backlight module is "delayed" #2367
Description
Checklist
- I have read the appropriate section in the contributing
guidelines - I believe this issue is a problem with polybar itself and not a misconfiguration on my part.
- I have searched for other open and closed issues that
may have already reported this problem. - I have checked the known issues page for this problem.
Describe the bug
With the backlight module, the brightness bar is "delayed". I.e. when I first change it, the bar doesn't change, and when I change it again, the bar changes to what it was before the current change.
Expected behavior:
Backlight label/bar should change when brightness is changed
Actual behavior:
Delayed behaviour explained before
Was it working before?
- Did you also experience this bug in an earlier version of polybar (yes/no/don't know)? no
- If no, what was the last version where this worked correctly? None, I just installed it
To Reproduce
[module/backlight-acpi]
inherit = module/xbacklight
type = internal/backlight
card = amdgpu_bl0
label = %percentage%% brightness
interval = 5Change your brightness with something like this in your i3 config:
bindsym XF86MonBrightnessUp exec --no-startup-id brightnessctl s +5%
bindsym XF86MonBrightnessDown exec --no-startup-id brightnessctl s 5%-
Must have brightnessctl installed. You can also just brightnessctl s +5% or brightnessctl s 5%-.
