[Solved] Nvidia-settings auto set 1680x1050 when should 1920

[mattyd.24]

Hi all,

So I recently bought a new 24" 1920x1080 monitor (BenQ G2420HD).
I regularly unplug it from PC (DVI connection) and take it to the Xbox360 and plug it in there (VGA connection) so I can game in Full HD [All possibly unrelated].
I noticed that after restarting it will always be set to 1680x1050, when it should be 1920x1080. I've tried fiddling with Nvidia-settings as root, saving settings to Xorg config file and fiddling with the Xorg config file manually, but no matter what I save it always ignores this and reverts back to 1680x1050.

Of course, I've Googled and searched forums, but as usual my problem seems to be unique.

Running Linux Mint 8 Main.

Any help would be much appreciated; I don't want to have to change my resolution/move screenlets every time I boot!

EDIT: Also, not sure if this is 'Hardware' or 'Software' related so sorry if it's in the wrong section.

Welcome To Linux Mint
I think that you may check your refresh rate & see if it is not maxed out, that may be the cause,
& if you make a change , I think you have to be Root. Reboot after change.
It could also be that your monitor had a default also, but it seems unlikely.
I hope this helps, Have a Good Day.

Welcome To Linux Mint

Thanks
Although I've been using it for quite some time, I've thankfully had few problems with it, why I've not posted often.

Nvidia-settings has refresh rate set to Auto, the only other option being 60Hz. xorg.conf has:
HorizSync 24.0 - 83.0
VertRefresh 50.0 - 76.0
Does this seem too high? I don't know what the max is.

As I said, "I've tried fiddling with Nvidia-settings as root", then rebooted after and no change.

I just checked and found no menu option for a default resolution. The 'Information' section of the menu says it is currently 1920x1080 (true, I changed it again after booting) and Refresh Rate is 60Hz

Thanks for your reply!

I would think, this is important information/data to include when considering the system as a whole..
The monitors native resolution, usually the max rate, has been given, but..
--you haven't mentioned the Nvidia card you are using, so it is a guess as to why, the resolution won't stick for you

The fact that you are using a DVI connection does not guarantee, perfect settings or setups..

In terminal, check

• inxi -F

--might provide some light on the system as built.

Sorry, forgot that would be relevant. I'm using a Nvidia GeForce 8200, integrated with my Asus M3N78 Mobo.

I know using DVI doesn't guarantee perfection, but I assumed if I told the system exactly what resolution to use it would remember it

Does anyone else have any ideas...?

Solved after a lot of Googling.
Finally found this:

In particular:

Jaunty uses the settings in "/etc/X11/xorg.conf" to configure the display resolution at Ubuntu startup. "xorg.conf" settings are written by "nvidia-settings".

Jaunty uses the settings in "/home/username/.config/monitors.xml" to reset the display resolution (when you log into your user). The settings in ".config/monitors.xml" are written by "gnome-display-properties".

1. The values in ".config/monitors.xml" are not automatically synchronized when "nvidia-settings" is used to change the display resolution, so it is necessary to update those values by running "gnome-display-properties" (System->Preferences->Display).

2. In my case (I have a nvidia FX-5200) "gnome-display-properties" is not detecting correctly the "Refresh Rate" parameter, so I manually updated the ".config/monitors.xml" file ("rate" parameter) with the correct value.

Edited my ".config/monitors.xml" which had almost no information, and had the resolution set to 1680x1050. Now everything works fine!

Thanks for showing us how you solved it. That is very useful information.

(Especially to KDE types like myself who rarely venture into the Gnome world)

cheers

No problem!
Hopefully others see this too as the problem seems fairly common.
