To the effect of, starting kubuntu, and Okular not opening PDFs automatically.
I keep an array of PDFs, a dozen or so, open on a desktop at all times.
At every system start, I get a small dialog window, for each of these PDF files, that says,
"Could not open /tmp/example.pdf".
After closing the pile of dialog windows, I then need to manually load each PDF, every time.
These files are on a FAT32 partition.
Not sure what to do so that these PDFs will load automatically every time.
