Title: A13 with 4.3LCD Problem
Post by: wolo2663 on February 08, 2014, 04:58:23 PM
Hi all,
I recently received my A13 with 4.3" Touchscreen. I managed to get it all working, except that the LCD turns off after about 5 minutes of running. Before turning off, it works as expected. If I leave it running, it sometimes turns itself back on (after maybe 30 minutes). Does anyone know what might cause this? Does it sound like a hardware or software problem.

System details:
Latest official Olimex Debian image
12 V, 1A power supply
Only keyboard and mouse connected to USB ports

Thanks.

UPDATE:
Looks like it isn't a problem with the LCD. The VGA output also produces similar behavior.

Sounds like screen/power saver.

If you don't want them, turn them off!

Thanks John,

Checked the screen saver, not enabled in gui
Also power settings are not enabled.
Could you point out which file to check via a terminal.

It is for sure some standby issue, since if I keep working on the scrren this issue does not arise..

Try putting this somewhere in /etc/rc.local:


setterm -blank 0


(there are more posible options, but this will be probably enought).

And if you use XWindows, put this in /etc/X11/xorg.conf (you will probably need to create the file):


Section "ServerFlags"
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
EndSection
