Stop the cursor blinking

I’ve nothing against a blinking cursor myself but some find it distract-
ing. To stop Ubuntu’s block blinking, open gconf-editor and navigate
to /desktop/gnome/interface and remove the check from cursor_blink. The
log out and back in again. Note that Evolution appears to ignore this
setting, but most other applications will now have a still cursor.
Alternatively by changing the value in cursor_blink_time, you can simply
make it blink more slowly. A value of 5000 equates to fives seconds–
each unit is 1ms. Be aware that a setting such as 5000 means that the
cursor will be visible for five seconds at a time and then invisible for the
same length of time...
