Hi Charles,
 
If you can log into the device using the console port, try issuing the following command when the screen shuts off:
 
echo 0 > /sys/class/graphics/fb0/blank
 
That should "unblank" the screen.  If that works, then it is the kernel that is disabling the display.  An ugly way to
prevent this would be to regularly issue the above command.  I think there is a way to tell the kernel not to
blank the screen, but I can't remember how to do that.

Subject: [Gumstix-users] Panel Suspend

 Hi Guys,

I'm using an Overo Fire with a Palo35 expansion board and the LG LB035Q02 display that comes with it.  The problem that I'm having is that the panel shuts off every 9 and a half minutes or so and there's no way to get it back on.  My theory is that this happens when the system goes to sleep, but since it shuts off the panel, and that is my only human interface device, there is no way to get it to wake up again without hitting the "reset" button.  Whenever it happens, it executes a function called "panel_suspend()" which is part of the panel driver.  Does anyone have any ideas about how to solve this issue?

Thanks for any help,

Charles McPherson
