I don't think this made it to the list. sorry if this is a repeat. I tested 2.6.10 and had the same problem. So it seems this version is where the change/problem first appeared. All the tested kernels, including the working and non-working, use the same Toshiba ACPI Extras version, 0.18. I only guess that the new entry (after using the command that previously turned the lcd backlight off) in the non-working 2.6.11->2.6.12-rc2 kernel logs (video bus notify) is something to investigate. I also enabled the CONFIG_ACPI_DEBUG option and retested the kernels with no luck. klug wrote: > I tested 2.6.12-rc2 with the same results.
