Sorry I was buried in work while this thread was playing out--I could have

However, I can add something else here--be careful with SD cards and
capacity.  While building up a bunch of Raspberry Pi 2 Model B 1GB cards
for internet kiosks and slideshow kiosks, I found that "8GB isn't 8GB the
world 'round".  Essentially, even from brand-name manufacturers, an 8GB--or
16, 32, 64, etc.--card from one manufacturer will differ in size.  In my
case, an EMTEC Gold 8GB card was some 200MB smaller than a Kingston 8GB
card.

200MB, you say; no big deal.  EXCEPT all the tools to manipulate SD cards
deal with raw capacity when imaging/copying.  Meaning if the destination
card is even 200MB smaller, you likely end up with a corrupted filesystem.
It should be hit-or-miss, depending on used space, but at least on the RPi
with Raspbian (a Debian fork), it _always_ was broken.

(Because of this, I became too familiar with fdisk, gparted, etc.)

G'luck,

I will watch for this. The two I have are Sandisk [16 and 64GB] and I imagine they are reputable. I just ordered 5 more "Team 16GB microSDHC Flash Card (Card Only) Model TG016G0MC28X" that Newegg has on sale, I don't know about them but it would be convenient not to have to wait while writing zeros to clear one.

Today's problem: I've installed Fedora-21 Minimal on the Raspberry Pi 2 b, that comes without an X display. After a lot of googling and trying what others suggested, something called "openbox" among other things, I can startxfce4 after logging in as bobg, the graphic login screen comes up but I loose keyboard and mouse control. Any suggestions on troubleshooting that will be appreciated.

It's a secondary problem since normally I access it via ssh from this computer and where I prefer the display, have the xfce set-up screen, xfce4-terminal, even Firefox. It all works better than I expected, at least the parts that are included in this install.

But I would like to fix the mouse and keyboard problem.

Thanks,

Bob
