installed "sux" but still cannot start x app remotely

[Pollywoggy]

I installed sux and then tried again to start a KDE app after connecting to the other user's account using the sux command:

sux - user5

When I try to start the KDE app I get this:

kate: cannot connect to X server :0.0

Both users are on the localhost and I will have to set up SSH on the other user if I can't get sux to work.

Any ideas why sux is not facilitating this app to run in another user's session?

You need to explicitly allow access to the X server. This works for me:


xhost +
su - user
kate

For more information:
man xhost
