Bug#1144923: powerdevil: when battery drops to low, brightness drops but slider in the panel stays at 100%

Package: powerdevil
Version: 4:6.7.4-1
Severity: normal
X-Debbugs-Cc: [email protected]

Dear Maintainer,


When battery level drops under the set "low level" the brightness drops to the set level but does not change the slider in the task manager panel.

After its set back at any level it works as intended.

Expected result was the change in display brightness also being present in the slider, not showing 100% while it was at 30% including the slider button position and number.

Observed result is no change whatsoever disregarding the actual brightness level.

I should also mention that the issue can be upstream since the same issue was present in fedora 44 too.

Have a good one!
