Hi Christopher,

ORIGINAL BUG SUMMARY:
As you'll remember I reported a bug for the XFCE desktop (Xubuntu 14.04LTS).
[1] On one box (Xubuntu 14.04LTS amd64) with a dual screen setup it was not possible to place icons on the right hand screen. Icons wouldn't "stick" and return to their original prosition on the left hand screen.
[2] All our boxes (2 Xubuntu 14.04LTS amd64 and 1 Xubuntu 14.04LTS i386, 3.13.0.46) started resetting the specific icon placement on the desktop about a month ago. This means that, if the user placed icons on a specific location on the desktop, after a reboot, the icon location changed. Often all icons were placed to the "left hand default position", however, sometimes some, but not all were returned to a complete left hand default position.
The uname -a info of all boxes are:
The i386 install - Linux minipussy 3.13.0-46-generic #77-Ubuntu SMP Mon Mar 2 18:26:13 UTC 2015 i686 i686 i686 GNU/Linux
The amd64 single screen install - Linux PUSSYcomputer 3.13.0-46-generic #77-Ubuntu SMP Mon Mar 2 18:23:39 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
The amd64 dual screen install - Linux HAL9000X 3.13.0-46-generic #77-Ubuntu SMP Mon Mar 2 18:23:39 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

METHOD:
You asked me to check whether the daily versions also showed the same behaviour. Hence, I downloaded the daily/ current version of Xubuntu 14.04LTS, following the link you sent me. I installed them on a LiveUSB, using Unetbootin, and check for similar behaviour as I described above.
After installing, I left everything in default except:
---    Changed my keyboard layout with Settings Manager
---    Changed the default icons on the desktop (e.g.home, system drives) to create a clean playing field.
---    Added the Action Buttons to the top panel for easy shut down/ reboot.

The daily/ current versions, as retrieved following your link, and used were:
Linux xubuntu 3.16.0-30-generic #40~14.04.1-Ubuntu SMP Thu Jan 15 17:45:15 UTC 2015 i686 i686 i686 GNU/Linux

RESULTS - i386:
FYI, I made screenshots so you can see what happened. I placed files on the desktop and rebooted a couple of times.
For i386, the same behaviour was observed. However, some, but not all icons were returned to their default position. See the images
Screenshot - daily i386 before reboot.jpg
Screenshot - daily i386 after reboot.jpg

As you can see the position of some, but not all files were changed on the desktop. The files File 06 - File 08.jpg and the file Christoper (text of this message) were moved to a default left hand position.
When the files were placed back to their original position (i.e. Screenshot - Daily i386 before reboot), a new reboot again changed the position of these files, placing them again on a left hand default position. Hence, this behaviour is reproduceable and consistent.

Additional note 01: when moving the images (e.g. File 05 hanging.jpg,
File 07.jpg) the cursor appearance changed. Could unfortunately not make
a screenshot of it. It turned into 2 cursors/ arrows and a part of the
image. This happened ONLY when moving the image files. The original
(proper) appearance returned when for example placing the cursor
somewhere in this text.

Additional note 02: I quickly took a look in -/.config/xfce4/desktop
during all this. Contrary to the installs on our production machines,
this daily version DOES NOT create multiple icons.screen0-***.rc files.
All through the process there was just one file on this location.

RESULTS - amd64 - single screen setup
Repeated the methodology as I described for the i386 install. However, this is a single screen set up (1280x800 laptop, amd64 install).
Results were identical to the results with the i386 install. See images
Screenshot - daily amd64 single screen before reboot.jpg
Screenshot - daily amd64 single screen after reboot.jpg
Again, this daily version DOES NOT create multiple icons.screen0-***.rc files. All through the process there was just one file on this location. The cursor change when moving a image file did not occur with this install.

RESULTS - amd64 - dual screen setup
This was done with a fresh LiveUSB install, not the same as used with the amd64 single screen box. I did do some additional settings of course, using the Display settings to disable the Mirror Screens setup and to place one screen right of the other. This is the only additional setting I did compared to the other 2 checks I did before.
Again, I placed the icons as the previous tests. See image
Screenshot - daily amd64 dual screen before reboot.jpg

Surprisingly, I was not able to duplicate the reset to default left hand side behaviour as with the previous 1386 and amd64 single screen set ups. In the 10 or so reboots I did, some times changing the position of the files on the desktop around, or creating and then deleting one, the position of the remaining files stayed as set originally.
I did find multiple icons.screen0*.rc files though:
xubuntu@xubuntu:~$ cd ~/.config/xfce4/desktop
xubuntu@xubuntu:~/.config/xfce4/desktop$ ls -ahl
total 16K
drwx------ 2 xubuntu xubuntu 4.0K Mar 11 10:45 .
drwxrwxr-x 6 xubuntu xubuntu 4.0K Mar 11 10:37 ..
-rw-rw-r-- 1 xubuntu xubuntu  437 Mar 11 10:27 icons.screen0-1904x1039.rc
-rw-rw-r-- 1 xubuntu xubuntu  834 Mar 11 10:45 icons.screen0-3824x1039.rc

Furthermore, I found with this install too, as with my "production
install", that it is impossible to place files/ icons on the right hand
screen. I installed Recordmydesktop and added the resulting clip to the
attached files for your information (i.e. No placement possible
RHscreen.mkv).

ADDITIONAL:
Finally, acting on a hunch, I finally played around with the amd64 dual screen install. In the past, I've been able to place icons/ files on the right hand screen, and this was after I deleted the icons.screen0-*.rc files in ~/.config/xfce4/desktop. As expected on the next reboot, all icons/ files on the desktop were reset to the left hand default position, but moving them, it proved possible to place them on the right hand desktop. However, after an additional reboot, they were placed at the left hand default position again. Placement on the right screen desktop was no longer possible (as in No placement possible Rhscreen.mkv). Looking in ~/.config/xfce4/desktop then showed that new  icons.screen0-*.rc files were created. At that time, I also tried looking the  icons.screen0-*.rc files (sudo chattr +i ~/.config/xfce4/desktop/icons*) but this had no effect, resulting in new  icons.screen0-*.rc files being created and icons being reset to the left hand default position.

Trying to recreate this I:
--- deleted icons.screen0-1904x1039.rc
 and rebooted.
--- It was not possible to place icons/ files on the right hand screen desktop.
--- Subsequently, I deleted icons.screen0-3824x1039.rc. Now no files were present any more in ~/.config/xfce4/desktop. Upon reboot, as expected, all icons/ files were reset to their left hand default position. However, it was not possible to place icons/ files on the right hand screen desktop.

Christopher, I hope this helps you solving this mystery. If I can help
you any further, please don't hesitate to drop me a line!

Kind regards,

Natalia

Title:
  Unable to drop/ place files and links on second screen in dual screen
  set up

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  After updating from Xubuntu 13.10 (amd64) to Xubuntu 14.04 LTS (amd64)
  I have encountered a bug with my dual screen set up.

  Running the XOrg screen driver (xserver-xorg-video-nouveau), it is
  possible to place/ drag and drop files and links on my left screen
  desktop. This is also the desktop that contains the system icons (e.g.
  removable drives, rubbish bin).

  However, I I try to drag and drop a file or link on the right screen
  desktop, it will not "stick" and "fly back" to its original location
  on the left screen. Additionally, I noticed that, when dragging the
  file over the troubled desktop, the "placement squares" don't show up.
  They do on the functioning left screen.

  Although I have a NVIDIA Corporation GK107 [GeForce GTX 650] Geforce I
  do run the XOrg driver since it gives me the best results with the
  software I'm using frequently. However, when I tested this during my
  initial install of Trusty, I noticed that I did not encounter this bug
  with the proprietary NVidia 304.117 driver (331.38 did not work for me
  at all). Running the NVidia 304.117 driver, it was possible to drag
  and drop/ place files and links on both screen desktops. Also the
  "placement squares" appeared on both screens when a file was dragged
  over it.

  After returning to the XOrg driver, the problem reoccurred, and
  placement on the right screen was again not possible.
