Enable Direct Rendering
 
Hi, I am running Mandrake 10.1 and just installed UT2004 and noticed a problem with my FPS. I have a 3GHz P4 with GForce 6800 GT OC 256MB graphics and 1GB ram.

I have done a bit of digging and think that this may be the problem tho I dont know how to fix it.

# glxinfo | grep direct
direct rendering: No

I installed the nvidia driver from their site yesterday and I get the nvidia splash screen when entering X so the driver works. Ill also note that I just installed mdk10.1 a couple days ago and haven't loaded much other then sources for the kernel, kde, Qt, Xorg and a few multimedia apps like xmms xine and so forth.

here is some of my xorg.conf

let me know if you need anything else.

Thanks

sharkee 03-15-2005 02:36 AM
Uncomment the load dri line in your xorg.conf.

#Load "dri"
Load "dri"

Regards
Sharkee

rca36 03-15-2005 10:42 AM
thanks for the reply. Unfortunately, I already tried this, and when i grep the glxinfo it still says direct rendering is disabled. Im at work atm so I cant re-verify but I did have it like this last night.

I will un-comment it again when I get home from work this evening just to make sure.

If you or anyone else can think of any other reason why it would still be disabled let me know.

Thanks

Edit: Do I need both of these in my xorg.conf?

Load "glx" # 3D layer
Load "/usr/X11R6/lib/modules/extensions/libglx.a"

..or should one be removed?

dubya 03-15-2005 03:46 PM
Check the permissions on the nvidia devices in the /dev directory uses this command:
Code:
ll /dev | grep -i nvidia
I am running FC3 and for some reason, whenever I boot, permissions will be set on some of these devices so that only the root may access them. If this is your problem, you will need to modify these permissions so that all users may access them.

Hope this helps. If you don't know what I'm talking about, just post the output of that command I mentioned.

rca36 03-15-2005 06:45 PM
Sharkee-
I uncommented the Load "dri" and rebooted... direct rendering still disabled

dubya-

I ran that command and here is the output:
crw-rw---- 1 rca36 video 195, 0 Mar 15 18:40 nvidia0
crw-rw---- 1 rca36 video 195, 255 Mar 15 18:40 nvidiactl

please advise.

dubya 03-15-2005 07:47 PM
Try running this command as root:
Code:
chmod 666 /dev/nvidia*
This changes the permissions of the devices. Then try:
Code:
glxinfo | grep direct
You should get a positive result if you run that command as root before you change the permissions. After, it should give you a positive result no matter what type of user you are.

However, I have to do this everytime I want to enable direct rendering support. Whenever I reboot, the permissions get reset. So be warned that you may have to do this everytime you need it.

Hope this helps.

rca36 03-15-2005 07:58 PM
dubys-

ok i did that and it sill says direct rendering is off :(

dubya 03-15-2005 08:30 PM
Is the Load dri line still commented out?

Please post the output of
Code:
ll /dev | grep nvidia
Other than that, I'm not too sure...sorry!

rca36 03-15-2005 08:33 PM
dubys-

Load "dri" is not commented out anymore and I tried chmod 666 and it didnt work so I did 777 and it didnt work... here is output:

crwxrwxrwx 1 rca36 video 195, 0 Mar 15 19:53 nvidia0
crwxrwxrwx 1 rca36 video 195, 255 Mar 15 19:53 nvidiactl

dubya 03-15-2005 09:59 PM
Load dri should be commented out, or simply deleted.

I'm not sure how else to help you though. Sorry! Good luck.

rca36 03-15-2005 10:02 PM
Problem Solved!

I was cruising the net looking at various things when i came across a link about a new Nvidia driver so I DLd and installed it. Im not sure it was really the driver tho is prolly didnt hurt, but rather I noticed a blip of text just as i did a startx. So I exited and noticed it was complaining about libglx.a link. I then went and looked at the samble XF86 conf file supplied with the newest nvidia and noticed they have the following:

Section "Module"

# PoLoadr sectio"dbe"

# Load the glx module.
Load "glx"

Load "extmod"

Load "type1"
Load "freetype"
EndSection

so i modeled mine after this and YAY Direct Rendering:yes

thanks again for the help getting me here :)

dubya 03-16-2005 11:18 AM
Congratulations!

MegaByll 03-29-2005 01:15 PM
Finally, someone who has had the exact same problem as I, and actually has the solution. Unforunately I am not at the computer with the linux install, so I cannot try it out yet, but I will be doing so the second I get back. I hope this works for me too.
