Dernier Pilote Nvidia

Bonjour,

je viens d'upgrader mon pilote Nvidia vers la version 61xx et je rencontre des problemes que j'avais pas avant : OpenGL marche plus et ma carte son est bloquée. J' ai alors suivi les instructions données par Nvidia et tout fonctionne normalement à présent :


" It is likely that a security module for the PAM system may be
changing the permissions on the NVIDIA device files. In most cases
this security system works, but it can get confused. To correct this
problem it is recommended that you disable this security feature.
Different Linux distributions have different files to control this;
please consult with your distributor for the correct method of
disabling this security feature. As an example, if your system has
the file
/etc/security/console.perms
then you should edit the file and remove the line that starts with
"<dri>" (we have also received reports that additional references to
<dri> in console.perms must be removed, but this has not been verified
by NVIDIA). If instead your system has the file
/etc/logindevperms
then you should edit the file and remove the line that lists
/dev/nvidiactl. The above steps will prevent the PAM security system
from modifying the permissions on the NVIDIA device files. Next,
you will need to reset the permissions on the device files back
to their original permissions and owner. You can do that with the
following commands:
chmod 0666 /dev/nvidia* chown root /dev/nvidia* "


Pär contre, étant débutant je n' ai rien compris à ce que j'ai fait, je ne sais meme pas ce qu'est "PAM security system".
Quelqu' un peut il m'expliquer car j'aimerai comprendre comment mon systeme fonctionne.

Merci pour votre aide.
