Does it perhaps need to be setuid? (I don't have it installed here as I
don't use it, so can't check what it is here.)
You did say that logging in at a text console (CLI) and running startx
worked, you just couldn't switch users. However, in theory at least, you
should be able to login at the console again, as a different user, and
startx on a new VT using a new display number. The first/default session
is display 0, also known as :0 (as kept in the DISPLAY variable, echo
$DISPLAY in a konsole window to see), typically found on VT7 (as the first
six are normally text consoles). Try
startx -- 1
to start a second session, on display 1 using, probably, VT8. You should
then be able to switch between them using the standard VT switching keys,
typically CTRL-ALT-Fx, where Fx is normally F7 for the first X session, F8
for the second, F1 for the first text VT, F2 for the second, etc.
I've never done that and am not quite setup to do it here (X tries to
start an invalid TWM session by default here, instead of starting the
valid kde session, I normally run a script that sets things up a bit
first, but that script isn't setup to take VTs, so I can't start a second
session), but I did just try it, and a second X session did start, it just
quit right away as the default TWM session it was trying to run was
invalid. So it should work if the default session points to KDE or
something else valid. If so, it won't give you the graphical login, but
once your logged in as two separate users, each running a separate X/KDE
session, you should be able to switch X sessions running as their
respective users with just the CTRL-ALT-Fx sequence. =:^)
