Question Troubles with Nvidia permissions


Hi there,
I have some troubles with Nvidia permissions, when I try for exemple to see a 3D screensaver it gets me that:

------------------------
Error: Could not open /dev/nvidiactl because the permissions
are too restrictive. Please see the FREQUENTLY ASKED QUESTIONS
section of /usr/share/doc/NVIDIA_GLX-1.0/README for steps
to correct.
------------------------

I readed it, it says that's something about PAM security modules (I have dropline gnome installed), to fix it "<dri>" line from "/etc/security/console.perms" must be removed, permissions must be changed to "chmod 0666 /dev/nvidia*" and "chown root /dev/nvidia*" ...

Ok, first, I have "crud" user added to "video" group (#gpasswd -a crud video)

-----------------------
$ id
uid=1000(crud) gid=100(users) groups=17(audio),18(video),100(users),102(clamav)
-----------------------

Then why nvidia doesn't work with default modes

crw-rw---- 1 root video 195, 0 2005-05-26 15:14 nvidia0
crw-rw---- 1 root video 195, 1 2005-05-26 15:14 nvidia1
crw-rw---- 1 root video 195, 255 2005-05-26 15:14 nvidiactl

and with

crw-rw-rw- 1 root video 195, 0 2005-05-26 15:14 nvidia0
crw-rw-rw- 1 root video 195, 1 2005-05-26 15:14 nvidia1
crw-rw-rw- 1 root video 195, 255 2005-05-26 15:14 nvidiactl

works ?!

Anyways I think that's UDEV who gives permissions to nvidia devices... But that's not the problem... The problem is that I have "video" group added to "crud" user and it doesn't work !! Really I don't understand

Any suggestions will be greatly appreciated.

Greets,

C-

It says to put permissions "chmod 0666" to nvidia devices from udev permissions configuration file... Why have I to do that if Nvidia devices belong to 'video' group and my 'crud' user is added to 'video' group ? ..

Greets,

C-

Did you logout and re-login after your change ?
