Dual monitor hotplugging/refresh rate

[kombucha]

I'm using nvidia's proprietary driver with my nvidia card... I have an LCD monitor in addition to my laptop's screen... I want to make it such that when the external monitor is plugged in, Fedora uses only that one, and when it isn't, Fedora uses the laptop one. I think it might be trying to do this now, because it's almost working, except Fedora picks a default refresh rate that doesn't work with my external monitor, and all I can see is "Input Not Supported". When I unplug the monitor, reboot, plug it in and configure it manually, it works fine at 1680x1050 at 60hz.

So essentially I just need to know how to make 60hz the default for my external monitor. :)

*bump* :P Anyone?

[FNHi]

I had the same problem and I fix it.

You must take work with your xorg.conf
# vi /etc/X11/xorg.conf
I'll show you my xorg.conf before and after fix.
Only my card is radeon. For configuring xorg.conf I was read my
# man radeon
You must do the same but with your video card manual.

# less /etc/X11/xorg.conf
before fix
# Xorg configuration created by pyxf86config

How you can see, I added some lines in xorg.conf for my both monitors and for appearing one big desktop.
Your work must be done in :

Section "Screen"
Identifier "Screen1"

Section "Device"
Identifier "Videocard1"

Section "Screen"
Identifier "Screen0"


Section "Device"
Identifier "Videocard0"

Section "Monitor"
Identifier "Monitor1"

Section "Monitor"
Identifier "Monitor0"

Section "ServerLayout"
Identifier "Multihead layout"

Go here for generate your monitor settings.
http://www.sh.nu/nvidia/gtf.php

Put this for example: 1024х768 с 60Hz and you get this line for you monitor:

# 1024x768 @ 60.00 Hz (GTF) hsync: 47.70 kHz; pclk: 64.11 MHz
Modeline "1024x768_60.00" 64.11 1024 1080 1184 1344 768 769 772 795 -HSync +Vsync




Put this line in your xorg.conf file in Section "Monitor"




Another page for generate modelines

But I generated my modelines with first one.
