Hi to all, I've been using Raspberry Zero W until some days ago, obviously using embedded wireless module.
Now I can't see wlan0 in ifconfig command.
Where can I start debugging?
Thanks.
Posting the output of 'sudo journalctl' in code tags may help.

Re: Run Chromium as Pi User in rc.local

Matchbox is not functionally equivalent to LightDM (which is a display manager, not a window manager). The terms are a bit confusing, but a desktop manager handles starting xsessions, among other things.

Google can't find it for me.
The source is a forum post where a person claims to have caught a glimpse of some photo in an unspecified pdf over the shoulder of an unspecified person.

I'd love for the pi to be some part of that hardware, but there's really no evidence of that being the case.

Re: Run Chromium as Pi User in rc.local

You can do stuff like su pi -c "foo", but why not do it properly and configure lightdm to do what you want instead?

Re: /etc/inittab no longer present in Raspbian Jessie?

Use raspi-config to disable serial shell instead of the way they say in the tutorial. You want to keep the hardware enabled, but disable the shell (it should ask you two questions).

chromium-browser, not omxplayer. I was thinking there might be a difference in how it's launched or perhaps a warning in the output.

Re: How does Raspbian handle Scratch 2.0?

Scratch 2 is based on Flash and can run in a browser. Adobe AIR is a way to turn Flash into something that resembles a real desktop application. Another way of doing that is 'Electron', which is stripped down chromium and what we use. I'll avoid going on a rant about Electron.

Regarding chromium, the version in the Raspbian image is done by Raspberry Pi Trading, not Raspbian. Yes, that's built manually and infrequently.

Re: Raspbian repo lack of updates

You're making a few too many assumptions. Raspbian tracks Debian, which isn't a rolling release distro. Once a release (in this case 'stretch') is ready, packages only get updated when they have to be (mostly just security fixes). New packages are built and added all the time, but not in the stable ...

Re: No Wifi connection to Pi Zero W after Raspbian update

If I could reproduce the issue, I would start by installing updates one by one and see what breaks it.

Edit: Also, did restarting dhcpcd after booting kick it into life?

Re: GStreamer and omx encoding from live source.. a naive problem

Sure, that makes sense then. Debian errs on the side of caution when it comes to /etc and preserves the changes that the user makes. By removing the file, you've told dpkg that you don't want it there. Then when the postinst script tries to make that the default gst conf, it rightfully complains. ht...
