I run a 2.6.37.6 kernel on a Toshiba Satellite Pro L770-116 Notebook with an American Megatrends BIOS (Aptio Setup Utility). I read that Toshibas with Phoenix BIOS are treated differently from the ones with a Toshiba BIOS, with different kernel modules being necessary (the toshiba_acpi module is not appropriate for my laptop ('no such device'). However, I could not find any information on Toshiba Laptops with an AMI BIOS. The only Toshiba-specific module that's being loaded is toshiba_bluetooth. Some ACPI features do work like e.g. the fan control, and toggling the state of the internal WLAN card with Fn-F8. When I enter acpi -V, there's a line saying: Cooling 0: LCD 6 of 7 I noticed that I can alter the value of 'Cooling 0: LCD 6 of 7' with Fn-F6/Fn-F7, but the brightness of the display does not change accordingly. Fn-F3 and closing the lid crashes the system completely, enabling the VGA port output does not seem to work, Fn-ESC displays a symbol for muting toggled but it has no actual effect on the sound output. I tried to manually load omnibook kernel module, as some pages suggested it supports Toshibas with non-Toshiba BIOSes, but it does not seem to do so and gives kernel error messages (omnibook: Unknown model). I would be glad to provide additional information that might be needed by module developers to add support for the ACPI functions of the Toshiba Satellite Pro L770-116. I read that Toshiba may provide information for Linux developers too [1], which at least *sounds* good.
