Description Aniruddha Shankar 2002-12-11 00:45:14 UTC
As referenced in bug 7712, the Intel DRM module did not compile. This was fixed on 12/09/02 and I can now compile the DRM module without problems. dmesg shows that the DRM kernel component is loaded :

[drm] AGP 0.99 on Intel i810 @ 0xd0000000 64MB
[drm] Initialized i810 1.1.0 20010616 on minor 0

however, the X log file shows that DRI is disabled :
(II) I810(0): [drm] created "i810" driver at busid "PCI:0:1:0"
(II) I810(0): [drm] added 8192 byte SAREA at 0xc88d4000
(II) I810(0): [drm] mapped SAREA 0xc88d4000 to 0x40017000
(II) I810(0): [drm] framebuffer handle = 0xd0000000
(II) I810(0): [drm] added 1 reserved context for kernel
(EE) I810(0): [dri] I810DRIScreenInit failed because of a version mismatch.
[dri] i810.o kernel module version is 1.1.0 but version 1.2.0 or greater is needed.
[dri] Disabling DRI.

did you select the DRM-4.0 compatibility mode thingus in the kernel 
configuration? (I know nothing about this module really)
Comment 2 Aniruddha Shankar 2002-12-13 18:00:29 UTC
Just tried with DRM 4.0 compatibility mode ... same result, DRI disbled. 

Did some googling around, these links seem promising. They're about this problem and a possible solution seems to be recompiling the DRM modules with Alan Hourihane's patches available here :
http://www.xfree86.org/~alanh/
Unfortunately, I'm out of my depth here. 

These links seem helpful :

http://archive.linuxfromscratch.org/mail-archives/blfs-support/2002/01/1233.html

Please note that with many kernels, including the lolo-sources one, it seems fine. I don't want to use the lolo-sources kernel because I'm having some intermittent problems with heavy load and lots of hard disk thrashing when it does something other than display *simple* webpages. Bug for that will be filed, am gathering info on it.

I believe this is fixed in lolo-sources-2.4.20.1_rc3 please double check that
and let me know.
