Hey all,
This is a problem I had a while back but am having again on a 10.2
install I am trying to get setup.
The nvidia driver setup from their site runs fine and installs.
Running openGL apps I get
NVIDIA: could not open the device file /dev/nvidiactl (Permission
denied)
Which makes sense because my LDAP user is not part of the video group
and the perms on nvidiactl look like
crw-rw---- root video
Changing these permission via root and restarting the application as
the user makes things peachy .. until they reboot and the perms are
reset to these defaults.
Now it is my understanding that udev creates the device nodes on
startup according to the rules set forth by the various files in /etc/
udev/rules.d
In /etc/udev/rules.d/50-udev-default.rules, there is a line that
looks like:
KERNEL=="nvidia*|nvidiactl*, GROUP="video"
Reading through the man for udev rules tells me that I *should* be
able to add a line like this:
KERNEL=="nvidia*|nvidiactl*, GROUP="video",
MODE="0666"
To give me the permissions I would like these device nodes created
with upon bootup (again this is all under the assumption that udev is
doing something). Furthermore I've gone ahead and turned on the
debug mode for udev. After a reboot searching through /var/log/
messages brings up nothing regarding /dev/nvidia* and the permissions
still remain 0660 instead of 0666.
The only difference I can think of is that 10.2 installs with
Novell's Apparmor by default. Whether that would interact at this
level I am unsure because I haven't done a lot of reading in that
direction. However I am now going to attempt a fresh install without
any extraneous apps. Any help on this topic would be greatly
appreciated.
Cheers
