software failes to run, in x

[needee]

OS Suse 10
defult runlevel is 3
default desktop is kde
X/KDE was working fine, and I can use any software(frefox, evolution etc), but today When I startx, I got the following error messages, on tty1(ctrl+Alt+F1)
#startx
(SoftwareUpdater:5303): GdkPixbuf-WARNING **: Cannot open pixbuf loader module file '/etc/opt/gnome/gtk-2.0/gdk-pixbuf.loaders': No such file or directory
(SoftwareUpdater:5454): Gtk-CRITICAL **: gtk_image_get_pixbuf: assertion `image->storage_type == GTK_IMAGE_PIXBUF || image->storage_type == GTK_IMAGE_EMPTY' failed
konsole: WARNING: Unable to use /opt/kde3/share/apps/konsole/mc.desktop
konsole: WARNING: Unable to use /opt/kde3/share/apps/konsole/sumc.desktop
KNotify:layTimeout

Ok, now the prblm is that when i try to execute firefox, or evolution, ethereal(gui), any pdf doc, nothing happens, e.g, if i try to execute firefox, nothing hapens, but receive the following messages on tty1(ctrl+Alt+F1)

issue resolved... the cause of the prblm was absence of "kde 3" and "gnome" directories.

infact somehow( i dont know how.... strange) the "gnome" and "kde3" directories under /etc/opt/ were deleted.
I simply copy the two directories from another another machine, and then run
#SuSEconfig
I dont know either SuSEconfig is required or not, but before starting x, I simply run the susconfig(after copying the two directories).
