You might try this to see if it might “fix” the problem. Open up a terminal session such as konsole. Then type the following command and see what this does:
dbus-lanuch kwrite
Then try it again with kate:
dbus-lanuch kste
Here is some information about the dbus-lanuch command:
While there may be somethiing wrong, but I also see a problem in what you are doing.
II assume that you do have a GUI session running as user wei and that you run a terminal session (konsole or xterm or likewise) inside that GUI session.
Now as you start a graphical application there it will open a (or more) window(s) on your desktop. But as you try to do that as another user (in this case root, but that is an unimportant detail) this window will not open when the owner of the session (wei) will not allow this. Imagine, all sorts of users on your system (or even from outside) that started opening all sorts of windows on your screen while you are working!
You can give that allowance this with the xhost command. Thus test if
wei@linux-wzpd:~> xhost +
access control disabled, clients can connect from any host
wei@linux-wzpd:~> su -
password:
linux-wzpd:~ # kate
but more normally if you have a file that you want either to create or to edit, called “somefile.txt” located in directory “somewhere” at the address /path_to/somewhere/somefile.txt, you would type this fuller expression:
