Can't select 1920x1080 (monitor's native res)

epsilon72 · 03-19-2007, 03:42 PM

I installed kubuntu last night and was able to install the nvidia drivers successfully through automatix a little bit ago.

Before I installed the drivers, I had xorg.conf modified to let me use 1920x1080 for my resolution. Now that the drivers are installed, from what xorg.conf looks like 1080p should be selectable, but it's not...

I don't know what the problem is at all...I'm using an EVGA 7800GTX with a Westinghouse LVM-42w2 display. I definitely know the card is capable of 1080p, I've been running Windows at that res for a long time, as well as SUSE for 1 week.

The file is virtually identical to what it was before the nvidia drivers, except for the "device" portion.

Does the nvidia driver you installed capable of that resolution?
I would make sure you have the latest drivers.

Automatix installed it for me - could automatix be out of date?

When I switch the driver back to "nv" - the resolution works fine, but I'd rather be using the nvidia driver if possible.

I think I might try this method instead.

Brian1 · 03-19-2007, 04:19 PM

Never heard of automatrix so no idea what it is.

Automatix is a graphical installer for debian distros - http://www.getautomatix.com/]

epsilon72 · 03-19-2007, 05:23 PM

This is ridiculous - the nvidia driver doesn't even support 1080p!!! I've reinstalled it twice now only to get the 1280x1024 max resolution limit...

I was considering FC6 as well as kubuntu - maybe I'll have more luck with that one.

Actually, I probably won't - it's probably not the distro's fault - for some reason nvidia must think no one who has a 1080p display uses linux...how ridiculous...

I suggest to try installing the nvidia-glx package that is in the Ubuntu repositories. Automatix is not a standard part of the Ubuntu release and I'm not sure what its doing or what it installed for you. IMHO It's best to start with packages in the Ubuntu repositories before looking elsewhere. Refresh rate for LCD displays isn't an issue to prevent flicker so you can let it default to what in all likely hood will be 60 anyway.

The second two times I didn't use automatix - I ran the install straight from the terminal (no x server) with the driver downloaded directly from nvidia's website.

The driver is working because I have my xorg.conf device section set to the "nvidia" driver (not nv) - it just appears that nvidia thinks that no linux users own 1080p panels. If it's the driver's fault I'll have to go back to Windoze until nvidia decides to provide support for my hardware..

I forgot to mention that with the initial kubuntu driver, I can get 1920x1080 but the gamma is totally off - it makes photos/pictures look terrible, and the window for gamma settings is 'broken' (probably due to the fact that I had to add the 1920x1080_60.00 modeline to xorg.conf).

taken from the /var/log/ xorg file -

Code:

(WW) NVIDIA(0): No valid modes for "1920x1080_60.00"; removing.

epsilon72 · 03-19-2007, 05:56 PM

Back to windoze it is.

Brian1 · 03-19-2007, 06:05 PM

Don't give up yet. Have you check the nvidia forum?
Might search there for your issue or ask the question there.
I browsed it a bit and one seems to mention downgrading one version for a resolution issue. Not quite like yours but you might give that a try.

I could try downgrading - I just assumed that with 1080p not being fully "accepted" yet in general, I would have even less luck with older drivers. I'll do that now - *begins switching to december '06 drivers*

epsilon72 · 03-19-2007, 06:22 PM

Big surprise, december drivers don't work either. (losing patience)

Downgrading further.

epsilon72 · 03-19-2007, 06:31 PM

Drivers as far back as October don't work.

Moving to nvidia forums...if that fails, I'm switching to Zod, to see if I have better luck with that one.

epsilon72 · 03-19-2007, 10:34 PM

Finally. Found a decent guide here. There's a lot of misinformation floating around (not here though) that screwed me up.

If anyone is having problems configuring nvidia drivers, point them to the site above.
