nvidia drivers, no max resolution

Message

I followed the guide for nvidia drivers here: http://www.gentoo.org/doc/en/nvidia-guide.xml

for an nvidia NV5M64 Riva TNT2 PCI video card, using nvidia-legacy-drivers, but can only get max resolution of 1280x1024 on my Dell E228WFP 22" monitor, which supports 1680x1050, I can get that resolution using Redhat/CentOS/Fedora drivers with the same hardware (swap hard drive in bay and boot). I have to guess nvidia only has 2 publicly available drivers (legacy/current), does Redhat have something special? The newer nvidia driver doesn't help, I tried that. My xorg.conf file shows:

-------------------------------------
Section "Module"
Load "ddc"
Load "vbe"

EndSubSection

Am I missing something terribly obvious...hopefully?

RedHat does not have a special driver. All distros use the nvidia drivers as-is. The fault is probably with your xorg.conf - why restrict HorizSync and VertRefresh? Don't restrict it to 75.0, you're ignoring the potential for rounding errors, e.g 75.0001.

I guess your graphics card / monitor supports 85 Hz on that resolution?

Code: Select all

gtf 1680 1050 85

# 1680x1050 @ 85.00 Hz (GTF) hsync: 93.75 kHz; pclk: 214.51 MHz
Modeline "1680x1050_85.00" 214.51 1680 1800 1984 2288 1050 1051 1054 1103 -HSync +Vsync

just enter

gtf X Y Hz

where X is horizontal, Y is vertical, Hz is refresh rate

you can also replace:

Code: Select all

 HorizSync 30.0 - 83.0

with

Code: Select all

 HorizSync 30.0 - 93.75

and

Code: Select all

 VertRefresh 56.0 - 75.0

with

Code: Select all

 VertRefresh 56.0-214.51

this should enable you to get that high resolution ...

if I wrote something wrong, just try out the modeline ...

... now good luck

I ran:

Code: Select all

gtf 1680 1050 60

based on Dell's information here: http://support.dell.com/support/edocs/m ... ifications

and got:

# 1680x1050 @ 60.00 Hz (GTF) hsync: 65.22 kHz; pclk: 147.14 MHz
Modeline "1680x1050_60.00" 147.14 1680 1784 1968 2256 1050 1051 1054 1087 -HSync +Vsync

so set xorg.conf to:

Code: Select all

 #HorizSync    28.0 - 96.0
 #attemtp 2HorizSync    29.0 - 84.0
 #attemp 3 HorizSync  29.0 - 93.76
 HorizSync  29.0 - 65.22
 #VertRefresh  50.0 - 75.0
 #attempt2 VertRefresh  55.0 - 76.0
 #attempt3 VertRefresh  55.0 - 214.51
  VertRefresh  55.0 - 147.14

in /var/log/Xorg.0.log

I don't know why it doesn't seem to be attempting 1680x1050 according to the log file?

Thanks for any info.

Either the EDID info being returned by the monitor is bogus or the specifications are. Xorg is using the EDID information as gospel and adjusting the specs. Since the EDID information says you are not capable of that resolution you can't use it.

Check to see if there is an NVIDIA driver setting that disables EDID.

Moved from Installing Gentoo to Desktop Environments.
xorg stuff, so moved here.

unclecameron · Post by **unclecameron** » Thu May 24, 2007 10:06 pm

I've attempted to disable EDID based on info. here: http://us.download.nvidia.com/XFree86/L ... dix-d.html

so I added the following lines to my xorg.conf
------------------------
Section "Device"
Identifier "Card0"
Driver "nvidia"
VendorName "All"
BoardName "All"
# BusID "PCI:1:0:0"
Option "UseEDID" "False"
Option "UseEdidDpi" "FALSE"
Option "UseEdidFreqs" "FALSE"
Option "ModeValidation" "NoEdidModes"
EndSection
--------------------------

but am still getting this in the /var/log/Xorg.0.log:
--------------------------
(II) Reloading /usr/lib/xorg/modules/libddc.so
(WW) NVIDIA(0): The user specified HorizSync "29.000-65.220" has been adjusted
(WW) NVIDIA(0): to "30.000-65.220" (the intersection with EDID-specified
(WW) NVIDIA(0): HorizSync "30.000-83.000")
(WW) NVIDIA(0): The user specified VertRefresh "55.000-147.140" has been
(WW) NVIDIA(0): adjusted to "56.000-75.000" (the intersection with

(II) NVIDIA(0): Dell_E228WFP: Using hsync range of 30.00-65.22 kHz
(II) NVIDIA(0): Dell_E228WFP: Using vrefresh range of 56.00-75.00 Hz
-------------------------

What am I doing wrong? how do I disable EDID? Ideas?

Thanks,

have a look at this translation of the german linuxforen.de thread:

nvidia-drivers-1.0.9629 only 800x600

unclecameron · Post by **unclecameron** » Thu May 24, 2007 11:33 pm

I added the suggestions on that link (though it was only partially translated in some places

), and now my xorg.conf looks like this:

-------------------
Option "UseEDID" "False"
Option "UseEdidDpi" "FALSE"
Option "UseEdidFreqs" "FALSE"
Option "ModeValidation" "NoEdidModes"
Option "ModeValidation" "NoMaxPClkCheck"
Option "ModeValidation" "NoEdidMaxPClkCheck"
Option "ModeValidation" "NoVirtualSizeCheck"
-------------------

It still doesn't work on 1680x1050, though it still works on 1280x1024 and 1280x960. I can't think of anything else to check, I compared my gentoo xorg.conf with my CentOS xorg.conf (which works fine on same hardware with slide-in hard drive bay) and the CentOS one is simple, it just loads driver = "nv" and that's it, there's almost nothing else in it's xorg.conf. Ideas? I wonder if I should just buy an ATI card, really the only reason I'm still working on this is in case we find the answer and it helps the next guy

, that would make the effort worth it.

Thanks,
