Powersave doesn't set the display brightness with toshiba_acpi
Last modified: 2006-02-13 10:45:27 UTC
I have a Toshiba laptop and I like to have the display brightness always set to the minimum. Here's what I have done: 1. Edited /etc/sysconfig/powersave/scheme_performance and /etc/sysconfig/powersave/scheme_powersave (these are the only two schemes I use) and set DISPLAY_BRIGHTNESS="min". 2. Ran SuSEconfig (don't know if this is strictly necessary with powersaved) The result was that the display brightness was set to the maximum, instead of to the minimum: # cat /proc/acpi/toshiba/lcd brightness: 7 brightness_levels: 8 I also tried setting DISPLAY_BRIGHTNESS to a numerical value and it didn't work either... The brightness is always set to the maximum.
@hmacht/seife: this is a issue for you
Maybe a stupid question, but does the powersave daemon adjust any display brightness at all? Can you please try to adjust the brightness manually and tell us if this works. From 'powersave -h': Brightness: -k, --set-brightness <x> set current brightness level -K, --get-brightness get current brightness level -L, --get-brightness-levels get number of brightness levels

And according to the comments in /etc/sysconfig/powersave/scheme_* it should work with «some vendor specific ACPI modules, such as ibm_acpi, asus_acpi, sony_acpi and toshiba_acpi.» > Can you please try to adjust the brightness manually and tell us if this works. Yes, it really works (I am using toshiba_acpi). jfraga@linux:~> powersave -L Available brightness levels: 8. jfraga@linux:~> powersave -k 7 Brightness level set to 7. jfraga@linux:~> powersave -k 0 Brightness level set to 0. jfraga@linux:~> powersave -K Current brightness level: 0. But the DISPLAY_BRIGHTNESS variable is ignored.
I think kpowersave is running, right? If that's the case, you have to configure kpowersave to adjust the brightness via the daemon. This is a brand new feature. I hope there is a switch to disable brightness adjustments by kpowersave, Danny?
I'll test this and then update the comments for the brightness variables like "these might get overridden by a brightness-aware powersave client like kpowersave" or something like that.

I think this is a WONTFIX then...
