User login & lock screen monitor
 

Hello,

I use Ubuntu 11.04 with GUI.

I want to monitor my user for login/logout and lock/unlock screen.
I want to see:

• the total time I spend daily on computer: the time between first time I login or unlock screen and last time I logout or lock screen

• and the real time: total time - the time that my user was logout or screen was locked.

There is a way to do this? There is a program that can do that?
I tried who/last and to retrieve information from utmp and wtmp files, but is not quite I want.

I don't mind if I have to write this code myself, but I don't know how to catch lock/unlock screen events.

Thanks.

Hi, maybe you could find this useful:


yum install psacct


chkconfig psacct on
# /etc/init.d/psacct start

ac -p

lastcomm username

lastcomm somecommand

lastcomm pts/1

sa -u

Cheers
