Nvidia + XFree86 4.1.0.1 + iiyama VMPro 410 horizontal refresh probs

Dear All,
I'm using Debian 3 and have installed the 2190 nv drivers - they seem to be working fine apart from one problem: when I first get into X my display is all garbled - for some reason it is trying to run at 30.4 KHz horizontal refresh rather than the prescribed 91.2. Then when I exit the session and start another one it is fine and uses the values I told it to in my config (see below).

I didn't have this problem when I was using the built in "nv" driver (before I installed nvidia's own driver) and I am sure the values in my config below work (they are working fine now after I restarted the session, and work fine in windows). I'm also sure that the config below is being read correctly (have checked /var/log/XFree86.0.log).

So do the nvidia drivers use some other config for the first session? I've not found *anyone* else who's had this problem, it's got me stumped

Cheers for any help you can give,
--
Will

You need to give up a hsync and a vsync range and not a single number.

Yes that is what I had originally - didn't work - I put in a single value (that which worked for windows) to try to force it to use that (it still doesn't)

Take a look at your XFree log file and see what it has to say, compare the first startup that doesn't work to the second that does. Maybe some insight there.

Or perhaps you should make yourself a custom modeline? http://koala.ilog.fr/cgi-bin/nph-colas-modelines fun stuff.

That was one of the first things I tried - I made a copy of the log when the display was garbled... exited the session - examined the log - hadn't changed i.e. it was still running the same x process I assume.

I didn't see your xfree86 log file but it can be that there were some errors in it related to resolution validation. Really put in that hsync/vsync ranges again. You can't force the drivers to those fixed frequencies since most resolutions can't use those values. (they are out of range for example ..)

Then add a line like this: Option "IgnoreEdid" to your screen or device section perhaps this helps.

There REALLY shouldn't be any problem forcing EXACTLY what you need to when you use modelines... I personally run multiple fixed frequency monitors but i give them enough range to use the modelines i have written.... if you give it a really wide range, you can use xvidtune to tweak the values
