Comment 98 for bug 245888

I am afraid the fix does not work for all the machines. Before writing this, I posted a question, and MarcoBra eventually advised me to fill a new bug report or to post here -- I think a new bug report would not be appropriate.

Problem: on several occasions (e.g. if I type "glxinfo | grep direct"), I get the error message (or warning):
"Failed to initialize TTM buffer manager. Falling back to classic."
I never got it under Hardy. "Compiz.real" outputs several error messages and leaves the screen "stuck" -- I mean, the windows become unresponsive, and I get back only by choosing an option from System/Preferences/Appearance/Visual effects. Btw, no radio button is selected by default in that menu.
I have Intrepid alpha5, updated, upgraded and distro-upgraded on Sat Sep 13.
Details from lshw -C display, lspci and xconf.org are attached to question #45103.
Briefly, my gr. card is Intel 943GML.
The interesting thing is that I installed Fedora 9. As soon as the install was done, I type "glxinfo" in a Terminal and got the error "Failed to initialize TTM buffer manager. Falling back to classic." But I did a complete update and upgrade (which took several hours): after that, the error message _disappeared_.
[Fedora 9] uname -r
2.6.25.14-108.fc9.i686.
Therefore, I guess there is a real issue that has still to be solved in Intrepid.
One more detail that might be of some help for a (possible) debug. My display card is marked as "unclaimed". If I try to install a driver (via gksu displayconfig etc.) the only available driver is the i810 (which gives a lot of trouble: I ended by resetting the xorg.conf and keeping the unclaimed display). Fedora suggests another driver by default: that is, an "experimental driver for Intel integrated chipsets", which is explicitly tailored for the 943GML (as well as for other Intel integrated cards). My guess is that this driver, or a similar one, would improve the hardware compatibility between Intrepid and machines mounting the 943GML.
This might be a nice case of cooperation between distros :-)
