If you like to work with your laptop running Ubuntu nearby, you may object to the way Ubuntu likes to dim the screen after a few minutes, even when the laptop is plugged in. In Windows, you'd go poking around in the screen-saver settings to find this. In Ubuntu, look in Power Settings instead. System → Preferences → Power Management. Under the "On AC Power" tab, look at "Put display to sleep when inactive for:" Moving the slider control all the way to the right yields "Never."
Also look at System → Preferences → Screen Saver. What do we have here? Another setting that can blank the screen. This is set to "Regard the computer as idle after:" and the slider is set for ten minutes.On my laptop with Nvidia graphics, the sceensaver never reaches a completely blank screen. It has a noticeable dark blue cast when the screen saver is responsible for the dimming.
I've also heard that the setting in Power Management is not working in the Netbook Remix version yet.
Is this your first visit to Bright Hub? We have a vibrant, busy Linux Channel here, and everything is not written for folks who are already experts. I, in fact, have just returned to running Linux after a six year hiatus, and I'm documenting my experiences in articles and in this blog.
Please free free to visit the main Channel articles listing page to see what's new and, if you like, please subscribe to the RSS feed to remain appraised of the latest topics.
