nvclock need no root

[Maduser]

nvclock run in the under a normal user without sudo.
I think on a this can be doungerous, f.e. if it is need to underclock the gpu on a multiusers System.
A change of gpu clock can make a damage to hardware, so only root should be able to do this.

Can this not also be restriced by changing the permissions of /dev/nvidia* ?

I think there is not much security gained if nclock can be run only by root but the device to speak directly to the nvidia hardware has still write-permission for all users.

I confirm it at Feisty.. still can run it as normal user.

[Daniel T Chen (crimsun)]

Anyone in the video group has permissions to alter.

Andreas Simon, Marco Rodrigues, Daniel T Chen I think that users needed the permissions for change the backlight, it only work with nvclock with a lot of graphic cards, see it on:
