problem with Change Desktop Background

delete the file homedirectory/library/preferences/com.apple.desktop.plist and log out/in. set your background and see if it survives restarts.

Hello Redman1990 & welcome to discussions.

Try locating and deleting these two preference/plist files:

~(yourUserName)/Library/Preferences/com.apple.desktop.plist
~(yourUserName)/Library/Preferencescom.apple.preference.desktopscreeneffect.plis t

thnks but the problem have not solved.......!!
i delete the files but when i restart, i have the same Backround, again.
Then i reboot from Mac OS snow leopard disk an reset ACl settings but nothing,
the bug is there......

by the same background do you mean the default snow leopard background or the one you've set before and want to change?
try this. enter the following terminal command

open $TMPDIR/../-Caches-

this will open a new finder window with the folder -caches-. dlete the file com.apple.desktoppicture... from that folder and log out/in. then try changing the desktop pickture in system preferences again. see if it survives the restart now.

yes i mean the default backround from snow leopard
the name is Aurora

After restart i see it again....

after doing what I told you you should see the default background again. change it to what you want and restart again. does it still revert to the aurora background?
