Re: GUIDE: Reliably wait for network when booting Jessie

Are you sure about this? I have read that any diversion from the standard systemd settings should be in /etc/systemd/system/xxx.service NOT in /lib/systemd. /etc/systemd won't be overwritten by the next upgrade and comes after /lib/systemd .. and therefore takes priority . Of course systemctl enable...

Re: Installing MicroPython - How To Guide

My install on a Pi Zero failed at the step cd unix as the subfolder of ~/micropython was not created during the installation as expected and therefore make clean was not possible, even though I created the folder manually. Any tips from anyone? 3) Building MicroPython for the Pi Code: Select all cd ...

Re: WiFi ONLY works if Ethernet is plugged in

I found a simpler solution using systemd In the file where the various interfaces are defined /etc/systemd/network , make sure the wlan0 file has a lower name that the eth0 file, as follows: [email protected]:/etc/systemd/network$ ls 30-static-wireless.network 40-static.network 99-default.link Now I don`t ...

Re: WiFi ONLY works if Ethernet is plugged in

I had the same problem after converting to systemd-networkd
I traced it to a line in /etc/dhcpcd.conf

denyinterfaces wlan0

I changed it to #denyinterfaces wlan0
and the problem disappeared

Re: Unable to setup Wifi access point on raspbian stretch

I converted initially just one of my systems to Systemd. It was so convincingly solid , far more so that NetworkManager, that I converted all my Desktop / Laptop and 2 other Pi's to Systemd.

Touchscreen & SenseHat together?

I had SenseHat working great until I installed the Touchscreen and now both seem to be competing for /dev/fb0. Is here a way to have them both work together?
Message is:
raise OSError('Cannot detect %s device' % self.SENSE_HAT_FB_NAME)
OSError: Cannot detect RPi-Sense FB device

Using ctrl+?? commands to Tightvncsercer

I am running TightVNCViewer under Ubuntu 15.10 connecting to a remote Raspberry under Jessie. When running Geany on the Pi, I never had problems in the past saving changes for example by entering CTRL-S at the desktop from within TightVNCViewer. Suddenly however, this has stopped working, I have to ...

Re: Console display works but Startx Gui does not

Just hit the same thing this morning and here's how I cured it (I think): Yesterday, I installed the Raspberry LCD SCreen and had previously been running headless. Using raspi-config option 3, I changed to "start GUI at boot time" and got the following same messages after reboot in the Xorg.log see ...

Re: How to identify which RFID it is

..and to be sure that a particular reader always gets the same /dev/hidraw* allocation, you could write a UDEV rule for Debian (adapt the KERNEL, idVendor & idProduct values according to your 'lsusb' output. KERNEL=="hidraw*", ATTRS{idVendor}=="1da8", ATTRS{idProduct}=="1301", SYMLINK+="mirror", MOD...

Re: How to identify which RFID it is

I am now a little further along the line and am considering the following approach: Python reads USB / hidraw devices by polling, which means that multiple RFID readers load the RasPi so much that it cannot do anything else much. Additionally how do you identify from which of the XX devices the inpu...

Preparation of SD cards for the image

I had no problems creating a loadable SD image using the April release but the August Wheezy makes immense problems. Every time I write a Wheezy image (with Ubuntu Debian 12.10 using "dd" or Imagewriter ), the load hangs at RPi boot. Looking at the card using gdisk I can see that the GPT at the fron...
