$ rpm -qf "$(which su)" su-0.60-alt34 (I'm using the fresh regular-wmaker with Sisyphus.) If I do "su" a single time (in an X terminal in my X session), I can connect to X (example: xmessage hi): either su - or (a user named "test") su - test -- both work. "xauth list" lists one cookie. But after doing "su" 2 times (with a different user, not to re-use the same cookie, probably), the X clients fail to connect: [imz@baseimz ~]$ su - Password: [root@baseimz ~]# xmessage hi Warning: Cannot convert string "vlines2" to type Pixmap [root@baseimz ~]# su - test [test@baseimz ~]$ xmessage hi No protocol specified Error: Can't open display: :0 [test@baseimz ~]$ echo $DISPLAY :0 [test@baseimz ~]$ xauth list xauth: file /home/test/.Xauthority does not exist [test@baseimz ~]$
