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.
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?
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 Paul
Try: setterm -powersave off -blank 0 Or: xset s off Here are some good explainations: http://www.cyberciti.biz/tips/linux-disable-screen-blanking-screen-going...
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
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
add this to your bootargs variable consoleblank=0 i share mine in the old discussion, hope it worked on yours.
