How can I set non-60Hz-Modes?

How can I set non-60Hz-Modes?

[Dexter Filmore]

I used to do that with the nvidia tool on nv, but now I'm a little stuck:
No matter what I do X comes up at 60 Hz. I need to do 50 tho so the attached 
plasma tv doubles it to 100 (at 60 it flickers, plus pulldown problems)

EDID reports a refresh range of 58-62 Hertz which I overrode in xorg.conf.  
When I feed it a custom mode with xrandr --newmode / --addmode it does 50hz 
alright, but I can't make it permanent from xorg.conf.

I tried the Preferred Mode option and "ModeValidation" tho I am not sure the 
latter is nvidia specific.

X log can be found at:
http://www.vaultofsages.de/~dexterf/xorg60hzlog

xorg.conf below.

Can someone have a look and advise, please?

You should be able to use cvt to generate the modeline you need.  Then
you can use xrandr --newmode to add it, xrandr --addmode to associate it
with the appropriate output, and then use xrandr to set the mode.

I've successfully used this technique when my laptop is connected to a
projector through a long VGA cable (and possible a switch/splitter) that
prevents it from reading the EDID info.

That's what I do now. Thing is, the same TV provided EDID to an nvidia before 
and there I could use the settings tool to tweak these things.
I'd like the machien to go 50Hz at login tho. 
I can tinker a script, but this just does not seem to be working as supposed.

I've learned that overriding detected values is discouraged. The 
prefered solution would be to alter the EDID data in your display 
harwdare or insert a special EDID sending device in the monitor cable.

Configuration of software is not done through conf files anymore, it is 
done using hardware. If autodetection gives values you do not want, you 
have to alter the hardware.

The reason for this policy is, if someone succeeds in solving some issue 
using altered conf files, he might post this solution to the internet, 
where someone else might find and try it. In certain cases this could 
even damage hardware.

So it looks like it's safer to leave the user with a hardware that does 
not run due to lacking setting options than giving the user the 
possibility to damage his hardware using wrong settings.

I can't imagine people trying to configure multihead without .conf files. 
How's that supposed to work?

I've been exaggerating a bit, I must confess... But, to keep things 
straight, I really did multihead setup using xrandr in a startup script.

You think mere mortals are going to find startup scripts, not to mention 
xrandr, easier to figure out than config files? Plus, in my experience, there 
are far too many different script file names and locations among various 
distros than X config files and locations. Not to say .config file setup is 
easy, because it's not, but to me they're the lesser evil.

No. I described this situation because it annoys me. I do not like it at 
all. Nevertheless I have to cope with it in some way as I can't modify 
the drivers.

I thought of "X without config file" as a bad idea from day one - and each 
time I have to do something that is based on something not properly reported 
by hardware or not properly auto-detected by X it so totally proves me right.

Face it, neither are hardware manufacturers capable of adhering to their 
standards nor is X capable of reading my mind.

I've always found the Debian XRandR documentation to be good.  Check it
out: http://wiki.debian.org/XStrikeForce/HowToRandR12

Apart from all the nvidia-specific options you've got there, you're
missing...

You may have noticed from your Xorg.0.log that your monitor section
*was* getting read, and the preferred mode *was* getting applied; just
to your VGA output.  If you associate your Monitor section with the
output you want it to apply to, it should work.

Figured that meanwhile, too. Still comes up at 60. Beats me. I wrote a little 
script for mplayer to register and set modes depending on the video so that 
works for me.

Actually I got bigger problems like xv not properly working... and vmware not 
working on the .39+ kernels intel needs... and debian testing being the only 
dist with at leat 2.15 and otherwise being a total bitch about almost 
anything.. and me not getting mplayer to apply the compressor plugins for 
dts... 
Actually, right now about *all* these problems could be solved by moving the 
machine to Win7.

Are you sure? Is it possible only HDMI-1 works at 120, and the others at 60? 
Did you try plugging into any other HDMI ports? Is there a VGA port to try?

There's pretty much one HDMI output on that board, one DVI, one VGA.
And why 120? Who would want 120?

Christopher James Halse Rogers replied to add 'Option "Monitor-HDMI2" 
"Monitor0"', making me think there actually was a #2 HDMI port.

> And why 120? Who would want 120?

That was an error. I meant to type 100 as a consequence of your plasma's 50 
doubling, not the 120 that many panel TVs offer.

How exactly did you try to override VertRefresh? I would have tried something 
like

	VertRefresh 24-51

and if that didn't work, also adding

     Option	"TargetRefreshRate"	"60"

and/or

     Option	"DDC"	"off"

and/or

     Option	"DefaultModes"	"on"

and/or deleting your explicit modelines, allowing the built in modeline 
generator to do its job.
