Less backlight steps after current upgrades
After upgrading to all the latest stuff, there are only 4 backlight steps using Fn-Home and Fn-End keys in my X60s Lenovo baby.
Normally, there should be 8 of them.
I have 8 while booting my machine, but after running XFCE, only 4 are left.... :-(
Any ideas folks ?
On a T61 I have 16 steps (0 to 15) all accessible under Fluxbox, and less (but bigger) under KDE or XFCE.
It seems that both KDE and XFCE make "big steps" in grouping it somehow.
But you can set it yourself in a terminal or xterm, e.g.
To know more, read /usr/src/linux-3.2.23/Documentation/laptops/thinkpad-acpi.txt
PS You can set some parameters when loading the driver, see the documentation and (as root) "modinfo thinkad-acpi" for a summary.
Is it possible to correct/patch the sources of "xfce4-power-manager-1.2.0" in order to
get those 8 steps back again ?
Seems that today's state (4 steps) is little abnormal - I never messed with acpi through the years of using Slack on my Thinkpads ...
Unfortunately I am not able to find out why the level can't be incremented or decremented by value of one.
Maybe somebody here is better at reading C code than I am, or you could ask in a xfce mailing-list or forum...
I just noticed that, as the programmer has to cope with a lot of different models of laptops, he or she tries no less than 11 kernel interfaces, fortunately all located in /sys/class/backlight.
