I can confirm this bug also on my card: Ati Mobility radeon HD 4500, RV710 I always had overheating problems with the opensource driver, so I used the binary driver from ATI.
Actually with the latest updates the ati-closed-driver doesn't work anymore also on ubuntu 12.04 So the only solution is to install the old LTS from Ubuntu or debian stable. I can provide additional information about my hardware and my issue. This bug was around from a lot of time right now and is potentially harmful about the hardware. Can be possible to correct the bug (at least initially) forcing the driver to "low" profile? it will be less responsive but at least it will be safe to use. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1080350 Title: CPU Overheating with ATI driver Radeon HD Mobility graphics Status in X.org XServer - ATI gfx chipset driver: Confirmed Status in “xserver-xorg-video-ati” package in Ubuntu: Confirmed Bug description: Ever since upgrading from Maverick (with GNOME Classic) to Precise (using Unity 2D since using the default Unity makes the situation worse) my note book regularly overheats with normal usage: I've been regularly using: echo low | sudo tee /sys/class/drm/card0/device/power_profile I've am also using psensor to warn me if the temperature rises above 92°. When 'idle' the temperature is at about 80°. If the CPU is used (merely starting eclipse and letting all the the startup validation processes finish) it quickly rises to 88°. If the usages is sustained (rebuilding a java project) the temperature oscillates between 95° and 98°. If I do anything else that adds to the load (ie. if the temperature is >98° for short period of time), the system freezes, but the everything remains on, fans and CPU temperature stays up. I need to turn off the notebook by keeping the power button pressed. Note that this system overheats /with/ the low power profile.
