I have a persistent Ubuntu Live 13.04 install on a 16 GB standard USB 2 drive that I use to carry my files and programs around to boot from Windows computers.
Originally I had used Unetbootin to use it and it worked perfectly, until I added the casper-rw partition for persistence and got BusyBox errors on boot.
Here's the problem: I wiped the drive and re-installed Ubuntu Live using USB Startup Disk Creator and modified it to boot directly to a Live session rather than an installer prompt.
I noticed immediately that the Desktop, although it shows my wallpapers and such, does not display anything from the ~/Desktop folder, does not enable me to right-click for options on the desktop, or click-and-drag anything.
Furthermore, when I minimize all of my windows, the last active window to be minimized (after minimizing this window, I would have a blank desktop), would cause the system to latch up for a while, which I could restore with Alt-F2 several times.
This happened with a clean install of raring, and when the Desktop becomes the only "active" program on the screen, it does not show text or menu options in the top left corner like it does when I launch Firefox or LibreOffice.
Is this an issue with a 64-bit install? My Unetbootin setup was 32-bit, I believe, but my computer is capable of handling 64-bit (I'm positive on this).
A dysfunctional desktop also results in a laggy experience after bootup. Although, even in Firefox, it seems like everything freezes more often than my Unetbootin setup! Why is this and how can I fix the Desktop?
