Hi Jose,

Was this discussion at this link you posted yesterday on a problem with the cheese program also related to this issue?

• Are you using SELinux? If so, temporarily shut it off and invoke cheese again just to see if it works (and turn SELinux back on:

[root@yoursystem ~]# getenforce;setenforce 0;getenforce
[root@yoursystem ~]# echo "next invoke the cheese program and make note of differences in logs and function"

• See if you can acquire some clues from your log files.
  Go to /var/log/ and look for the most recently written to log files:

[root@yoursystem ~]# cd /var/log
[root@yoursystem ~]# ls -ltr

I suspect Xorg.0.log 'might' give some clues, but do a tail -f of the affected logs to watch the errors as you attempt to activate the 'cheese' program.

Also, (you probably have), did you verify the proper nvidia linux driver?

[root@yoursystem ~]# tail -f NAMEOFLOG

Note, you can do a 'tail -f' of more than one log (tail -f messages Xorg.0.log) for example.

So while you are performing the 'tail -f' of the affected log(s), run the cheese program and note the errors in the log.

Alternatively, you can place a trouble case in with Red Hat - they will likely want an sosreport attached.

Good luck
