NVIDIA Driver Rendering works only if started with startx

[luiscar2001]

Something pretty strange happens to my fedora 9 installation. I have isntalled the propietary driver from NVIDIA via the LIVNA repository. When booting up and entering the GNOME desktop, the Rendering is not activated.

In order to have ti to activated, I have to:
1. initiate a sesion in text mode. I go to a console and type sudo /sbin/init 3
2. and then startx.

et voilà when I ask the Livna configaration it answers: Direct Rendering: YES.
Nevertheless, if in that mode I ask from the console glxinfo it says Direct Rendering: NO.

Furthermore, if I stop X again (logout) /sbin/init 5, I ask Livna-settigns and answers Direct Rendering: NO

What is it different from init 5 and startx X that prevents the X server of getting Direct Rendering capability?

By the way, I have already changed the permissions of /dev/nvidia* to 666.

Are you actually changing the permissions of /dev/nvidia* to 666 using chmod ?!

The correct way is to add the following section to xorg.conf:

[...]
Section "DRI"
        Mode         0666
EndSection

See if that helps.

I have added the lines in the xorg.conf but still does not work and continues to work when
init 3; startx

What is different from init 5 and startx in relation to the nvidia module?

What do you mean by livna-settings? There is livna-config-display but it doesn't report if you have DRI or not.

What nvidia driver and Xorg version are you running? You can check like this:

rpm -q xorg-x11-server-Xorg xorg-x11-drv-nvidia kmod-nvidia

As well, please attach the /var/log/Xorg.0.log and /etc/X11/xorg.conf files to the thread when starting with "init 5" (this will let us see if the xserver is encountering any errors).

This only works for the ATI driver, as nvidia doesn't use X's DRI module. Even then though, it should work out-of-the-box with the open-source and proprietary versions without the need for those lines.

Ah... I did not know that. OK, now it makes a little more sense - I knew that it should not matter whether it's even specified or not, but....

The version of the packages I am using are

xorg-x11-server-Xorg-1.4.99.902-3.20080612.fc9.i386
xorg-x11-drv-nvidia-173.14.09-1.lvn9.i386
kmod-nvidia-173.14.09-1.lvn9.i686

Xorg.0.log and xorg.conf are attached.

Last, in relation to the livna-config-display, when selecting the subsection OpenGL, it says either if you have Direct Rendering: Yes or No

In my case,
1. When starting with init 5 it says no.
2. When starting with startx, it says yes.
On the other hand, when starting with startx, opening a terminal window and doing
glxinfo
it says Direct Rendering: No
Last, with permission 0600, it would also say no when running with startx.

The programm I am referring to is NVIDIA X Server Configuration which can be found under Applications --> System Tools --> nVidia Display Settings
I atttached two images. One when booting up the system and the second one after making the init 3 and startx as explained.

As you can see under the section OpenGL/GLX Information first it daid Direct Rendering: No and afterwards Direct Rendering: Yes.

Nevertheless, glxinfo continues to report Direct Rendering: No

glx-utils is the package that owns glxinfo and glxgears. I assume that you updated it when you updated the Xorg server and other suff?

Xorg.0.log and xorg.conf are attached.

Baffling. And strange. Never seen this issue before. Hopefully Firewing1 or someone else has....

Good Luck,

just a shot in the dark
in fc8 the livna and nivida gui configure tools are available
check system /Administration /livna display
and see if there is a check in " allow livna-config-display to edit config files"
check it then see if under "automatic configuration" tab make sure that
" disable All " in unchecked and " Aiglx" is checked
and click apply

[luiscar2001]

That did not work. It was already with the settings you mentioned.
