raspbian - How do I Disable Screen blanking on raspberry pi -


i running raspbian , using display device tv in retail centre.

i run chromium on startup line in .profile

xinit /usr/bin/chromium --kiosk --incognito www.mysite.com

however non of solutions disable blanking seem work (although work if in raspbian gui).

it quite important (as can imagine) display screen not go blank......

does have solutions this?

kbd seems causes screen-blanking.
can disable kbd's screen blanking via it's configuration file, /etc/kbd/config.
open text editor such vi, nano, or leafpad.
note requires administrative rights.
change line

blank_time=30

to

blank_time=0

in order these settings take effect, restart/reboot rpi, or restart kbd with:

sudo /etc/init.d/kbd restart

if still getting blanking after that, changing lightdm's config might fix it.
edit lightdm's configuration file (/etc/lightdm/lightdm.conf, requires root), , add following line after line "[seatdefaults]"

xserver-command=x -s 0 dpms

note have tested kbd method!

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
