how to enable Direct Rendering

[adrian_mx]

How can I enable direct rendering in a i915 chipset, when using the glxinfo I have the message that direct rendering is off and by reconfiguring xorg and selecting the i810 driver, I still get the same message, I tried installing the drivers from dri.freedesktop.org, and installed them, but still I get no direct rendering, so how can I enable it?
In Ubuntu I did it by upgrading my kernel from 386 to 686, including the kernel headers, and the restricted modules, rebooting into my new kernel, and installing the drivers from DRI, and worked great; but in Debian, that doesn't work, and I cant find the kernel restricted modules, so how can I enable direct rendering in Debian in a i915?

I had the exact same problem on my Inspiron 6000. I tried for ages to get DRI enabled, and the thing that worked for me was to upgrade Xorg to the most recent available (6.8.99.9 - I think it may be 6.9.0 RC3 or something) and test it again. My old Xorg version just wouldn't let the i810 driver (dri snapshot or xorg) access the hardware directly. I think I didn't even have to install the DRI snapshot. However, I've heard reports from both camps that say you definately should / shouldn't install the DRI snapshot.

Most of my info and help came from these sites:

Here's the relevant portion of my /etc/X11/xorg.conf:

Code: Select all

Section "Device"
        Identifier      "i915 CRT-enabled"
        Driver          "i810"
        VideoRam        65536
        Option          "BusType" "PCI"
        Option          "DRI" "true"
        Option          "NoAccel" "false"
        Option          "MonitorLayout" "CRT,LFP"
        Option          "Clone" "On"
        Option          "CloneRefresh" "60"
EndSection

I read that you have to force the BusType to PCI to stop agpgart stubbornly refusing to allow any more than the usual 8 meg "stolen memory". I haven't actually tested my setup without this option - I'll try and post back.

Hope you get it working!
