Bad Resolution/EDID problem


Hey, im trying to get the right resolution on my box: 2058x1152
but it seems that there is something wrong with EDID.
Slackware version: 12.0

I have installed correct nvidia drivers, and tried editing xorg.conf, but none of those help.

xorg.conf
http://pastebin.org/2972

xorg.0.log
http://pastebin.org/2973


so after i saw
(WW) NVIDIA(GPU-0): Unable to read EDID for display device CRT-0

i added the option
Option "UseEdid" "False"

but it doesn't seem to help anyway.

Any help/advice is appreciated.

Try putting the Option in the Device section. That's where I have my EDID settings.

Cheers.

Code:
#
(**) NVIDIA(0): Option "UseEDID" "False"
#
(**) NVIDIA(0): Enabling RENDER acceleration
#
(**) NVIDIA(0): Ignoring EDIDs

Doesn't that mean that it's working? if not ill try.

Show me the manufacturer's page for the specifications of your video card.

Edit: Forgot to answer your why...

Because I've never heard of a 2058x1152 resolution. Neither has Google
except for your post. And a CRT isn't supposed to do over 1920 1440
with that card. And not using EDID means you don't let the card poll
the monitor and work out what you can't figure out.

Try the following in your Device section

Option "ModeValidation" "NoEdidDFPMaxSizeCheck, NoMaxPClkCheck"



Here's my Device section in xorg.conf

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "ModeValidation" "NoEdidDFPMaxSizeCheck, NoMaxPClkCheck"
EndSection

Question

from OP's xorg.O.log
line 375

" (II) Setting vga for screen 0. "

Does this mean you are using VGA D-Sub cable?

I think this monitors unusually high resolution requires the bandwidth of a dual-link DVI cable. Single-link may be on the boarderline.
The DVI wiki page seems unclear on the matter.

Your log has CRT ... my mistake.

The only GeForce 8600 GT (84) I find is a Gigabyte. Check it's modes.

I still think you need the EDID:
Code:
#
(WW) NVIDIA(0): Unable to get display device CRT-0's EDID; cannot compute DPI
#
(WW) NVIDIA(0):     from CRT-0's EDID.
and need it in the proper section.

Your monitor is 16:9.
16 / 9 = 1.7777

Your resolution should be 2048 x 1152.
2048 / 1152 = 1.7777

2058 / 1152 = 1.786

What type of cable and/or adaptor are you using?

First, as root issue "rm /etc/X11/xorg.conf" and then "sh NVIDIA-Linux-x86_64-185.18.14-pkg2.run"
and at the end let the driver make you a new "/etc/X11/xorg.conf".

Then when you boot, issue "xrandr" and see what it tells you. If you still don't get what you
want, post back the "xrandr" output, the nvidia generated "/etc/X11/xorg.conf" and the new
"/var/log/nvidia-installer.log".

Samsung does not list a 2343nw monitor, nor do they have good
information at all. Their monitors are good middle of the line
monitors, but you'd better hope you got a manual with it.

Only thing I can say is try a digital cable. The DVI adapter
does not make the VGA cable digital ... it's still analog.
