dim dispay when idle (power management)

[AndreK]

If "dim display when idle" is enabled, and the display's intensity is manually set (using Fn+keys) to dimmed, AND computer is idle, then Ubuntu dims it a litle bit more, but whhen computer is used again, it does not restore the dimmed level, but instead increases brightness a lot.

I just purchase my first dell (inspiron 1525 pre-installed w/ Ubuntu) and I am also experiencing this behavior. However, I notice one additional aspect of this glitch: I always keep the laptop plugged into its power supply. If I adjust the screen intensity to a lower level of intensity, it will remain at the level I've chosen for a random period of time, then it will reset itself back to maximum intensity.

Since it's been a very long time since any additional info was added to this bug, I'm just checking to see if this is still an issue, and find out what additional work should be done on this bug.

[AndreK (andre-k)]

the problem remains in Ubuntu 8.10
it may be a little different:
display is not dimmed (backlit intensity not changed) nor with external power, or when on battery.

additional info:
Backlit intensity is controllable via hotkeys, but the animated bar has different amount of steps than the electronic controller, so the "progress bar" proceeds several steps after the maximum intensity is reached.

Also, the selected intensity is *not* saved on logoff/shutdown and restored on login.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

[AndreK (andre-k)]

it's not a problem anymore on my laptop +updated 9.10beta - thank you.
also verified on a IBM T60

it still doesn't work right in Karmic on my Lenovo R61. The manually set brightness is not restored after dimming.
