Re: How to change display timeout

I am running Raspbian on my Raspberry 2B unit. It works perfectly but I want to figure out how I can change the screen timeout time. I want to monitor a screen for long periods of time and I can't stop the screen from timing out and going blank. Where is this timeout period determined and set? You ...

Re: How to change display timeout

Also the default X screensaver can have it's timeout changed by setting a value in seconds with: @xset s 120 (in this example 120s or 2 minutes). In the Raspbian desktop there are 2 screen-blankers running at the same time both with default 10 min. timeout. So you have to either set both to the sam...

Re: How to change display timeout

If you are using the GUI windowed display, open a Terminal screen and type xset s noblank xset s off xset -dpms That will stop it going blank. Unfortunately, if you reboot the Pi the screen will start blanking again. Still using the Terminal, type sudo nano /etc/xdg/lxsession/LXDE/autostart Add the...

Re: How do I install IDLE for Python 3.7.2?

Is there a reason you need 3.7?
idle 3.7 is not in 'Stretch' but will be in 'Buster' when it is released in a few months.
I think it is possible to change repository sources and get it but you risk trashing the whole system if not done correctly.

Re: Why my IR LED transmitter not transmit any signal?

Are you sure you have the polarity of the diodes correct?
I once worked on a project where the IR emitters that were used had opposite polarity when compared to standard LED's. (Long leg vs short leg)
Had to do much rework.....

Until you do find specific instructions for RPi then you are wasting your time.
See related thread: viewtopic.php?f=91&t=235429

You need to contact the maintainer of that software for help.

That doesn't surprise me, because what you want to do is NOT possible with just a cable. You need a complete driver board with a HDMI input, specially compatible with your LCD panel. That's interesting. If i were to get this board would the board have to take hdmi input or could it take some smalle...
