Stopping the network manager and applet from running in Ubuntu Cinnamon

Cinnamon 2.2.13
Ubuntu 14.04

# do not start network manager

echo manual > /etc/init/network-manager.override


# remove network manager applet from cinnamon dock panel

vi /usr/share/cinnamon-session/sessions/cinnamon.session

#RequiredComponents=cinnamon;cinnamon-settings-daemon;cinnamon-screensaver;nemo-autostart;nm-applet;
RequiredComponents=cinnamon;cinnamon-settings-daemon;cinnamon-screensaver;nemo-autostart;

# reboot

Mapping ATA device numbers to hard drive device names on Ubuntu

A nice little one liner:

# ls -l /sys/block/sd* | sed 's/.*\(sd.*\) -.*\(host.*\)\/t.*/\2 => \1/'

host0 => sda

host1 => sdb

host6 => sdc

host7 => sdd

host8 => sde

host9 => sdf

therefore

host0 => ata0 => sda

Which is the same with this: 

The first number in the [] brackets shows the ata number

# lsscsi --long

Lenovo z710 - double suspend issue on Ubuntu 13.10

My z710 when suspended after a lid close, would un-suspend when the lid opened and then after 5 secs re-suspend itself.

Fix for this was to turn off the logind.conf settings and allow acpid to do all the work

vi /etc/systemd/logind.conf


#ignore all and use acpid instead
HandlePowerKey=ignore
HandleSuspendKey=ignore
HandleHibernateKey=ignore
HandleLidSwitch=ignore

SuspendKeyIgnoreInhibited=no

Found this by uncompressing the firmware and running 'strings' over it.
Couldn't find it in the Draytek telnet command reference guide.
