xubuntu - screen brightness dims after screensaver initializes

[Brittany Dunlap]

Xubuntu 8.10, all updates applied.

After the screen saver has initialized and I come back from being away, the screen brightness is dimmed considerably. Xbacklight doesn't work and fn+right arrow is buggy.

Fn+right arrow which controls screen brightness on my laptop does not work properly, if repeatedly tapping the right arrow (fast) it seems to get confused and the brightness goes up and down fast in succession. It does work if done slowly. If I hold down fn+right arrow the brightness does go to full light. No screen representation when using the function keys like in Gnome.

xbacklight works fine after I manually put the screen at highest brightness slowly tapping fn+rightarrow.

I don't know of this is one bug or two (or more) but at least here is the base report.

Expected results:
1. Screensaver should un-dim the screen after it ends.
2. Fn key combo should not be picky as to how fast you tap the keys.
3. Xbacklight should work, it works right in Ubuntu 8.04LTS.

My laptop is an Acer Aspire 7720 (not gamer edition)
Intel 965GM
2Gig DDR2 ram
250Gig HDD

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, and GNOME has marked this bug as fixed released. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

This bug is mostly fixed. The screen brightness stays high after the
screensaver goes off, but Fn+Right/Left arrows is extremely buggy. It
flickers the screen and does not return the screen to high brightness
without a struggle.

Thanks for replying. Since the primary bug here, that screen brightness dims after screensaver initializes in xubuntu is fixed, I'll mark this as fix released. However, since the fn hotkeys are still buggy, could you check if they are still buggy in Karmic (this can be tested with a liveCD)? If they are, could you open a new report for the hotkeys? This is because they appear to be two different bugs. Thank you.
