Also affects the Toshiba Satellite L350-235 on Ubuntu 11.04 The following workaround solved both the non-functional fn+F6/F7 Display brightness keys and the auto-dim when going onto battery power, and seems to have solved the fan-always-on problem too:
1. Install lm-sensors: sudo apt-get install lm-sensors 2. Run sensors-detect which will install the 'coretemp' module: $ more /etc/modules # /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line. Lines beginning with "#" are ignored. lp rtc # Generated by sensors-detect on Tue May 10 21:00:51 2011 # Chip drivers coretemp $ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +53.0°C (crit = +114.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +50.0°C (high = +105.0°C, crit = +105.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +46.0°C (high = +105.0°C, crit = +105.0°C) 3. Modify /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux" 4. Update grub: sudo update-grub 5. Reboot your machine NOTE: The toshiba_acpi.ko kernel module will NOT load for this laptop either, but it is not required. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/321578 Title: Toshiba satellite L350/L505 fan regulation problem in Ubuntu 8.10/Ubuntu 9.10 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
