direct rendering on i810

luminiscence · 09-10-2005, 10:49 AM

Hi all,
I had Suse installed on my comp earlier, and direct rendering worked in it. I have just installed gentoo, and I don't know what to do to make direct rendering work. Movies and stuff are working perfectly, but when I do
glxinfo | grep rendering
Then it returns "direct renderng:no". Similarly glxgears gives a fps of 100.

I have Intel 845 motherboard (I guess the graphics driver is i810). I am pasting my xorg.conf below:

Code:

Can anyone help me to start direct rendering? Any help/pointers would be helpful.

Thanks

you have DRI enabled in ur Xorg

"Direct Rendering Open Source Project. The Direct Rendering Infrastructure, also known as the DRI"

You have "dri" enabled in your config, so the first step is correct.
If i remember correctly, the i810 driver supports dri only on some depths.

Code:

from the i810(4) manpage
The driver supports hardware accelerated 3D via the Direct Rendering Infrastructure (DRI), but only in depth 16 for the i810/i815 and depths 16 and 24 for the 830M and later.

Since you have 845 chipset, dri should work with 24 bit depth also.
Check /var/log/Xorg.0.log to see the error.
For example in my i810 it used to have "24 bit depth, disabling dri" error (not exact message but something like that)
Maybe there is something that disables dri
