Screen goes blank

Paul
Hi guys,
I know that this has been discussed before but nobody is giving me a good
answer.

How do I stop the mini2440 screen from going into power saving mode?

The screen can be switched back on by plugging in a usb keyboard and
pressing a key but this doesn't do it for me.

I'm using friendlyarm's latest kernel + OE filesystem.
Thanks a mil
Paul

I already have given an answer in another thread before. You need to switch
from "backlight" to "default-on" trigger in
/sys/class/leds/backlight/trigger.

Paul
Hi Jay,
I don't have such a class, I have 
/sys/class/misc/leds/ which leads to /sys/devices/virtual/misc/leds

and

/sys/class/misc/backlight/ which leads to
/sys/devices/virtual/misc/backlight

no trigger in either one...
Any ideas?
Thanks
Paul

Which kernel version are you using? If you use an older one, there isn't
such property. Maybe you should use an actual 2.6.32 or my 2.6.33 one.

I have installed debian and the x11 server...
almost fine and the touch is also working with one exception
i cannot click anyting with it i can only move the crusor.

On a standard X server, xset is the utility to control the screen blanking
interval.  'xset s 0 0' should disable it, possibly combined with 'xset
dmps 0 0' if blanking is done through DPMS.

Andreas: Can you explain how you have configured your X11 server? Could you
post your x11/xorg configuration file so that I also could try, I can then
report how it works on the kernel I'm using. Are you using icewm, jwm or
what windowmanager?

Paul
Andreas, if the post isn't relevant please post it as a new topic.

Jay, I'm using FriendlyArm's 2.6.32.2 with only a few changes.

Thanks a mil

Try: setterm -powersave off -blank 0
Or: xset s off

Here are some good explainations:

Thanks Jay,
I don't have setterm in my busybox but will try to cross compile it and
move it across in a while.
In the meantime, I may have found an answer:

echo -e '\33[9;0]\33[14;0]' > /dev/console

My terminal is still on and its been a few minutes, so I'm keeping my
fingers crossed :)
Talk soon
Paul

Paul
Doh, doesn't work...
I've cross compiled setterm and when I run it I get 

no option -powersave 

... ok no problem there, but when I run 

setterm -blank 0

I get

setterm: 0 must be between 1 and 60... wtf?
can my terminal not be configured to always stay on?

Thanks for the help Jay, I ve got everything working but the bloody screen
turns off on me :P
Cheers
Paul
