Cheers, Glenn

DiBosco · 12-25-2008, 11:58 AM

I would echo Glenn's suggestion of using nvidia-settings, I find that pretty good and intuitive.

normman · 12-25-2008, 04:48 PM

I have set it both through the nvidia utility and by editing the xorg.conf, but both produce the same result. I also manually set the refresh rate through the nvidia utility, but my LCD still turned off.

GlennsPref · 12-25-2008, 06:35 PM

There are examples for this.

I still think that the names of the monitors, and or screens, need to be different.

If you call monitor0, and set it up for the lcd, then call monitor0 again for the crt...

can you see what I mean?

Regards, Glenn

OK, sorry, I see you have monitor0 and monitor[0]. My mistake.
