<DIV>After I use 3.4 rc6 kernel which contains IVB_GT2_IG, intel agp and
VGA are recognized now.</DIV>
<DIV>The "lspci" command now shows that PCI 00:00.0 uses Kernel driver
agpgart-intel and PCI 00:02.0 uses i915 now.</DIV>
<DIV>before I use the 3.4 kernel, there was nothing about the driver info.</DIV>
<DIV> </DIV>
<DIV>The <SPAN style="FONT-STYLE: italic">/dev/dri</SPAN> folder is created now,
containing <SPAN style="FONT-STYLE: italic">card0</SPAN> and <SPAN
style="FONT-STYLE: italic">controlD64</SPAN>.</DIV>
<DIV>But the <SPAN style="FONT-STYLE: italic">/var/log/Xorg.0.log</SPAN> still
complains about "No devices detected", after loading </DIV>
<DIV style="TEXT-INDENT: 2em"><SPAN
style="FONT-STYLE: italic">/usr/lib/xorg/modules/drivers/intel_drv.so
</SPAN>.</DIV>
<DIV> </DIV>
<DIV>And there is also an error in the "dmesg" output:</DIV>
<DIV> [drm:intel_dsm_platform_mux_info] *ERROR* MUX INFO call
failed</DIV>
<DIV>I don't know whether it has anything to do with the Xorg error.</DIV>
<DIV>Thanks</DIV>

<DIV>It is in included in intel_agp.c.</DIV>
<DIV><BR></DIV>
<DIV>But I suspect that the problem is that you are missing the IVB GT2 Server
variant support, which we added this April.</DIV>

<DIV>Could you post your "lspci -n | grep 00:02" output please?</DIV>
