I have just installed the 9.1 Pro upgrade this morning. Most things seem to be working right, but my old buddy "sux" no longer gives the root user access to the display. After doing "sux -", I do become the root user, but running any X application gives me errors like: michaeln@seahunt:~> sux - Password: seahunt:~ # id uid=0(root) gid=0(root) groups=0(root) seahunt:~ # xclock Xlib: connection to ":0.0" refused by server Xlib: Protocol not supported by server Error: Can't open display: :0 seahunt:~ # I have been using sux for so long now I forgot how to solve this. It's always just worked in the past. There doesn't seem to be a man page for sux, and sux --help just gives a usage message that isn't particularly helpful. Has anyone else seen this? Thanks Michael
