I've been installing and reinstalling 10.04 Kubuntu for the better part of 10 days, and each install seems to have problems the the bottom panel background. Sometimes right away, sometimes after a few boots, the bottom panel will flip over to a solid black color.

I go into K-menu -> settings -> system settings -> advanced -> desktop theme details and "panel background" appears to be set for a light color "air" background. I have to play with different selections for the panel background until the "apply" button goes active. I then press apply and the panel will turn a light color again. Sometimes it will stay a light color for a few boots, sometimes it won't. In the end, it always wants to revert to a black panel.

Is this a bug or am I doing something wrong?

That is probably a bug because i had a similar problem but after a few updates it disappeared. Did you make updates? Did you checked all the update options in you Synaptic or Adept manager?

Shutdown the machine for a bit and just booted up -- the bottom panel flipped to black again. I guess this hasn't been addressed yet.......

If you have Compiz turned on try to disable it! Maybe this will work.

Yup ... and the Nvidia proprietary driver. I'm turning off desktop effects as we speak.

[edit added] Oops. I thought I had desktop effects on, but it's off. I tried to turn it on yesterday but I did not have the Nvidia card set for hardware acceleration so KDE complained it could not turn on desktop effects at that time.

What is your KDE theme at the moment? Return your theme to default one - Air.
Compiz is a windows manager like Kwin but it is not native KDE windows manager. Mostly it is making problems with KDE.

What nVidia drivers do you have?

The theme was custom -- now set to air. The Nvidia proprietary vidio drivers are identified as "current version". No version number given.

This is a known bug with KDE 4.4.x, which is fixed in 4.5, from what I've heard. (The fix might even have been backported to 4.4.5.)

Regardless of the video card and driver, you will be affected.

For the time being, this can be used as a temporary fix: http://kubuntuforums.net/forums/index.php?topic=3110128.0
