Thanks anyway though!
To restore your icons, if you can open a terminal and see it, then enter xfdesktop at the command line. Then hit Ctrl-C and exit. Your desktop icons should be restored. If it doesn't work: you must trick Xfce to let you have your icons back. If you can, go to Settings -> Desktop and change the background of the desktop to something different--a different wallpaper. Then enter xfdesktop at the command line again and see whether this works. I had a situation in LM 14 Xfce where the icons disappeared, and stayed gone after rebooting, and this is how I got them back.
You might consider configuring your xorg.conf, if you haven't already, specifying resolution and refresh rate. This isn't necessary for all displays, but can solve otherwise intractable problems on some. Are you using the proprietary ATI driver?
My desktop runs 64-bit Linux Mint XFCE, my htpc runs 64-bit Linux Mint Xfce, my secondary htpc runs 64-bit Xubuntu, my answering machine runs 64-bit windows 7, my laptop runs 64-bit Xubuntu.
