Hi everyone,

I'm not sure where I should be posting this, but I think the Nvidia Guide is missing a pretty important section for nvidia-settings/nvidia-xconfig:
http://www.gentoo.org/doc/en/nvidia-guide.xml

I'm never able to get a DE working without it. Shouldn't it be included?

Well that's pretty strange as I've always been able to get my nVidia cards working without using those. What is it that you have to do with them?

Honestly, nothing exciting. Just download nvidia-settings and run nvidia-xconfig in addition to everything else in the 'doc. After that, X works.

If I *don't* run that, I get the generic unable to open display/screen(s) found, but none have a usable config etc

Creating minimal xorg.conf works here
Code:
Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
EndSection


Running nvidia-xconfig is discouraged because it creates mostly useless xorg.conf.

*shrug* I tried that as well...It may have to do with using multiple monitors, I'm not sure.

Anyways, if it's discouraged, that's fine. Ignore me :)

Using multiple monitors certainly needs more complicated xorg.conf. Probably nvidia-xconfig can create a draft for this. Shouldn't be used as an actual conf, though.
We will not ignore anybody, these forums here are for sharing knowledge. Your input is valued. :)

Not really, as it also adds tons of cruft that may or may not be harmless. A fully working, non-crufty multi-monitor config looks like this:
Code:
Section "Device"
    Identifier  "Nvidia card"
    Driver      "nvidia"
    Option      "TwinView" "on"
    Option      "TwinViewXineramaInfoOrder" "DFP-0, DFP-1"
    Option      "TwinViewOrientation"       "DFP-1 RightOf DFP-0"
EndSection

Adjust output names accordingly of course.

What I'm not sure about is what happens with the 300 driver series (302.17 and 304.22 currently). I think the above still works, but those drivers support xrandr1.2, so the xrandr way of configuring should in theory work too:
Code:
Section "Device"
    Identifier  "Nvidia card"
    Driver      "nvidia"
EndSection

Section "Monitor"
    Identifier  "DVI-0"
    Option      "Primary"  "true"
EndSection

Section "Monitor"
    Identifier  "DVI-1"
    Option      "RightOf"  "DVI-0"
EndSection

Just run xrandr on the commandline to get the output names.

Hope you mean "emerge" instead of "download". :wink:
