help! :) cannot do 1280x1024

[natel]

**posted first on the NVIDIA forum, not linux NVIDIA my bad**

Good day ladys, gents.

My problem is

I can only seem to get 1280x960

I have a NEC accusyn 75F that does 1280x1024
Tech Specs:
Hsync: 31-70kHz
Vsync: 55-120Hz

Reading through these forums and I'm still getting the trouble.

(from xdpyinfo)
screen #0:
dimensions: 1280x960 pixels (332x241 millimeters)
resolution: 98x101 dots per inch
--

bash-2.05b$ cat /var/log/XFree86.0.log | grep Monitor
(**) | |-->Monitor "Monitor0"
(II) NVIDIA(0): Monitor0: Using hsync range of 31.00-70.00 kHz
(II) NVIDIA(0): Monitor0: Using vrefresh range of 55.00-120.00 Hz
(WW) (1400x1050,Monitor0) mode clock 122MHz exceeds DDC maximum 110MHz

from XF86Config

(tried with just "1280x1024" also)

Hm

Now, I dont know where I am going wrong here.
Any feed back would be great. Need more info from me? I will give all that I can. Thank you.

Nate :confused:

The 'Modes' line seems a little bit weird. Which distro are you using? AFAIK, there's no need to specify the refresh rate nor the driver (VESA). In Red Hat it should look a bit more like this:

Depth 24
Modes 1280x1024 1024x768 800x600 640x480

Depth 16
Modes 1280x1024 1024x768 800x600 640x480

Depth 8
Modes 1280x1024 1024x768 800x600 640x480

In that way you allow the programs to set 256 colors, 16 or 32 bit at all the resolutions.

If you want to set the default mode to be 1280x1024, I don't quite remember where's the line, but it's not there.

Another thing you shopuld consider is that there may be two Config files: the XF86Config and the XF86Config-4. Maybe you're editing the wrong one.

Don't be ashamed to ask. We all had to learn in the same way. ;)

Scratch out the two modes ""1280x1024@60Hz(VESA)" "1280x1024@60""

even with those not there.. or just:
modes "1280x1024"
it still goes to 1280x960

I know I'm editing the right config (XF86Config)

I should state, I am running slack 8.1 2.4.19
VESA I got 1280x1024, I've adjusted the refresh rates like...

Lost..

Thanks again :)

Attached is my X.0.log :)

[Anthaus]

Your log just states that it cannot do 1280x1024. It definitely has something to do with the XF86Config.

Do you have the XF86Config-4?

Have you been able to use nVidia's GLX?

Can you post your XF86Config files (both), please?

[natel]

I dont have XF86Config-4
(cannot 'locate' it -- not there :)

No prob doing 1280x1024 with the nv driver. and also in windows :)

[natel]

Option "IgnoreEDID" "boolean"
Disable probing of EDID (Extended Display Identification
Data) from your monitor. Requested modes are compared
against values gotten from your monitor EDIDs (if any)
during mode validation. Some monitors are known to lie
about their own capabilities. Ignoring the values that
the monitor gives may help get a certain mode validated.
On the other hand, this may be dangerous if you don't
know what you are doing. Default: Use EDIDs.

Option "NoDDC" "boolean"

Now, HOW dangerous is this option? :)
Works good. but does it have long term effects?

[Anthaus]

Most modern monitors protect themselves agains invalid refresh rates (they go low-power). I don't think it should be a prob.
