Created attachment 4912 fix brightness popup with /xfce4-power-manager/change-brightness-on-key-events=false In order to fix brightness change steps on my thinkpad x200s, I added the property /xfce4-power-manager/change-brightness-on-key-events to xfconf: xfconf-query -c xfce4-power-manager \ -p /xfce4-power-manager/change-brightness-on-key-events \ -n -t bool -s false This works in general, but the popup's "volume bar" now always extends to the far right of the popup. Inspecting the code, I found that the "level" variable in xfpm_backlight_button_pressed_cb() is not initialized in this case. Attached patch fixes the issue.
I rebased the patch against current master and added it to https://github.com/b1-systems/for-upstream-xfce4-power-manager.git branch "brightness-popup-fix" for easier merging :-)
Thanks for this as well. Feel free to ping me if you write more patches :) Pushed to master in: http://git.xfce.org/xfce/xfce4-power-manager/commit/?id=7f4fb9c021fb80d28d2ef7dcdbd3839a39d16f99
