I just did the upgrade to Lucid and immediately started having this problem. Whenever a power profile is set in a KDE session (log in, plugin/unplug, manual changing, etc.), the screen dims to 0%. I have adjusted all available relevant settings in the Power Management plasmoid, tried every different profile, and created a new profile. Any ideas on what's going wrong?
