Laggy output on laptop battery power.

[mateuszskoczen]

Bug Report

Description

Affected module: all
Version used: latest AUR ; 2.2.0-1

Description:
When I unplug my laptop charger status bar is very laggy. Even when I set intervals and change for example brightness using media keys or scroll, I have to wait multiple seconds to see the proper value. When I use charger everything is all right.

How to reproduce

Unplug laptop charger and change f.e. brightness or volume using media keys or scroll on bar.

This rings a bell - is that a new or an older laptop? Otherwise, the system runs fine, is that true?

[mateuszskoczen]

My system is fine, laptop is about 3-4 years now.

[tobi-wan-kenobi]

I suspect it might somehow be related to speed stepping, but I have no idea how to even reproduce this.

Would you be wiling to try a debug binary?

[mateuszskoczen]

If I only know how to do it, sure.

[tobi-wan-kenobi]

After reading up on possible causes a bit, I have to admit I have no idea how to troubleshoot this further.

If you restart i3 after unplugging (i3-msg restart), does it start working normally?

Also, which OS and which version of Python are you using?

[mateuszskoczen]

Arch linux 6.6.10-arch1-1 Python 3.11.6
After restart I have to wait something around 10 second to load it again and it doesn't work normally.

[tobi-wan-kenobi]

You mean it takes 10s for the bar to load?

If you start bumblebee on the commandline, does it output data normally (once per second)?

[mateuszskoczen]

1. yes
2. it doesn't show any output and gives few errors

@mateuszskoczen I have pushed a somewhat experimental change to main, so if you could update your installation to the git version of AUR, maybe the situation improves.

[mateuszskoczen]

Nothing changed

[tobi-wan-kenobi]

Sorry to take so long to get back to you. I have been thinking about this issue a lot, and have no real idea how to fix it (because I cannot reproduce it).

I have, however, come up with a possible workaround: Would a configurable "startup delay" work for you? I.e. you can set in your config "wait for 10s to actually start bumblebee", so you would not have to manually restart bumblebee. You'd just get a blank bar for a couple of seconds, and once your system is "ready", the status bar starts.

Also, do I understand it correctly that you are actually facing 2 issues:

• Unplugging the power supply makes the bar (but only the bar) really slow
• After a reboot, you need to manually restart the status bar for data to show?
