Xorg.conf multiple monitors different refresh rates

jeremy5561 · 2015-05-17 18:49:40

I have two monitors on my setup, with my primary montor being to the right of my secondary. They both have resolution 1920x1080. I'm trying to get my primary monitor to run at 120 Hz but it's only doing 60. My secondary monitor is a different model that can only do 60 Hz.

This is my xorg.conf

This is actually one of the first times i've had to go under the hood linux (I've recently been using a linux computer at work) so I'm pretty newbie - any help would be greatly appreciated.

try using xrandr

xrandr --output <your monitor> -s <your resolution> -r <your refresh>

For More info about xrandr https://wiki.archlinux.org/index.php/Xrandr

jeremy5561 · 2015-05-17 21:07:47

nothing happens after running
xrandr --output DVI-I-1 -s 1920x1080 -r 119.98

Malkymder · 2015-05-17 21:10:20

look in your /var/log/Xorg.0.log file to see if any errors

Malkymder · 2015-05-17 21:12:47

Also check the current refresh rate using

xrandr -q

an asterisk should be beside the current refresh rate in use

I don't think using

xrandr --output (output) -r 119.98

is the right way of doing it. When I type this command, nothing happens (no reply from terminal)

But when I type

xrandr -r 119.98

I get

 Rate 119.98 Hz not available for this size

Malkymder · 2015-05-17 21:30:41

you have 2 monitors ergo you need to specify what monitor your asking the changes otherwise it uses the default monitor withch in your case seems to be DVD-D-0

Malkymder · 2015-05-17 21:44:59

try adding this to your screen section in the xorg.conf

	Option "UseEDIDFreqs" "False"
	SubSection "Display"
		Modes		"1980x1080_119.98" "19280x1080_60"
	EndSubSection

When you open the nvidia-settings tool does it now allow you to select the higher resolution

jeremy5561 · 2015-05-18 14:13:45

Unfortunately not .

Malkymder · 2015-05-18 17:54:27

Select the 1920x1080 resolution instead of auto that will let you specify a refresh rate**

Oddly, the settings don't commit after a restart.

After settings the refresh rate in nvidia-settings, if I close the panel and reopen, the settings are still there.

However after a full restart the settings are lost. The resolution goes back to auto. My xorg.conf file is kept though.

Malkymder · 2015-05-19 02:33:47

if your using gnome shell it calls xrandr on start and overrides whatever you have in your xorg.conf

You could use a bash script to run on login to reapply your values .... many posts available on how to do that in the forums
