Hello.
I have updated to Xorg-server 1.5 from testing. However I get extremely low
fps (60fps) when running glx-gears. The error I get in the terminal is
"Failed to initialize TTM buffer manager. Falling back to classic."
After googling I came across this bug report on gentoo tracker:
http://bugs.gentoo.org/show_bug.cgi?id=237468
>From my research it appears that many people who have Intel cards have this
issue. I have the Intel 82945G/GZ using the xf86-video-intel driver. From
the bug report it seems as if no work is going into supporting TTM, instead
all the work with the driver is going into GEM support. I am not sure what
TTM and GEM are, which makes my understand weak with the issue at hand.
>From what I do understand it has something to do with dri (a backend?)
I have updated libdrm to 2.4.1 and xf86-video-intel to 2.5.1 and continue
to receive the error as many others do. I am currently in the process of
compiling a new kernel that has GEM support. Following the directions from
comment 41 of the bug report.
>From reading though the bug report is seems as if this GEM technology is
unstable and not ready for any type of release.
If xorg-server 1.5 is moved from testing to extra, can we have an archive
of xorg-server 1.4 and all related packages? This migration is going to
affect a lot of archers with Intel cards. Many archers require much higher
frames per second. By providing an archive of these packages it will allow
new installations and people who upgrade a chance to downgrade to regain
performance.
Hopefully I was clear in my explanation if not feel free to ask me any
questions. Thank you for taking the time to read this.
Thank you,

I don't remeber what GEM and TTM are either, but I've read about it on
phoronix.com. That site has lots of articles related to graphic
drivers, xorg etc.
