------- Comment #2 from [EMAIL PROTECTED] 2008-02-10 17:45 -------
Sporadic comments coming in seem to indicate that Fujitsu have a number of
different incompatible methods of controlling LCD brightness. The current
Fujitsu laptop module works for the S702x lifebook series and a handful of
others. Particularly on newer laptops it seems that while the "Fujitsu 02B1"
device is still physically present (and providing some functionality), control
of the LCD brightness has been moved to something else. The presence of the
02B1 device is the reason why the fujitsu module loads and appears to work
while not actually affecting the LCD brightness.
I will see if I can work out a way of identifying laptops which use the 02B1
for brightness control so the module only loads for those machines. However,
this may be complicated by the fact that I don't have a machines for which this
module doesn't work.
An interim fix may be to change the configuration item help text to explicitly
mention all machines for which we know it does work, rather than being generic.
Thoughts?
