driver ignores all modes greater 1024x768

[Dilandau]

i had 1280x1024 with annother linux and a three year old driver on the same hardware. now it was impossible. even after adding some modelines it was still impossible. all i get is 1024x768.

here are my specs:

amd duron stalebred 1600 - elsa gladiac 311 (geforxe2 MX, nvidia) - elitegroup k7s5a (sis, lan) - 256mb ram - wintv pci fm - ide cdwriter - hp psc 1110

gentoo 2004.3

media-video/nvidia-kernel-1.0.6111-r3

bash-2.05b# cat /proc/driver/nvidia/cards/0
Model: GeForce2 MX 100/200
IRQ: 5
Video BIOS: 03.11.01.30.19
Card Type: AGP


NOTE: i get the same result, that the max size is just 1024x768, with the special "IgnoreEDID" option in the device section, regardless if that option is present or not. just the logfile looks a bit different. i upload the logfile as it looks without that option present as the second attachment.


by the way, against your claims the forum still rejects .log and .conf extensions.

IgnoreEDID, horizsyn and vertrefresh won't do squat if you haven't specified a resolution above 1024x768. Neither will it do any good if you have specified higher resolutions in the 16-bit and 8-bit section.

i set the res back to 1024x768 so that i can work well with the computer. the desired mode and the problem i report concnerns any greater resolutions though. the logfiles should tell enough.

[Dilandau]

this problem is still unsolved. please pay attention.

The send the config files from when you try and use above 1024x768. It's hard to see a problem with config files that are edited to work.

[Dilandau]

its just the "1200x900" added to the res line at 24 bpl when/what not works. the output you then get is in log.txt already.

Make sure the horizontal/vertical frequency ranges match those of your monitor and comment out the ModeLine entries (unless you're positive they're valid). The mode validation performed by the NVIDIA driver is described in detail in the README.

[Lithorus]

Yeah, modelines shouldn't really be necessary unless you need some really specific resolution, which you can compile yourself with gtf.

[Dilandau]

where to get gtf? whats it? no such package in gentoo. i used the mode generator script from http://koala.ilog.fr/cgi-bin/nph-colas-modelines to get the lines i show. according to that script (i entered exactly my monitors values correctly) a very good resolution and refresh rate should be possible.

i changed my settings a bit, so now they read:

Modes "1600x1200" "1400x1050" "1280x1024" "1024x768" "800x600" "640x480"

The highest mode works!!! And it does so with 75 Mhz. For some reason one of the two next smaller modes, i cant figure out which one, refuses to work. 1024x768 works as known it works and the two most small modes also work. So some modes between 1600x1200 and 1024x768 dont work, but they should (and more than just one variant) and they worked before with annother os! i see in teh logs that some mode shave been voided but for what reason? must be a detection error ... setting the IgnoreDDT flag to true changes what the log says (see first posting of this thread) but the resulting modes that i can switch to remain the same. Also my monitor says it can do 210 Mhz total and this is reported correctly by the log and thats far enough in any case i wanted. Even what the manual says, that the monitor can do max 202 mhz, was enough. It can be an error in the driver.

i attach log and this full config for exactly this setting (again) for convenience.

Maybe you missed the " in the

"1200x900

Gtf is a command which should be availible when you have installed X.

You should try with the "1280x960" which is the correct 4:3 resolution.

Either way all those modelines is really unnecassary.

[Dilandau]

it turned out that 1280x1024 is the only intermediate resolution that works. this must be an error or setting elsewhere?

(**) NVIDIA(0): Default mode "1600x1200": 202.5 MHz, 93.8 kHz, 75.0 Hz
(**) NVIDIA(0): Default mode "1280x1024": 157.5 MHz, 91.1 kHz, 85.0 Hz


The working modes are default modes; take out the ModeLine entries or replace them with valid GTF entries (http://www.sh.nu/nvidia/gtf.php).
