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, ~pyther
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. Eg http://www.phoronix.com/scan.php?page=article&item=xorg_kms_2008&num=1 http://www.phoronix.com/scan.php?page=search&q=GEM http://www.phoronix.com/scan.php?page=search&q=TTM
