Description Vianney Carel 2012-09-07 22:07:05 UTC

The screen brightness is reset to its max value every time I log in.

It looks like a regression, because on kde 4.8, I didn't have that behaviour. My current brightness setting was preserved during login.

Please not that in the system settings, in energy management, I disabled the brightness control under all modes.

Reproducible: Always

Steps to Reproduce:
0. Uncheck the britghness checkboxes in the energy managemnt
1. Start the computer, and wait for the login screen
2. Lower the brightness
3. Log in
Actual Results:  
Brigthness is set to max.

Expected Results:  
Brightness shouldn't change.

Maybe it's related... : when my laptop is mains powered, the brightness doesn't seem change when I log in.

And when i'm on battery, the brigthness sometimes comes back to 100% when I enable the setting for dimming the screen after a time of inactivity.

This is marked as 'NEEDSINFO', can someone clarify what info is needed?

I dont' think this report is set to the correct status.

Comment 6 Nate Graham 2018-03-11 21:28:26 UTC

Can't reproduce in Plasma 5.13.3: If I set the brightness to some arbitrary level, uncheck the Brightness checkboxes in Powerdevil, and then reboot, the system come up at whatever brightness level it had when I rebooted it.
