My log syntax: -> what I input; == the resulting output; => observation
=> This log now in VT3

=> in VT4
-> xinit -- :1 & ==
drip under pressure.

program as a non-root user or by removing the suid bit on the executable.

Thanks.

PS. An excelent article by David Davidovic @ http://tutplus.com
points to <gamma correction> problems. But how it could start OK,
and later change to BAD is a mystery for me.

BTW there's 2 problems here:
1. xpdf ..etc BECOMES badly displayed after OK when initially run-X.
2. It would be interesting to keep the initial X, and experiment with
  others, at the same time.
