I often need to test gui applications under a different login, so I can
easily wipe out .dotfiles and run with a known environment. I've had
this working since F8 with an xauth entry that allowed the other user
access to my display. All I needed was a terminal window logged in as
the other user, and I could run apps that needed access to the X display.
A couple of days ago, this stopped working. Now, as the test user, I get
$ firefox
No protocol specified
Error: cannot open display: :0.0
and from my normal desktop login, I get
$ xauth list
xauth: error in locking authority file
/var/run/gdm/auth-cookie-XXGB42IU-for-jes
I can use "xhost +" but I'd prefer to be a little more specific, even
though I'm the only user.
Switching users through the panel "User Switcher" is not convenient: I
have to enter a password every time I switch users and I can't run
things side by side on the same display. I don't really need full
console access, just the display.
Any ideas what broke, or suggestions for getting my old configuration
working again?
