were you using the mesa tip? we once saw this in the last a couple of days, but was fixed quickly... can you retry the tip?
Comment 6 Max 2008-01-07 02:45:10 UTC
when i downgrade mesa from svn to mesa-7.0.2, xf86-video-i810-9999 to 2.1.1, and xorg-server, warnings and errors disappear.
Comment 7 Michael Fu 2008-01-08 21:02:58 UTC
Have you tried the tip?
Comment 8 Gordon Jin 2008-01-08 22:19:27 UTC
The log shows:
(EE) AIGLX error: dlsym for __driCreateNewScreen_20050727 failed (/usr/lib/dri/i915_dri.so: undefined symbol: __driCreateNewScreen_20050727)

You need use xserver tip together with mesa tip. See

After some dwelling in the bug reports, I guess "tip" means the latest GIT version, and people are confused about "tip" meaning just that, tips to solve problems... I haven't heard of using "tip" for trunk/master/head/latest git/latest cvs, so it might be a wise idea to avoid that word :)

So: using current mesa's GIT/master version requires also the GIT/master of xserver instead of the 1.4-branch. Ie you need git://anongit.freedesktop.org/git/xorg/xserver in addition to the latest mesa/drm and mesa/mesa. Hope this helps.

thanks Timo's explanation.

Max, need your response for comment# 8...
Comment 13 Timo Jyrinki 2008-02-04 03:51:01 UTC
I think the TTM problems can be confirmed regardless of the fact that the original reporter did not use Xserver's latest git version. I and some other(s) are not able to get TTM enabled either even when using latest version of Xserver & drm & libdrm & mesa & intel ddx, see bug #14314.
Comment 14 Timo Jyrinki 2008-02-05 00:33:43 UTC
Actually it turns out that I still had an old libdrm.pc pkgconfig file, which reported older version, which disabled DRI_MM in the intel DDX driver. For newbies it might be useful to note in Xorg.0.log that the driver was compiled without memory manager support.

TTM works now, so this bug can be fixed/closed.

I still see 'Failed to initialize TTM buffer manager.  Falling back to classic.' on Gentoo with the following packages versions:

$ eix -c media-libs/mesa -o x11-base/xorg-server -o x11-drivers/xf86-video-i810
[I] media-libs/mesa (7.2_rc1@16.09.2008): OpenGL-like graphic library for Linux

The same happened with Mesa 7.1

Denis, having this warning is expected with current mesa code, as TTM is disabled by default in 7.1 and 7.2.

If that's the only issue you have, please close this bug.

Mass version move, cvs -> git
