Similar problem here with a Dell Inspiron 9200 with ATI graphics, and it's about the same story as others above: The laptop's fan is on as long as the machine is awake, regardless of total CPU load (which is usually negligible), and the battery life seems unusually short (I'm down to half charge in less than an hour). Battery life was considerably better under Karmic (a full charge was good for 3-4 hours).
For me, this regression is the result of an upgrade from Karmic to Lucid via Synaptic, rather than a full re-install. I had to use the instructions at http://news.softpedia.com/news/How-to-Fix-the-Big-and- Ugly-Plymouth-Logo-in-Ubuntu-10-04-140810.shtml to fix the bootsplash that broke during the upgrade. That How-To happens to include the "nomodeset" boot option, which fixes resume-from-suspend for me as well (Lucid fails to turn the backlight back on otherwise). I mention these in case there is some connection between those settings and the power consumption issue. I am running the regular open-source "radeon" driver, and "Hardware Drivers" gives me no option to install any other drivers (of any kind). -- [ATI Graphics][Lucid] laptop runs hot, shorter battery life, fan always on https://bugs.launchpad.net/bugs/563156 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
