Getting server to boot to terminal by default
Having problems with usb connection dropping every 1 to 2 days for connected weather station, which then requires a reboot to fix.
Looking at running server headless to reduce resources used.
To achieve this edit:
/etc/default/grub
put “text” into the line:
GRUB_CMLDLINE_LINUX_DEFAULT="text"
Restart Grub:
sudo update-grub reboot
udisks automounting is running apparently as part of gnome.. no gnome - no automounting
Fix 1) is to use udisks-glue
sudo apt-get install usbmount udisks udisks-glue
git clone https://gist.github.com/5399914.git udisks-glue #(or copy and paste if you don't like git) cd udisks-glue chmod +x udisks-glue sudo cp udisks-glue /etc/init.d/. sudo update-rc.d udisks-glue defaults
wireless connection problems
Having major problems with the wireless connection. Wireless card can be found from command:
lspci | grep Network
Atheros AR9285
has not good reception of signal - 2-3 bars from 5, but problem is that it drops this signal periodically and also has high packet loss.
Followed some instructions at www.xors.me/?p=1069 to install some driver - but I still have problems
Seeing some strange loop for wlan running in syslog

This seems to be running constantly - and presumably crashes out every so often because of some small variation in Wifi signal strength and then has some issues reconnecting.
What is the purpose of this ?
