vga switcheroo not working on amilo Xi 3650
Eric Valette
As I saw some changes in the .35, I tried again on amilo xi 3650. As you
will see its a Intel/Nvidia hybrid graphic laptop.
When I use the delayed switch option, and restart X via the kdm restart
X server option, I see the message of the switch and then it hangs rock
solid. I'm forced to push on the power button for 5 s.
vga_switcheroo: client 0 refused switch <== exiting the kdm session
vga_switcheroo: setting delayed switch to client 1
vga_switcheroo: processing delayed switch to 1 <== restarting X server
If I use the bios, to force the cards, both settings works correctly,
hybrid mode also works correctly as long as I use the Intel card but I
cannot activate dynamically the nvidia one via vga switcheroo.
Problem is that to have the hdmi output on this laptop I'm forced to use
the nvidia driver and my kid like to see their film on TV...
uname -a
Linux pink-floyd2 2.6.35-rc4-git5 #142 SMP PREEMPT Mon Jul 12 22:54:13
CEST 2010 x86_64 GNU/Linux
lscpi and dmesg attached. Is there anything I can try to make it work or
debug? Actually the drivers are in kernel.

[drm:i915_init] *ERROR* drm/i915 can't work without intel_agp module!
doesn't look good,
though I still haven't had a successful intel/nvidia switch as I lack
the hardware, and nobody has worked out exactly which ACPI method is
used to switch the MUX.
if you can get a dmesg with i915 and nouveau loaded then open a bug on
bugs.kernel.org I can try and work with you to figure that out,
Dave.

Yup please do, attach those two files.
We might have to play guess the switch method.

Also if you could try disabling the nvidia, with echoing OFF then ON
and post that dmesg as well.

Done. Attached in the bug report.
