Hello folks
Some people asked some questions which this tries to address.
Somebody asked if pins 2 and 4 are the right pins for their fan to be
plugged in to.
From memory pin 4 is ground but can't remember which is pin 2. Look for
the tables of GPIO pin connections on the site.
The page I wrote about getting Mate desktop going on Raspbian is
currently wrong, and I intend to fix it today.
Meanwhile here is the text of a script which will take a Raspbian Lite
image and install Mate. Careful because some of the lines will wrap in
your email client:
--snip--
#!/bin/bash
if [ `whoami` != 'root' ]; then
echo "Script must be run as root. Try sudo $0"
exit 1

# but have no video output

# Add lightdm to make script install greeter
# Without it you need to type startx to get desktop
