Nvidia e permessi

[sunreal]

Mi è successo recemente, e devo dire solo con un paio di giochini, che non riesco ad avviarli, se non da root, e ricevo questo messaggio quando li avvio da user:

Visual Properties Report
------------------------
Compatibility mode, properties unknown.
Error: Could not open /dev/nvidiactl because the permissions
are too resticitive. Please see the FREQUENTLY ASKED QUESTIONS
section of /usr/share/doc/NVIDIA_GLX-1.0/README for steps
to correct.
/usr/bin/torcs: line 53: 5743 Segmentation fault $LIBDIR/torcs-bin -l $LOCAL_CONF -L $LIBDIR -D $DATADIR $*

Allora vado a leggere le FREQUENTLY ASKED QUESTIONS come cosigliato e leggo:

Q: OpenGL applications exit with the following error message:

Error: Could not open /dev/nvidiactl because the permissions
are too restrictive. Please see the FREQUENTLY ASKED QUESTIONS

A: 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 QUESTO FILE NON ESISTE
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 NEANCHE QUESTO ESISTE
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*
QUESTO ULTIMO COMANDO MI DA QUESTO OUTPUT

chmod: impossibile accedere a `chown': No such file or directory
chmod: impossibile accedere a `root': No such file or directory

Cosa debbo fare?

AH! Dimenticavo uso slack 10.1 - kernel 2.6.10 - driver nvidia 7167

Ma sei sicuro che non sono due comandi separati? mumble muble

Codice: Seleziona tutto

chmod 0666 /dev/nvidia* 
chown root /dev/nvidia*
