Problem with experimental intelhd driver  
I'm not able to get an experimental intelhd driver to work on an Aaeon TF-EMB-QM67-A10.  The experimental intelhd driver
 comes from intelhd-6.5.0-bin-20110908.tar.gz and is 102582 bytes.  The Aaeon TF-EMB-QM67-A10 has an Intel Core i7-
2710QE CPU running at 2.1 GHz and an Intel Core i7/i5 QM67 chipset.  We'd like to have one Photon console displayed via 
the LVDS output and another Photon console displayed via either the DVI or VGA output.

I tested the experimental intelhd driver by replacing /lib/dll/devg-intelhd.so with the experimental version and adding 
an entry for 8086:0116 to /etc/system/enum/devices/graphics.  The system was configured to use the svga driver and the 
VGA output, so I logged in as root and tried to change to the devg-intelhd.so driver.  It displayed the following dialog
:

 In order to obtain correct graphics settings,
 the driver needs to be changed
 immediately.
 Do you want to do it?

When I selected the Yes button, the screen went black and nothing else was ever displayed.
Re: Problem with experimental intelhd driver  
It seems that the 'experimental' driver caused the system to hang-up, or 
caused the default driver (that should have kicked back after ~15 seconds) to not initialized the adapter properly -- 
hence the blank screen.

Can you telnet to the box after this happened?
Re: Problem with experimental intelhd driver  
Yes, I can telnet to the box after switching the graphics driver.
Re: Problem with experimental intelhd driver  
-- sloginfo 
-- see if io-graphics has crashed. if not, do 

 pidin -P io-graphics mem
and
 pidin -P io-display mem

do you see that an appropriate devg-* is loaded in both?
Re: Problem with experimental intelhd driver  
I've attached the output of sloginfo.

devg-intelhd.so is loaded in both io-display and io-graphics.

Re: Problem with experimental intelhd driver  
After acceptance of the driver change you have about 15 seconds to confirm that the new driver is okay. If you see 
nothing on the screen you should not be able to confirm, this should cause io-graphics to revert back to the original 
driver. It looks like io-graphics didn't revert back.

Try your driver by without photon:
--  manually change /etc/system/config/display.conf 
-- starting io-display from a command line
-- run demo-alpha
Re: Problem with experimental intelhd driver  
The screen goes black and the system stops responding to the keyboard once I start demo-alpha.  Here are what appear to 
be the only relevant lines from sloginfo:

 Feb 06 11:19:10    6     8     0 VGA primary : bus 0x0 dev/func 0x10
 Feb 06 11:19:10    6     8     0 Found 1 PCI/AGP display devices
 Feb 06 11:19:10    6     8     0 pci_init: found PCI device 8086:116

If I configure the system to use the svga driver, the demo is displayed and responds to keyboard input.  When it exits, 
the system goes back to text mode.
Re: Problem with experimental intelhd driver  
The driver is the problem. It may not be compatible with your system. 
Contact the developer.
Re: Problem with experimental intelhd driver  
We were sent a new experimental driver, intelhd-6.5.0-bin-20120209.tar.gz.  Using it, we are able to switch to the 
intelhd driver successfully.  Unfortunately, I haven't been able to configure it to use multiple displays.  When I try 
to do so, Photon fails to start.  I've attached one of the display.conf files that I've tried.  Does the intelhd driver 
support multiple displays?  If so, what am I doing wrong?

Re: Problem with experimental intelhd driver  
where might one acquire this experimental driver?
Re: Problem with experimental intelhd driver  
I received it from QNX.  You'll need to contact them if you'd like a copy.
