Description Rune Schjellerup 2005-10-20 00:19:05 UTC 
I'm trying to run dosbox with output set to opengl. 
But it fails because /dev/nvidiactl is only accessible to root. 
olberd@ip10 $ ls -l /dev/nvidia* 
crw-------  1 root root 195,   0  1 jan  1970 /dev/nvidia0 
crw-------  1 root root 195, 255  1 jan  1970 /dev/nvidiactl 
 
I have also run into this problem with a game, just can't remember which one. 

Reproducible: Always
Steps to Reproduce:
1. emerge dosbox 
2. run a game using dosbox, with output set to opengl 
3. 
 
Actual Results:  
CONFIG:Loading settings from config file dosbox.conf 
Error: Could not open /dev/nvidiactl because the permissions 
are too resticitive.  Please see the FREQUENTLY ASKED QUESTIONS 
section of /usr/share/doc/NVIDIA_GLX-1.0/README for steps 
to correct. 
Fatal signal: Segmentation Fault (SDL Parachute Deployed) 
 

Expected Results:  
Nice OpenGL graphics

It's up to you to create the appropriate devfsd or udev rules for the user(s)
you want to allow to access the device. It's not bad to be restrictive by default.

> /usr/share/doc/NVIDIA_GLX-1.0/README

Which ebuild version are you using? The documentation should be in
/usr/share/doc/${PF}/...

Maybe the device by default should be accessible to group games or something 
like that. 
 
 
>It's not bad to be restrictive by default. 
 
Changing udev rules just sounds a bit difficult. Isn't games or some other 
group appropriate to give access to, per default?
