Thread: Power management doesnt work after video driver update

    Default Power management doesnt work after video driver update

    I have a HP Pavillion laptop running oS 12.3.
    I recently updated the ATI video driver (changed to fglrx, before I was using radeon) and now the power management system doesnt work properly anymore.
    After a few minutes of inactivity, it reduces the monitor brightness to 50%, then 10% and after that it should turn the screen off, as it use to do before the update.
    But now, after going to 10% it just goes back to 100% brightness.
    When I manually try to turn the monitor off with xset dpms force off it does work.
    Any advice on how to solve this?

    Well,
    I managed to make it work.
    So in order to maybe help others with this issue:
    yesterday I installed the laptop-mode-tools and the fglrx_xpic_SUSE123 (32bit) packages and I did aticonfig --initial --input=/etc/X11/xorg.conf
    Today when I logged in the power management was working again.
    Don't know what exactly resolved the problem so whatever.
