Title: How do I disable auto sleep?
Post by: Karthanis on June 17, 2011, 09:58:34 PM: I'm using an Atom based machine to monitor 12 webcams at a hotel.

I use a html files that is the home page for Firefox and have setup TinyCore so the dock just has icons for Firefox and Shutdown.

The machine isn't ever touched once it is running, but the screen keeps going to sleep....

How do I stop this from happening? I choose TinyCore over Ubuntu so I didn't need to strip everything out of it, but keeping the screen on so the staff can see the cameras is EXTREMELY important. I'll have to reload if TC can't handle it...

Please help? Thanks!

Try xset s off and see if that does it.

Post by: Karthanis on June 17, 2011, 10:32:15 PM: I am testing that out now. Thank you for the very quick (17 minutes?!?!?!?) reply!

Question I have though, if this works, will it be persistant? Do I need to put a file into .X.d to call it all the time?

You can add the command to /opt/bootlocal.sh.

xset s off

to ~/.xsession

Post by: thealy on September 29, 2011, 03:58:49 AM: I have just started to use TinyCore and I have a similar problem with auto sleep coming on when not required, I need the monitor on all the time for the application that I am using (displaying an Openscenegraph model).

I have entered in : xset s off at the command prompt, however the auto sleep remains on and the system goes to sleep after a period (wakes up on a keyboard press). I have also added xset s off to /opt/bootlocal.sh and ~/.xsession and restarted (with a backup), but again the system goes to sleep after a period. The /opt/bootlocal.sh file still contains xset s off however the ~/.xsession file does not (both were edited using sudo).

I am using TinyCore V4.0 and I have also installed the ati-fglrx and ati-catalst packages for the graphics card I am using (which all work okay).

Any further help will be useful, thanks.

Terry

I put the xset command in ~/.X.d/xset and that cured the problem

Post by: thealy on September 29, 2011, 05:13:44 AM: HI Juanito thanks for the quick reply. Have just tried this and restarted system (xset s off is still in ~/.X.d/xset at reboot), but system is still going to sleep on me (for info : other OS on the same system don't do this so I'm sure it's a TinyCore setting that I'm not getting right). Any other ideas ? Thanks again. Terry

Post by: thealy on September 29, 2011, 10:27:44 AM: adding :-

xset s off
xset s noblank
xset -dpms

to the ~/.X.d/xset file has worked for me.

Thanks.

Add a section to /etc/X11/xorg.conf
---
Section "ServerFlags"
Option "blank time" "0"
Option "standby time" "0"
Option "suspend time" "0"
Option "off time" "0"
End Section
