It would appear that on Jul 22, Mircea Hutanu did say:

Yes I reasoned so... but since the permissions worked as was for my
usual user account, I tried to do this with chown...

Actually I've found a workaround (see below) that seams to work for FC2
though not for the same kind of problem with my MDK 9.1 installation.
in both cases I was having what looked like permission problems when I
tried to startx with a different login than usual...

yes... the login process is part of my fc2 workaround see below. I too
would like to know why this happens. And for that matter, why my work around
works in the 1st place...

I thought so. I figure I should be able to just get a list of pathnames
that I can embed in a root script that chowns them all to the user I
currently want to designate via $1.

But tty login and startx both like to mess with them...

(how do you feel about in-line quoting like I'm using???)

Actually that was one of the first things I did... But every time either
the login process or the startx one chowned these devices it also did
something to chmod 600 $device... rendering my attempts to use group
permissions useless... <sigh>

It turns out that the relevant /dev/files are also chowned when a user
login to tty1 (at least when it's the only tty with a user logged in to a 
"run level 3" system...) 

I don't know why. But I found that if I do a clean shutdown of the x
server, then logout _all_ users, all I gotta do is log in to tty1* with the
account I want to run startx from. Then run startx BEFORE logging in any
other users. Then no mater which user I'm using. I can play my cd's with
kscd... At least, that is if I remember to actually stop the cd before I
shut down the xserver... 

* I didn't check logging in the _only_ user to any of the other tty's
so I can't say for sure that tty1 is necessary. But the below sequence
did work with tty1...

In fact I just successfully switched back in forth between my normal
user account and the generic one I wanted to run startx from 5 times in
a row...

* login user1 to tty1
* startx
* kscd -> play ->stop
* three finger salute ->logout
* ^D
* login user2 to tty1
* startx
* kscd -> play ->stop
* three finger salute ->logout
* ^D

# {REPEAT 5 TIMES}

The above does NOT work with my MDK 9.1 which insists on only letting
my usual user account or root play cd's.

I figure that's another reason to usually boot fedora. But I'm concerned
that my fix might not still work when I eventually upgrade to a more
recent core.

Oh and one other odd thing... While composing this followup while
listening to my cd's (having run startx from the generic account 
& having used "su" to access pine under bash as my regular user,
I suddenly got a belated and inaccurate pop-up error just like the 
one I quoted in the original subject... Only I was already using kscd.
I was able to close it and reinitialize it and still play my cd's...

Why that pop-up was generated I don't have a clue...
