 Posted: Mon Oct 20, 2008 5:17 pm Post subject: Four questions about the gentoo ndivia guide |
 |
|
http://www.gentoo.org/doc/en/nvidia-guide.xml
1. Why does the guide suggest I comment out DRI?
| Code: | Section "Module"
(...)
# Load "dri"
Load "glx"
(...)
EndSection |
2. What are the repercussions of not commenting out "Load dri"?
3, What are the repurcussions of not typing
| Code: | | eselect opengl set nvidia |
4. How can I tell whether or not someone has typed "eselect opengl set nvidia"?
Thank you,
Chris
EDIT: Answer to 4 is:
| Code: | | eselect opengl show |

I think it has to do with how nvidia does dri... I have it commented out, and I have dri anyway (glxinfo will show you this) | Quote: |

try it out... probably just give you warnings in xorg.log | Quote: |
3, What are the repurcussions of not typing

VERY slow 3d acceleration. Unusable for games. | Quote: |

Hi folks,
To question 3:
Nvidia opengl unusable for 3D games? - Not with my nvidia card!
I always use Secondlife with pretty fast 3D accelleration with all grafic's options in SL turned on.
Also with 4 x Antialiasing!
My nvidia opengl driver always seemed to be much faster than the one provided with xorg.
But there's a simple test I always do to ensure that opengl works fine:
First switch to xorg's opengl by...
# eselect opengl set xorg-x11
...and now run...
# glxgears
...from a console which will show you the fpts that could be reached
Afterwards, switch to nvidia by...
# eselect opengl set nvidia
...and then perform the same glxgears test and ou will see which one is better.
glxgears is in the package x11-apps/mesa-progs
Good luck,
yours Henri |

AFAIK, nvidia will always be better for nvidia cards... by quite a lot.
sorry if my wording was ambiguous.
