nvidia-settings only allowing 1440x900 resolution

lumina · 11-09-12, 01:20 AM

For some reason when I try to change the resolution on my laptop display in nvidia-settings on Ubuntu 12.04 I only see one available setting 1440x900. I have no xorg.conf. I used to have a list of available settings. Any thoughts why I would no longer have that. I am using the 304.64 driver. xrandr only lists the one available resolution as well?? Could it be a corrupted EDID? In windows I am able to select various resolutions so I thought perhaps it wasn't an EDID problem. I want to be able to set the resolution of my laptop to that of a projector I am mirroring.
Thanks for any help!!

My understanding is that as of the 302.x releases, if it's a digital flat panel having only one native resolution, then by default that is all you will be offered. There are ways around, documented in the ReadMe for the driver.

Do you know where in the ReadMe file I would find this information. I looked and couldn't find it. I don't understand why Nvidia would have made this change??
Thanks,
Jim

What you need to use to specify other resolutions are MetaModes, but off the top of my head, I can't recall specifically the note that described it, but it bit me too, and was in the first 302.xx release, if my memory serves me correctly. Things have gotten a lot better since then, though, since on 302.17, there wasn't much you could do to work around it - MetaModes were a tad whacked as well . . .

Use the ViewPortOut and ViewPortIn options via the command line:

For instance the line below takes my 1920x1200 display, shrinks to a 1600x1200 pixel area offset by 160 pixels. The viewport in command, transforms the 1600x1200 to a 640x480 equivalent resolution. (Great for playing the original Starcraft).

Code:

nvidia-settings --assign CurrentMetaMode="DFP-0:nvidia-auto-select {ViewPortIn=640x480, ViewPortOut=1600x1200+160+0 }"

If you have dual monitors and want to disable the laptop screen and change the resolution of the external 1920x1200 monitor, use the following:

Code:

nvidia-settings --assign CurrentMetaMode="DFP-1:nvidia-auto-select {ViewPortIn=640x480, ViewPortOut=1600x1200+160+0 }, DFP-0:NULL"
