After using Fedora for about two weeks, I found that this was the best way to install the NVIDIA driver. I guess I was lucky that this kernel wasn't a debug one (or is it?; I missed this point) because it kind of worked.
I ran the instructions for F16 (first post) for akmod-nvidia, rebooted, got a progress bar then when it was to load X the bar flicked about four times and nothing.
Then I had an inspiration to run nvidia-xconfig, rebooted and X loaded.
The problem is that I don't have GLX.
First particularity is that a while ago, while testing if the sgfxi script would work in Fedora, this script created an xorg.conf file. While using nouveau this file actually didn't interfere (as nouveau doesn't use it, I think) but I'm mentioning it because I don't know if this interfered when I installed the NVIDIA package.
/etc/X11/nvidia-xorg.conf is very small:
Code:
# RPM Fusion - nvidia-xorg.conf
#
Section "Device"
Identifier "Videocard0"
Driver "nvidia"
EndSection
(proper xorg.conf created by nvidia-xconfig has normal size)
/etc/X11/xorg.conf.d/00-nvidia.conf
Code:
#This file is provided by xorg-x11-drv-nvidia
#Do not edit
Section "Files"
ModulePath "/usr/lib/xorg/modules/extensions/nvidia"
ModulePath "/usr/lib/xorg/modules"
EndSection
I'm thinking if maybe the system is just having trouble with finding the alternate path for libglx because ever since I installed Fedora it always fails to find/auto-complete executables in /usr/local/bin for instance (it actually finds them but I have to open different shell sessions, sometimes more than once until it 'gets it').
Here's the general info:
Code:

The error in Xorg0.log is:
Code:

---------- Post added at 11:47 PM ---------- Previous post was at 10:06 PM ----------
I see that xorg-X11-nvidia-libs installs the libs in /usr/lib/nvidia but it keeps the libs from mesa-libGL in /usr/lib/libGL.so.1*
Maybe it's this that's conflicting?
I'll rename the ones from mesa-libGL to test.
---------- Post added at 11:57 PM ---------- Previous post was at 11:47 PM ----------
Leigh, I renamed /usr/lib/xorg/modules/extensions/libglx.so and linked the one from nvidia to its place and also renamed /usr/lib/LibGL.so.1* and linked the one from nvidia to /usr/lib/LibGL.so.1 and now GLX is working.
I'll try it out but I suspect the latter is the one that was conflicting so if it's the case then xorg-X11-nvidia-libs should rename the mesa-libGL libs and then restore in case of un-installation. |
If you think there is a issue file it here
https://bugzilla.rpmfusion.org/

Re: F16,F15 & F14 Nvidia driver guides
I thought about it but since every time xorg-X11-server-Xorg or mesa-libGL are updated they'll probably restore the conflicting libraries maybe the best would be just to update the how-to.

Re: F16,F15 & F14 Nvidia driver guides
I tried this under Scientific Linux and it caused the boot process to hang, forcing me to do a ctrl-alt-F2 to get a terminal prompt so I could uninstall akmod-nvidia. If I have a problem this time as well, can I do the same thing to restore back to the way it was? Just uninstall akmod-nvidia?

Re: F16,F15 & F14 Nvidia driver guides
Where are you installing it now?
I don't think that the boot would hang normally by doing what's described in the how-to. You may end up without X (video driver) like I did and I just needed to run nvidia-xconfig and reboot.

I haven't installed it yet, but it would be on the same system as I had Scientific Linux 6.2 installed....a Dell XPS laptop.

I don't think so, Yellowman. There's no 'ModulePath' in the generated xorg.conf.
From xorg-conf generated with nvidia-xconfig:
Code:
Section "Files"
FontPath "/usr/share/fonts/default/Type1"
EndSection
From /etc/X11/xorg.conf.d/00-nvidia.conf:
Code:

Leigh states in the linked bug report that having a empty files section (no module paths) in xorg.conf overrides the paths set in /etc/X11/xorg.conf.d/00-nvidia.conf

Re: F16,F15 & F14 Nvidia driver guides
(-edit as you posted while I was writing- It doesn't override. Maybe if it hadn't anything there then X wouldn't use /usr/lib/xorg/modules/extensions/ as a path, but I'm not sure about that)
And, BTW, the module paths from the rpmfusion package work fine (but /usr/lib/xorg/modules/extensions/libglx.so has to be renamed because it's in the default X module path).
On another issue, do you know if it's a bug that the package installs 00-nvidia.conf as we have also a 00-system-setup-keyboard.conf? I mean, shouldn't the xx-nvidia.conf be something else than 00?
(the keyboard works fine for me as the nvidia-xconfig generated xorg.conf includes the keyboard info but I don't know if it would still work with the nvidia-xorg.conf file from the package which has only the video driver info, just thinking about it)
---------- Post added at 06:01 PM ---------- Previous post was at 05:55 PM ----------
But I may test later by commenting the "Files" section in xorg.conf (or using the nvidia-xorg.conf provided by the package) and re-enabling libglx.so from Xorg to see if it works (that is, to see if X will skip /usr/lib/xorg/modules/extensions/).

You're wrong about the override.
as for the 00- files, it doesn't matter as it takes the whole file name into account.

Re: F16,F15 & F14 Nvidia driver guides
This tidbit here is keeping me from trying this on my Dell XPS laptop: "Optimus graphics will not work if means to disable the integrated graphics in hardware are not available." My video adapter is a hybrid Intel/Nvidia. The Nvidia is GT 540M with Optimus. There is no way to disable Optimus in my laptop's BIOS.

Re: F16,F15 & F14 Nvidia driver guides
I made tests.
Indeed, if xorg.conf doesn't have a "Files" section, there's no need to rename anything and GLX will work.
But /etc/X11/nvidia-xorg.conf alone doesn't do anything. X doesn't see it and it falls back to vesa.
And using nvidia-xorg.conf as xorg.conf, as simple as it is (only the "Device" section with the video card and driver), works fine.
And I get now that any custom thing (except the video driver?) we want to add we add to /etc/X11/xorg.conf.d/00-nvidia.conf.
All tests I made by switching from init 3 to init 5 and back.
So, unless I'm still missing something, shouldn't the package install xorg.conf instead of nvidia-xorg.conf? Or better still, add the "Devices" section in /etc/X11/xorg.conf.d/00-nvidia.conf?
I'll do one more test to confirm this by renaming back xorg.conf to nvidia-xorg.conf and rebooting to see if X sees it then or not (but from the Arch wiki, it shouldn't. Again from the wiki, putting the video driver in xorg.conf.d/00-nvidia.conf should).

Re: F16,F15 & F14 Nvidia driver guides
Looks perfect (I'm no scripter myself), but I don't remember to have an /etc/X11/xorg.conf.xorg-x11-drv-nvidia_uninstalled (but I'm not really sure if I removed my previous xorg.conf prior to installing the package).
So, all-in-all, it seems everything is covered. For some reason it failed for me when I first installed it.
Just to be sure, when we have another upgrade (I have already upgraded to 295.40), I'll make before some custom xorg.conf to check if the package is moving it out of the way as it should.

===========================
I have implemented the section:-
Section "Device"
Identifier "Videocard0"
Driver "nvidia"
Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection
This seems to be great for other people.
The change for the brightness seems to be set but is only activated after next reboot ?
- I have seen this on the Hardware forum but that seemed to be going down a different route.
Any advice ?
