I'm not sure what caused it, perhaps installing a program ( I
believe I may have installed a new program in my last session
before the problem arose). I only have a root account and a user
account for myself on my machine. All of a sudden, when I try to
start X from my user account by typing startx, I get a command not
found error. However, X starts normally from the root account.
Using the root account I have verified that startx is in the
usr/X11R6/bin directory where it belongs and that the default path
in my etc/profile points to that directory. Moreover, the file
permissions for the directory and file appear to be correct when I
examine them with the info function of TkDesk. However, when I
try to cd to the directory from the console using my user account,
access to the directory is denied. I would appreciate any help in
diagnosing this problem.
