According to the nvidia-settings application, my XPS M1330 idles at 40 Celsius. Even watching full screen video, it doesn't get significantly hotter than this.
I have the latest A15 BIOS installed and have the nvidia-glx driver 180.44-0ubuntu1 installed from the Jaunty repository. I set the devices section of my /etc/X11/xorg.conf file as shown below in an attempt to allow dynamic GPU scaling: Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce 8400M GS" Option "NoLogo" "True" Option "TripleBuffer" "True" Option "BackingStore" "False" Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x3333; PowerMizerLevelAC=0x3; PowerMizerLevel=0x3" Option "OnDemandVBlankInterrupts" "True" Option "Coolbits" "1" EndSection -- nvidia graphics driver 177.80 on geforce 8400 makes fan spin all the time https://bugs.launchpad.net/bugs/280805 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
