Error: Could not open /dev/nvidiactl because the permissions

[83mercedes]

Using clean install of Mandrake9:

Every time I reboot, and go to run an openGL game (or glxgears) This error comes up:

 

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.

 

All I need to do to fix this is log-out and login back to X and all is good.

 

OK, so I read the readme from nVIDIA and did the edit of the

/etc/security/console.perms

only to hose up X completely, so I had no screen at all.

So that 'fix' in the readme, I guess, no longer applies.

 

Does anyone have a real solution to this?

Minor problem I know, but one shouldn't have to logout and login again to get this thing to work, agreed?

Thanks in advance.

Here's what I had to do to make the "permissions too restrictive" error go

away,(nVIDIA glx error)on Mandrake 9.

 

I tried commenting out the <dri> line in /etc/security/console.perms and then

doing the chmod 0666 /dev/nvidia* chown root /dev/nvidia*.

 

When I rebooted I got a serious error, and could not get into X or anything

except console.

Then I had to restore the /console.perms file,with the backup I made, rebooted, and everything works

fine now.

 

For some reason, it seems you DON'T have to edit the /console.perms file at all,

just do the chmod 0666 /dev/nvidia* chown root /dev/nvidia*.

 

Maybe one of you senior guys (I mean senior in EXPERIENCE with this sort of

thing) can explain why this is, unless it only works for me, in which case I am

totally without a clue. Come to think about it, I don't have any clue anyway!
