[Kernel-packages] [Bug 570589] Re: Lucid: Overheating due to no PM for ATI KMS
The currently under-development Ubuntu 14.04 Trusty Tahr is based on the 3.13 kernel. You can download a pre-release version at http://cdimage.ubuntu.com/daily-live/current/ and the final release is scheduled for April 17th, 2014 as per https://wiki.ubuntu.com/TrustyTahr/ReleaseSchedule -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/570589 Title: Lucid: Overheating due to no PM for ATI KMS Status in “linux” package in Ubuntu: Fix Released Bug description: As you know the code in Lucid's -32 kernel doesn't have support for power management on ATI cards with KMS (which is default). This is not a problem for desktop users, but laptop users with beefy cards may run into severe overheating issues. I expect the forums to flood with these problems once lucid is final.

[Kernel-packages] [Bug 570589] Re: Lucid: Overheating due to no PM for ATI KMS
I've just tested the new kernel, and it seems to work well in the sense that it keeps my laptop at around 60°C when idle. The problem is that, even at 60°C, my laptop fan is still very noisy. Is 60°C still too hot?

Julien - poor hardware design is a possibility. Also make sure you have removed all dust from inside the computer, particulary from the CPU and GPU fans and heatsinks (if it's a desktop, open the case, if it's a laptop at the very least run a vacuum cleaner nozzle along the external air vents). You can also put the edge of a book under the back edge of your laptop so that it is raised off the desk at a slight angle, or purchase a laptop cooling pad (with USB powered fans) to sit the laptop on. I neglected to mention that to use the new power management feature on R700 and newer hardware (other than APUs) requires installation of the latest AMD graphics microcode (ucode) files to /lib/firmware/radeon These are available at http://people.freedesktop.org/~agd5f/radeon_ucode/ Get the version ending in smc. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/570589 Title: Lucid: Overheating due to no PM for ATI KMS Status in “linux” package in Ubuntu: Fix Committed Bug description: As you know the code in Lucid's -32 kernel doesn't have support for power management on ATI cards with KMS (which is default).
