Dim when idle won't turn off

[Paul Sanders]

Binary package hint: gnome-power-manager

I am using Ubuntu 9.10 with gnome-power-manager 2.28.1. I have "Dim display when idle" turned off for both "On AC Power" and "On Battery Power".

Expected:
When I turn "Dim display when idle" off the screen should not dim.

Actual Result:
When running on the battery the screen dims after 30 seconds of inactivity.

Now I just had the screen dim on AC power also. However the interval before dimming was much longer.

Thank you for your bug report. Please run "gnome-power-manager --debug 2>&1 | tee gpm.log", let your display dim and attach the resulting file to this bug report.

[Paul Sanders (paul41)]

I ran "gnome-power-manager --debug 2>&1 | tee gpm.log" and the screen dimmed but nothing was added to the log.

[Chris Coulson (chrisccoulson)]

That's not a gnome-power-manager issue then. Is gnome-screensaver running?

[Paul Sanders (paul41)]

Yes, gnome-screensaver is running.

[Chris Coulson (chrisccoulson)]

Actually, my bad. You need to run "gnome-power-manager --verbose 2>&1 | tee gpm.log". That might explain why you saw no output before ;)

[Paul Sanders (paul41)]

Here is the log output.

[Chris Coulson (chrisccoulson)]

Does it dim even without gnome-power-manager running? Your log shows the idle state changing, but it also shows that it isn't dimming the screen on idle (it shows that the backlight is dimmed to 50% due to you being on battery)

[Paul Sanders (paul41)]

It is not dimming when gnome-power-manager is not running. The dimming when going to batter I expect and want it to do that.

This looks like a repeat of: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/392122

apt-get remove gnome-power-manager

stopped it from happening, anyway

Reporter has supplied necessary information. Thanks, Paul.

Still correct for Lucid with gnome-power-manager 2.30.0-0ubuntu1

[David Tombs (dgtombs)]

Do you mean it's still broken on Lucid?

[Juan J. Martínez (jjmartinez)]

I'm having the same problem in Lucid Netbook Edition (Acer Aspire One ZG8).

[Juan J. Martínez (jjmartinez)]

Eh, I was wrong. The problem was the screensaver. Sorry, ignore comment number 15.

[David Tombs (dgtombs)]

Can anyone else confirm that it's still broken on 10.04? Thanks.

[Paul Sanders (paul41)]

It is still a problem for me with 10.04

[David Tombs (dgtombs)]

Thanks for the update. In the future, please feel free to update the status yourself. (Normally, you aren't supposed to Confirm your own bugs, but since this one had previously been Confirmed, it's OK.)
