[Wine]WinNY and Wine

Thu Jul 14 12:22:11 CDT 2005

Isaac,

You can login as root, and then switch to a another user (with su) before
running wine (workaround over your KDE issue).

Running programs with non-root users is a SECURITY precaution (a _big_
_really_big_ one) -- but it should NOT affect program functionality (in
general); Few programs might require root privileges to start though - such
as accessing ports less than 1024...

About your WINE problem: did you try using a newer version of WINE?
Sometimes it helps and sometimes (MORE) it does NOT :)

Best wishes,

Shadi

Tom,

I truly appreciate your comprehensive explanation, only a fraction of
which I was already aware.  I have been convinced to not use superuser
to login.  However, when I started up kde as a user (after adding the
'echo "exec startkde" > ~/.xinitrc' command), it just hanged on the
splash screen as it was trying to load peripherals.  I believe this is
because I'm unable to access everything that I installed as root, and
I'm not sure how I would gain access to this.

I realize this isn't directly a wine-related problem, but it will be
necessary for me to overcome this before I can attempt to run wine
without logging in as root.

Thanks,
Isaac (I'll stick with my real name ;) )
