If you get this error trying to ping addresses:
ping: icmp open socket: Operation not permitted
Per this post, chmod ping like this and then it will work as expected.
sudo chmod u+s /bin/ping
Configuring a static IP for Raspbian/Debian Jessie
Looks like on Raspbian Jessie the way you configure a static IP has changed. You used to configure static IPs in /etc/network/interfaces, but on Jessie it looks like the file to edit is now /etc/dhcpcd.conf (per the comment at the top of the prior file).
Scroll to the end of the file and paste something like this, editing IPs to match your network:
interface eth0 static ip_address=192.168.1.xxx/24 static routers=192.168.1.xxx static domain_name_servers=8.8.8.8, 8.8.4.4
Reboot, done.
Building autogen based source on Ubuntu and derivatives
Install build tools:
sudo apt-get install build-essential
Install autogen tools:
sudo apt-get install autogen
In project source:
./autogen.sh
If you get errors like this:
configure.ac:25: error: possibly undefined macro: AC_PROG_LIBTOOL
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
autoreconf: /usr/bin/autoconf failed with exit status: 1
… then also install libtool
sudo apt-get install libtool
Then build and install as normal:
./configure
make
sudo make install
Installing latest Nvidia 361 drivers on Ubuntu / Linux Mint
I’ve posted a few times about installing the nvidia-304 legacy drivers on Linux Mint, which I’ve been using on an HP desktop which has nvidia 6150 graphics on the motherboard.
I just upgraded to a shiny new geforce 750ti card which runs in this same HP, powered through the PCI-E slot so and doesn’t need any additional power (which would have required ugrading the PSU too).
To upgrade my nvidia drivers in Linux Mint, it seems the latest 361 drivers are not available in the main apt-get repos, and even if you add a ppa, it seems they’re not there yet either. Luckily, to install from the download on the nvidia site it’s pretty easy.
To summarize the steps I took based on the instructions here:
- remove the current nvidia drivers:
sudo apt-get purge nvidia* - kill the current Mint DM:
sudo service mdm stop - sudo the driver .run executable downloaded from the nvidia site.. chmod +x it if needed. Reboot, and done! Running the latest drivers!
