I have a Lenovo N200 with a GM965 chipset (X3100 graphics). I tried lots of different settings combinations in xorg.conf. When Direct rendering is enabled both glxinfo and glxgears give this error: "Failed to initialize TTM buffer manager. Falling back to classic." glxgears looks weird, is really slow (60 fps) and messes up everythin on the same "height" (screenshot attached). The affected windows/parts-of-desktop are redrawn after moving something on top of them etc. I'll attach a screenshot. Games tend to crash the system - besides the fact that I can't see much. The system is unresponsive then but sometimes shuts down cleanly after I press the power button. (I'm not sure if it's critical but it does crash and hang...) Reproducible: Always Steps to Reproduce: 1. startx 2. run glxgears or some other accelerated app Actual Results: It looks as on the screenshot. Affects other apps. Uses very little cpu (2%). Expected Results: Should look normal and run faster.

Created attachment 164923 [details] output of glxinfo The "Failed to initialize TTM buffer manager. Falling back to classic." line is from the stderr and not stdout (ok I don't if it's written in C but I guess you get what I mean). So when I did 'glxinfo >> glxinfo-output' it was on the console and not in the file.

I can confirm this bug, on my system it occured after an emerge --deep --update --newuse world, which gave me xorg-server-1.5.0 and xf86-video-i810-2.4.2-r1 . No program using GL works, most just show a black screen and lead to an unresponsive system (with MagicSysRq working). Others (like glxgears) just display ""Failed to initialize TTM buffer manager. Falling back to classic." and die after a few seconds with a SIGSEV. glxinfo completely messes up the screen, leaving only a strip of about 20 pixels on the top of the screen intact, the rest is covered with a noisy white (don't know how to describe it better). The system is totally unresponsive in such a situation. Worse that that, even after downgrading to xorg-server-1.4.2 and xf86-video-i810-2.4.0 the problem stays the same. I attached the output of emerge --info, lspci -v, my xorg.conf and my Xorg.0.log.
Created attachment 164933 [details] my lspci -v output I guess I should submit that as well :)
Good news, I have a workaround for this problem. It seems it is not related to the version of xf86-video-i810. After I downgraded libdrm from libdrm-2.3.1 to libdrm-2.3.0 and mesa from mesa-7.1 to mesa-7.0.3, at least glxgears works without any problems. I yet have to check whether this is libdrm or mesa related and if the problem also occurs with xorg-server-1.5.0. I have not yet checked any other GL-using programs, but I will do so after submitting this comment.
(In reply to comment #11) But with xorg-server-1.5.0 I can't downgrade mesa below 7.1 therefore I can't downgrade libdrm below 2.3.1. So unless I want to downgrade also xorg (which I don't) there is no workaround for this (yet).
Could you guys try disabling framebuffer compression? Thanks
(In reply to comment #13) > Could you guys try disabling framebuffer compression? > > Thanks > Didn't change a thing - it still looks ugly/weird and is just as slow. Thanks for interest though :)
Hum, this bug is beyond my knowledge... All I can suggest now is to open a new bug in FreeDesktop's bugzilla : https://bugs.freedesktop.org/ Please read http://intellinuxgraphics.org/how_to_report_bug.html before filing the bug, and please add "remi@gentoo.org" as a CC there. Thanks
Done. It's here: https://bugs.freedesktop.org/show_bug.cgi?id=17491 I changed it to UPSTREAM. If I should not have done so then please change it back or notify me.
Nope, that's fine. A big thank you for taking the time to open the upstream bug. See you in FreeDesktop's bugzilla :)
