Re: RasPi Timed Remote Control

Does your TV use IR or bluetooth for remote control? Try searching for "raspberry pi IR remote" or "raspberry pi BT remote" and you will see lots of hits. I'd start there and find one that looks suitable to you. If you get stuck on something, ask! You can schedule a program to execute at your desire...

Re: autologin enabled by update?

Thanks, looks like I'm late to the party suggesting it not be done that way. It looks like it was already changed. Nevertheless I think I'll remove the pi-greeter just to be certain.

Re: SD Cards

Always fun to benchmark cards to see what comes out best. It's not always obvious from the specifications. The problem we have is that some (all?) of the fastest cards are optimized for a continuous sequential data stream as produced by a HD or 4K video camera. That may not translate into similar pe...

Re: autologin enabled by update?

This is a GUI install. I haven't noticed this on any non-GUI installs (e.g. Stretch Lite) but I usually run those headless and might not even notice. Edit: This was on an installation that hadn't been updated in several months. A test case might be to install one of the older versions, disable autol...

autologin enabled by update?

I've updated a couple Pis lately and found that autologin to the user pi is enabled afterwards. I think this is a Really Bad idea from a security standpoint. First of all, I don't typically use the user 'pi.' I use the same user name I've been using for decades on Unix, AIX, Solaris and more recentl...

Re: Raspbian Stretch Headless Setup Procedure

That's kind of a tough situation. If it connects at all, it seems that you have the configuration correct. It may be harder to figure out the delay and that comes down to basic troubleshooting. Do you have a console (monitor & keyboard) available? If so, look at the results of the command 'iwlist sc...

Re: I2C enable doesn't survive reboot.

Smashed it! It turns out that it was not related to the 'pi' user (or lack thereof.) I had been running this Pi (Model 3B) from a USB flash drive and booting from an SD card. W/out realizing the need to mount /boot from the SD card I had it mounted on the USB drive. My recollection is that I had tri...

Re: I2C enable doesn't survive reboot.

I recreated the 'pi' user (but with UID/GID 1001) and reran 'raspi-config'. It no longer reports the "No passwd entry for user 'pi'" error but unfortunately the I2C enable is still not surviving a reboot. :(

If this is not the correct forum to ask this question, where should I ask?

thanks,
