Title:
Can't use the lowest brightness setting
Status in Linux:
In Progress
Status in linux package in Ubuntu:
Incomplete
Status in linux-source-2.6.22 package in Ubuntu:
Won't Fix
Bug description:
Sony TX series and possible many other Sony laptops couldn't use the lowest
brightness setting because the default sony_acpi.c restrict the lowest value
to one instead of zero. This could save some energy so the difference between
Linux and Windows isn't that high any more. I have always patched the
sony_acpi.c on my own but since this module isn't integrated in linux.source
anymore it is much more harder without recompiling the whole kernel. If there
is any Sony laptop which haven't zero as the lowest value it should be no
problem since a bug in /etc/acpi/sonybright.sh sets brightness on the lowest
option to 33 (which is out of bound 0-8) instead of zero because of spicctrl
which seems to have no impact.
Of course the /etc/acpi/sonybright.sh of the acpi-support package have to be
patched too.
