I have a macbook 8.1 with ubuntu 12.04 installed. But my cpu is getting very hot.
On Mac my CPU is 50-60°C warm. But on ubuntu my mac is getting very hot and is by about 60°C but with min 3000rpm instead of 2000 on mac and the fan is getting very loud with 4500rpm on ubuntu when im browsing (without flash) or doing something else.
i set it to 3000rpm because it is not getting so noisy instead of 2000rpm minimum.
But thats not that what im expected.
What ive done:
i installed lm-sensors to see the temperatures and started the sensors-detect
i installed macfancld, jupiter, the newest drivers from x-updates and installed the i965-va-driver
oh and i installed mesa – with the default version my sandbridge was displayed as unknown
i added GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force drm.vblankoffdelay=1 pcie_aspm=force drm.vblankoffdelay=1 i915.semaphores=1 i915.i915_enable_rc6=1 i915.i915_enable_fbc=1"
ive added rfkill block bluetooth to /etc/rc.local to switch of bluetooth by default on boot
my mac is not as noisy as before but it is noisy and sometimes very hot
i hope you can help me
