Re: changing DNS-servers

This page might help you find your setting. https://wiki.debian.org/NetworkConfiguration#Defining_the_.28DNS.29_Nameservers Network Manager wasn't the cause either, already checked the other files mentioned. Thanks for the reading material though ;) (That new bookmark will probably come in handy fr...

changing DNS-servers

Somewhere in the past, I configured Raspbian to use Google's DNS servers. Since those are quite slow when it comes to picking up DNS updates, I want to switch DNS servers. The problem is, I can't remember where I set it to use Google's DNS servers. The only file I found with Googles DNS servers in i...

Re: Pi won't boot, ACT light is solid green

So you are using this PI "headless", that is without it having a monitor of its own.... correct?! And you connect your TV receiver to the PI over USB to stream TV programs to Ethernet. correct? Correct, times two You are NOT in any way using the TV receiver as a means to connect a PI's HDMI (or com...

Re: Pi won't boot, ACT light is solid green

I don't understand this: But still, it couldn't have leaked through hdmi since the hdmi-connector isn't being used, my tv doesn't even have hdmi (too old). The died Pi used a DVB-C receiver with coax connector and it's connected to the Pi by USB, its not connected to a tv (or pc monitor) at all. So...

Re: Pi won't boot, ACT light is solid green

Let me say first, that if you believe your PI to be defective, then please return it to the reseller under the guarantee that you should have. Tried that, unlike most products sold in this country, RPi's only have a 1 (instead of 2) year guarantee. I've had it a little under 2, so the store's no he...

Re: Pi won't boot, ACT light is solid green

Thats the normal state when not booting, or just in rest, at least for all recent PI's, except the Zero (w). So it basically means it hasn't started trying to boot form the microSD card? Since the network interface isn't even being enabled, it's not getting very far, if it actually tries to start t...

Re: Pi won't boot, ACT light is solid green

I seem to have the same problem with my Pi2. Was working fine 2 days ago, shut it down, turned it on today: Red+green LED light up continuously and at the same brightness. Just like some others a few posts above, I did something with an USB device before the last shutdown. I disconnected a smartcard...

Run code for a Teensy on a Pi

Not too long ago I got my hands on a cheap oled-display and the only documentation I found (besides a 2 page datasheet ) was https://github.com/sumotoy/OLED_pictivaWide , with example sketches written for a Teensy. I'd like to hook it up to a Pi Zero W and I think that could work, if I can write a p...

I just wanted to try that, only to find out I can already suddenly change the volume using alsamixer and I have no idea how that happened :? Maybe some changes require multiple reboots to work?

Tl;dr: See title, that pretty much sums it up. To get a bit more detailed: I have an Adafruit speaker bonnet (I2S DAC) on a RPi Zero W running Raspbian Jessie Lite.

Got it, thanks :)

Turns out "write_enable=YES" got commented during the upgrade, causing 550 permission errors when I tried to do anything (rm/create/mv/cp).
