Jesse Xfce wallpaper stuck
debian-user:
I have a Dell Inspiron E1505/6400 laptop with Debian and Xfce.  I am 
running an external monitor:

Currently, the desktop wallpaper is improperly tiled and stuck:
1.  The default Debian 8 wallpaper appears (1024x768) in the upper left 
portion of the my 1920x1080 monitor, and portions of the same image 
appear to the right, below, and in the lower right corner.
2.  If I go to Applications Menu -> Settings -> Desktop -> Background 
and choose a different image, tiling, etc., the desktop wallpaper stays 
the same.
Searching /var/log for 'xfce', I see an endless stream of error messages:

My laptop has Intel GM945 chipset graphics, not NVIDIA.
/var/log/dmesg is of no help:
2017-04-04 19:13:56 root@jesse ~
# cat /var/log/dmesg
(Nothing has been logged yet.)
2017-04-04 19:13:58 root@jesse ~
# ll /var/log/dmesg
-rw-r----- 1 root adm 31 2017/02/21 21:52:40 /var/log/dmesg
Any suggestions for troubleshooting this?
