cannot get a resolution to 1280x1024

im on a big 19 inch dell monitor (the p991) which i know can do atleast 1280x1024 at 75 or 85khz

the only way to get my resolution to 1280x1024 is to edit the xorg.conf file to have a vertical refresh rate of 60 or lower, and that kills my eyes

here is some of my xorg.conf

Code:

Section "Monitor"



    Identifier  "UltraScan P911"



# HorizSync is in kHz unless units are specified.

# HorizSync may be a comma separated list of discrete values, or a

# comma separated list of ranges of values.

# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S

# USER MANUAL FOR THE CORRECT NUMBERS.



    HorizSync  64,50-60



#    HorizSync        30-64        # multisync

#    HorizSync        31.5, 35.2    # multiple fixed sync frequencies

#    HorizSync        15-25, 30-50  # multiple ranges of sync frequencies



# VertRefresh is in Hz unless units are specified.

# VertRefresh may be a comma separated list of discrete values, or a

# comma separated list of ranges of values.

# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S

# USER MANUAL FOR THE CORRECT NUMBERS.



    VertRefresh 70-100

i have current nvidia drivers installed to, (7174, i think) and i can tell they are working because i see the nvidia splash screen

any help would be greatly appreciated

There is a tool out there that if you supply the specs of the monitor it should produce the need info to insert into the xorg.conf file. I cannot remember it right now. If I do I will post.

Another thought is to boot up with a live CD like knoppix and see if you can change the settings to the way you want it and then look at its xorg.conf and compare.

You need both the proper HorizSync and VertRefresh for your monitor.
Check the manufacturer of you monitor, or it's manual.

http://support.dell.com/support/edoc...91/en/spec.htm

those are the specs

it gives an 'optimal' res of 1280 x 1024 at 85 Hz
in the table it shows a horizontal res of something like 80-90hz

so it should run at those resolutions

ill look into knoppix to check if it works in that

According to Dell's specs page, your horizontal and vertical refresh numbers are way off. That *will* prevent you from using the monitor's upper resolutions and refresh rates.

I'd suggest you run through xorgconfig and set them correctly....

Forget Knoppix...that's a waste of time, and not necessary.
Set the Vert to 48 - 120 and the Horz to 30 -107
If that looks good at 1280 x 1024, then issue "xrandr" and
see what you get for the values, like this:

Code:

mingdao@james:~$ xrandr

 SZ:    Pixels          Physical      Refresh

*0  1024 x 768    ( 302mm x 232mm )  *75  70  60  

 1    800 x 600    ( 302mm x 232mm )  75  72  60  56  

 2    640 x 480    ( 302mm x 232mm )  75  73  60  

 3    832 x 624    ( 302mm x 232mm )  75  

 4    512 x 384    ( 302mm x 232mm )  75  70  60  

 5    416 x 312    ( 302mm x 232mm )  75  

 6    400 x 300    ( 302mm x 232mm )  75  72  60  56  

 7    320 x 240    ( 302mm x 232mm )  75  73  60  

Current rotation - normal

Current reflection - none

Rotations possible - normal 

Reflections possible - none

mingdao@james:~$

Then you can adjust your rates if need be, or you could just
use the table Dell published, and start with 1280 x 1024 with
Horizontal 91.2 Vertical 85.0

This is all more trial and error in *nix than in Windoze, where
you have that config screen that let's you adjust them via a
GUI rather than in a term. No matter, you'll get it right soon.
You're a Slacker, mate, so do it in a term. ;-)

And btw...don't reboot your computer when you make these
changes, just restart the X server. Either via your WM/DE's
menu, or with Ctrl+Alt+Bksp

thanks chinaman!
even gotting it working at 1600x1200!

Good on yah! I'm happy, too!

My little 15" LCD won't go above 1024x768. Looks like a postage stamp...I'm envious :-)

Hi, glad you are sorted.

I used this:- http://www.sh.nu/nvidia/gtf.php to generate a custom modeline entry for my xorg.conf, as despite entering the correct horz and vert frequency, I could not get the refresh rates I knew I should have available at the higher resolutions. Now get 1280 x 1024 at the max refresh of 85hz.
