Bug#452894: ibm-acpi fault?
Adding more information,
I added ibm-acpi to my /etc/modules so my thinkpad is fully
acpi-functional and guess what? The brightness is not modified anymore!.
I suspect that without ibm-acpi, acpid or something else was
giving/reading bogus values about AC or battery and so the display kept
dimming. Right now I don't have the problem.
If the problem is the missing ibm-acpi module, how could we fix this?
Should this be considered a mistake in the way the x driver decides to
dim the screen and hence the way it's reading the info needed for this
decision? or maybe this is more a acpid or acpi-support friends bug?
