Unwanted Resolutions

[undrwater]

Hello!
I've got Gentoo running with the nv accellerated drivers working properly, with one caveat:

In the XF86Config file i specified 1152x864 resolution (which I use for my M$ resolution); but when i startx i get 1024x768.

Using the CTRL+ALT+'+/-' key combos takes me through 800x600 and 640x480....but never 1152x864.

Now when i say i specified that resolution, i mean that i eliminated all other resolutions in the Config file.

Where is X getting these other resolutions?

TIA

Does Gentoo use XF86Config, or XF86Config-4? In other words, are you sure you changed the right config file?

</dumb questions>

There might be the equivalent of a hardwired list of resolutions in the XFree86 binary, but I kind of doubt that... maybe there are clues in the X log file? /var/log/XFree86.0.log

Thanks for the response...

Gentoo doesn't use XF86Config-4 (i checked), but i will definately check the log.

I've done a lot of googling about this but it's hard to find an answer (kind of hard to describe the problem so that google returns valid responses, too).

I'll post once i check my log.

OK...checked the log and found some problems...
here's some of the text from the log:

There it is...not sure what exactly is happening there....but i hope someone can help...

(II) NVIDIA(0): Not using default mode "1152x864" (hsync out of range) And then later,

(II) NVIDIA(0): Not using mode "1152x864" (no mode of this name) I'm not sure why it recognizes the mode once (when it says hsync out of range), then doesn't later, but I think you can fix it if you can generate a modeline for that resolution. I know there are programs to help with that, but I don't know where to find them -- they've been posted here a couple of times before, though, so maybe if you search around a bit for "modeline generator" or something? I guess I don't know that that would help, but it seems likely that it would.

maybe you can use one of them.....

Yeah, try the modeline, I guess.

(WW) NVIDIA(0): Failure reading EDID parameters for display device 0.
(II) NVIDIA(0): optiquest q71: Using hsync range of 31.50-64.30 kHz
(II) NVIDIA(0): optiquest q71: Using vrefresh range of 50.00-90.00 Hz

These are not correct. 30-60 and 50-90 would be sensible sync ranges for a 14" monitor, maybe a 15".

According to:

http://www.viewsonic.com/support/crt_q75.htm

Your settings should be:

Frequency Fh:30-86kHz, Fv:50-160Hz

Open up your XF86Config and make sure there are HorizSync and VertRefresh lines in your monitor info, and make sure they match the info from Viewsonic. You will then find that max refresh rates for the resolution you indicate will automagically be selected. No modelines needed.

"Your settings should be:

Frequency Fh:30-86kHz, Fv:50-160Hz"

Inserted this into XF86Config and now i'm looking at you through 1152x864 resolution.

Thanks!!
