DetailsHi there, my intel X4500 (G43 Chipset) doesnt seem to do proper 3D with Xorg from testing. Apart from glxgears (that runs with about 500 FPS, but i dont know if its hardware 3d or now), everything seems to run with software rendering = ultra-slow ... So far i have tried Tremulous, Tuxracer and some GL Screensavers, and they run fine on another machine with intel X3100 (G31 chipset) but not on this one. Also neither compiz or KWin compositing run, they just give my a white screen. According to this article... http://www.phoronix.com/scan.php?page=article&item=intel_x4500hd ...the X4500 is supported since Xorg 7.4 / Mesa 7.1 / xf86-video-intel-2.4.0 I conclude that here must be a bug somewhere (or i am just too dumb to configure it properly :D) glxinfo tells me that direct rendering is enabled, but there is an error in Xorg.0.log that tells the opposite(?): (EE) AIGLX error: drmMap of framebuffer failed (Invalid argument) (EE) AIGLX: reverting to software rendering (There is a lot of stuff on Google about this error, but i have found no solution yet) So far i have tried it with my xorg.conf and an autogenerated one (X -configure) and also with EXA/XAA and all this stuff... Everything leads to the same problems... It would be nice if someone could tell me whats the cause of this. I am happy to provide more info if you need it. Greetings Jan

This task depends upon
(II) intel(0): direct rendering: Failed
http://bugs.freedesktop.org/show_bug.cgi?id=5901
http://bugzilla.kernel.org/show_bug.cgi?id=7767
So far no solution in sight... I have also opened a bug at the freedesktop bugtracker:
https://bugs.freedesktop.org/show_bug.cgi?id=17690
Thanks
I have 2 entries in my bios for the graphics card memory:
1. Shared Memory
2. DVMT/Fixed Memory
As these are not really documented in the handbook i just set both to 256MB because i have plenty of RAM,
but it seems that "share memory" allocates memory for 2D only and "DVMT/Fixed" Memory is the entire
graphics memory that can be used for 2D and 3D together... The result when setting both to 256mb is that
256mb will be allocated for 2D and nothing is left for 3D, which leads to the Xorg error. Now i have set
"share memory" to 32mb and everything is working properly and damn fast for Intel graphics :)
Just check the freedesktop bug for some more details and stuff.
Greetings
Jan
