trouble with /dev/nvidiactl permission

English Applications
#1

hello

from some CAD and FEA sofwares i get the following msg

NVIDIA: could not open the device file /dev/nvidiactl (Permission denied)

and the software as a strange behavior after that, many crashes!
if i do that all works ok

chmod 666 /dev/nvidia* &

this puts the permissions to
nvidia* root.video crw-rw-rw-

however on reboot the permissions are revetred to
nvidia* root.video crw-rw----

how to make this change permanent

thanks

i do know if this best posted in Forum: Applications

Simply add your user to the “video” group.
See: https://www.suse.com/releasenotes/i386/openSUSE/12.3/RELEASE-NOTES.en.html#idm1265054156

But that should already be fixed with the latest systemd update.
What version of systemd do you have installed?

rpm -qi systemd

one of the application, Gmsh, seems to work
another one, Salome, keeps crashing, maybe for another reason!

That’s the older version.
Please bring your system up to date by running YaST->Online Update, Apper or “sudo zypper up”.

#5

i have done and it seems to work ok

i am very reluctant to let the update be done automatically
sometimes libraries get replaced by newer ones and my technical software do not work anymore
and these software are big ones, the largest is 5.5 Gb on disk

and some have very strange requirement, a CAD program requires “libaudio2”??

in a recent past many updates would kill “kfind” for some unknown reasons

#6

That would indicate problems with your repo setup. Libraries don’t get upgraded in the standard repos including the update repo (only security/bug fixes are applied). That should only happen if you install them manually from a different repo since libzypp also doesn’t change the vendor by default.

So check your repo list and remove unwanted/unneeded repos.
And if you run YaST->Online Update or “zypper patch” ONLY updates from the standard update repo are considered, which should be safe in any case.
You can configure the update applet to do this as well, just add the following line to /etc/PackageKit/ZYpp.conf:

HidePackages=true

and some have very strange requirement, a CAD program requires “libaudio2”??

On my system only gstreamer-0_10 (gstreamer-0_10-plugins-bad-orig-addon to be precise) needs libaudio2.
So this could be an indirect dependency. What output do you get when you run:

rpm -e --test libaudio2

If you find the dependency strange, than you should consider reporting a bug to the provider of the package, it might be a packaging error.

in a recent past many updates would kill “kfind” for some unknown reasons

Never had problems with that. And I install many more updates than just the standard ones.

#7

thanks for you very clear explanation about the way updates are done, i will take that into account!

maybe i had some troubles when trying to compile one appli from source and the required libraries

regarding libaudio2 it is mandatory for “dassault-systemes-draftsight” i suppose to be able to play some audio animated tutos
if so i wonder why it is mandatory?

i cannot find out why i had kfind deleted at several instances, but this not important

the more i go the more i try to use software as close as possible to pure X dependancies,
“worker” for example as a file manager pleases me very much

#8

Well, you would have to ask them.
Maybe it’s built in a way that it won’t run without libaudio2 installed…

Btw. libaudio2 is a client library for NAS, the Network Audio System.
I doubt that you use that anyway.:wink:
