    Unhappy Definitive solution to screen blanking 12.10 x64

    Can someone help with the problem of screen blanking in Ubuntu 12.10. I have set 'Turn screen off when inactive for' to never and in order to use my system (desktop) effectively, I have used the advice given in Ask Ubuntu, Disable blank screen in 12.04 i.e.

    xset -dpms s off s noblank s 0 0 s noexpose

    this however only works for a session and I have to go through the same thing again each time I start up. Seems mighty strange that an OS has a setting that doesn't work. I am new to Ubuntu so can I have any advice or instructions in clear terms. Do not assume I know anything about the file system or anything else.

    Thank you.

    I put the 'xset s 0 0' at the end of /etc/profile so it gets run at every login. Solved the problem for me.

    gksudo gedit /etc/profile
    provide the proper password, scroll to the end of the file, add the line, save, exit

    next login should not blank screen
