xscreensaver issues

Hi, when I try to activate a screensaver that uses OpenGL, it shows a message that indicates that I have not the necessary permissions to execute it.
/dev/nvidia0 and /dev/nvidiactl are the problem ... when I change the permissions to 0666 on both everything is fine, but when I reboot, it's all the same problem.

I have to modify something here? /etc/udev/permissions.d/udev.permissions  ... "nvidia" is set to 0666:

nvidia*:root:users:0666

Also, I belong to the "video" group

Thanxs

Re: xscreensaver issues

2 options:

1. remove suid on /usr/bin/xscreensaver

2. or add
KERNEL="nvidia*", GROUP="video", MODE"0666"
to /etc/udev/rules.d/00.rules

Re: xscreensaver issues

Thanks mico that worked.

By the way, I'm using ArchLinux 0.7 and the file is actually:
/etc/udev/rules.d/udev.rules

Re: xscreensaver issues

OK - mico is suggesting using a custom rules file - .rules are read alphabetically so prefixing one with 00 guarantees it is read first

Meshuggin - udev.permissions is no longer used - permissions are now set in .rules files

The latest version of udev has some upstream changes in the configuration layout.

Permissions and user/group ownership are no longer defined in separate files -- instead they are specified within the rules file itself. Look at /etc/udev/rules.d/udev.rules for examples.

This means that any custom permissions need to be moved into a rules file like /etc/udev/rules.d/udev.rules or /etc/udev/rules.d/00-my.rules.

See the udev(8) manpage for more information on writing rules.
