[Bug 730063] New: Problem with power profiles brightness slider
https://bugzilla.novell.com/show_bug.cgi?id=730063 https://bugzilla.novell.com/show_bug.cgi?id=730063#c0 Summary: Problem with power profiles brightness slider Classification: openSUSE Product: openSUSE 12.1 Version: Final Platform: i686 OS/Version: SuSE Other Status: NEW Severity: Minor Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: suddha.sourav@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux i686; rv:7.0.1) Gecko/20100101 Firefox/7.0.1 Dragging the brightness slider to its lowest settings and hitting apply does not change the brightness. However, keeping just a small gap from the lowest point makes it work. Reproducible: Always Steps to Reproduce: 1. Go to Configure Desktop (Personal Settings) > Power Management. 2. Check the power profile that is currently being used. 3. Go "Power Profiles". 4. Pick the active power profile. 5. Enable "Display Brightness" and drag to the leftmost side. 6. Hit "Apply". Actual Results: Brightness does not change. Expected Results: Brightness should have changed to the lowest value. Dragging the brightness value to a value that is slightly lower than the lowest value works as expected. I believe the lowest value is being processed improperly. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I believe that the slider's value is being passed to xbacklight, where the trouble seems to reside. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

And power control switches brightness on the DIS but not on the IGD. But again, this is only a guess. So a fix for me is: #! /bin/sh if [ -f "/var/run/powerornot.pid" ];then echo "Allready running? Found pid file, exiting"; exit 1 fi old_status="false"; while [ 1 ];do BAT=`grep on-line /proc/acpi/ac_adapter/ACAD/state` if [ -z "$BAT" ] && [ "$old_status" != "$BAT" ];then logger "Switching batterymode" echo 882 > /sys/class/backlight/intel_backlight/brightness /usr/bin/cpufreq-set -g powersave -r elif [ "$old_status" != "$BAT" ];then logger "Switching to powermode" echo `cat /sys/class/backlight/intel_backlight/max_brightness` > /sys/class/backlight/intel_backlight/brightness /usr/bin/cpufreq-set -g ondemand -r fi old_status=$BAT; sleep 1 done -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
