Found this explanation and solution on the Internet: ... lm-sensors appears to have stopped working in Ubuntu Karmic Koala (basically for any distro running Kernel 2.6.31). If you look at your Kernel messages, you will see something like this:
ACPI: I/O resource it87 [0x295-0x296] conflicts with ACPI region IP__ [0x295-0x296] ACPI: Device needs an ACPI driver If you want to restore the old behaviour (which might be dangerous) add: "acpi_enforce_resources=lax" to the kernel cmdline when booting (or add it in grub.conf to make this permanent). To add acpi_enforce_resources=lax to your Grub, in Ubuntu Karmic, 1.press Alt + F2, and enter: gksu gedit /etc/default/grub 2. And enter the following line: GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax" 3. Then save the file. 4. Run this in console: sudo update-grub2 This is copy/pasted from the following link(it is missing step 4): http://www.webupd8.org/2009/10/make-lm-sensors-work-in-ubuntu-karmic.html -- lm-sensors don't work https://bugs.launchpad.net/bugs/478762 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
