Unable to select own desktop background in Ubuntu

Hi,

I've installed Ubuntu 8.04LTS (64-bit) recently and something I've noticed is that I am unable to change the desktop background to anything else besides the 3 or 4 backgrounds that comes pre-loaded.

When I go into the menus for adding a new background, I can view the pictures but as soon as I choose to add it as a background nothing happens and I am back to main menu for changing the background with the 3 or 4 standard Ubuntu backgrounds.

Any help would be appreciated.

They were my own images. jpeg There are a couple that comes with Ubuntu that also doesn't want to load. Space ones.

Hi thanks for the reply. I am able to save files to my desktop and move them around from the Desktop to Documents etc. I am considering formatting the HD and re-installing everything since my graphics card drivers have also stopped working after I installed virtualbox. No more 3d desktop effects for me either at the moment. Maybe the easiest option would be to re-install. I don't have alot of data/programs on the installation at the moment. Thanks for the help.

Hi audiovoodoo, thanks for the reply. I can't remember the exact message on the graphics card issue but whenever I went into the XServer settings it said something about the Xserver drivers not being loaded or running. And that I should run nvidia-xconfig to fix it. That didn't help.I did try a couple of things like re-installing all the drivers and un-installing virtualbox and compiz.Also enabled and disabled the restricted drivers without any success.My MB has an integrated GPU (Nvidia 6200) and I wonder if that wasn't clashing with the 8800GT that I have installed. My Linux skills are very limited but I am going to give it another try.I really enjoy the cube effects and the 3-D desktop. I am going to format and try get everything going again. :-)

No problem I've re-installed Ubuntu 8.04 64-bit tonight and managed to get everything set up the way it was before. All my desktop effects are back including the 3-d cube.(I lost it when I installed virtualbox). Don't think I will be trying to install it again any time soon! Most importantly I am able to select my own backgrounds now. I appreciate your help on this.
