fadeout effect on displaying the logout dialog box looks bad

.

Thanks for your bug report. Forwarded the issue to the patch authors: http://bugzilla.gnome.org/show_bug.cgi?id=140717

Ryan, I'm not sure if that's possible to do a rocking effect without using composite, etc. The current one may have weird colors but he's smoother than the previous one. If you have a better way to do that patches are welcome :)

I don't understand why lowering the brightness has to produce any strage effects. I have a 24bit display and, for example, turning the bightness down on a truecolour image in GIMP would surely not produce strange effects like this.

If you have a patch that does that you are welcome to attach it ... :) The theory is easy, getting some code working is not the same story apparently, most of the software effects are slow or "laggy"...

What about using the same method for fading as the gksu package does?

When showing the gksudo dialog, the fading is smooth enough and the colours of the background image are ok.

I agree. gksudo is quite fine (I don't get the bug).

Just a quick note:

Quoting the upstream bug:

"When logging out of gnome the fadeout is often
choppy and gives users a bad impression gnome's
performance charateristics."

I don't think getting psychedelic colours every time you log out of GNOME gives a better impression of GNOME...

This is even quite noticeable with the default Dapper background, at least on my system. I don't know if that's driver-dependent -I've got an nvidia graphics card using the nvidia driver.

Anyway, that's not a rant or anything, just trying to get some extra polish for this great distro. Kudos for the developer who submitted the patch, but it is still not working properly IMHO. The impression that you get when you log out of ubuntu is that the OS is somehow unfinished or not very professional. And yes, I know we are still beta...

hmph! if you're gonna be keeping track of things like 'karma', then you need to make sure to mark later bug reports as duplicates of earlier ones, and not vice-versa. i loose karma for filing a legit bug report, and the guy who doesn't bother to check for a duplicate gets my credit! :P

Karma pimping is irrelevant. Generally, bugs with less information are
marked as dupicates of bugs with more information.

you mean i don't win a fabulous prize?

Marked as duplicate of #12389, which is linked to the same upstream bug, was reported earlier and had more activity.
