4 thoughts on - Percent Bar On Screen – For 2 Seconds
Is it a laptop, running on batteries?
I have a configuration with a laptop with an external monitor attached, while the laptop’s monitor is off. When the laptop is running on batteries (don’t ask me why), the system power manager tries to readjust the screen brightness (I guess in order to honor the power settings in KDE), fails (since LVDS is off, or since VGA
doesn’t support brightness changes, or otherwise), then tries again a few minutes later, repeatedly. Once AC power is turned on, it stops trying.
The horizontal percent bar flashing up is a notification of the brightness level changing, during each power manager’s attempt at it.
If you use the appropriate keyboard control combination on the laptop to change the screen brightness, you can probably trigger the percent bar manually. It is similar to changing the audio volume, and other percentage bars.
This hasn’t annoyed me enough (yet) to get me to look into what’s causing it or how to fix it. It doesn’t happen when the laptop is on AC power. It might be a simple matter of configuring it appropriately in systemsettings power management controls, but I never bothered…
Or maybe your problem is caused by something else… :-)
HTH, :-)

It is a desktop. On another system, a laptop, it was happening also. I’ll check the brightness settings.
Thanks,

In Settings/Energy Saving there is a Dim Display option that was checked to happen after 25 minutes. I deselected that. I’ll see what happens now….

This seems to have done the job.
