Hi,
I have complete installs of recent versions of cygwin and cygwin/x (setup
version 2.457.2.2, 6.8.2.0-1 of the xorg-x11 packages) on Windows XP SP2
and have a problem with starting the X server. If I log in as a user with
admin privileges, or the user who installed the software, I can start a
bash shell and run startx without problem. However, if I log in as another
(Windows domain) user, often I cannot even start the bash shell (permission
denied by Windows). By changing security settings on c:\cygwin, I can
generally start the bash shell, but I cannot start X, getting the error
dialog containing:
A fatal error has occurred and Cygwin/X will now exit.
Please open /tmp/XWin.log for more information.
Vendor: the Cygwin/X Project
Release: 6.8.1.0-5
Contact:
XWin was started with the following command-line
X :0 -multiwindow -clipboard
The contents of /tmp/XWin.log contain a message saying that /tmp/XWin.log
could not be written to. Changing permissions of this file (as an
Administrator) to 666 avoids this, but subsequent attempts still produce
the fatal error with a message to the effect that a socket could not be
created.
Is there a definitive document describing the necessary permissions on a
Windows box to permit use of Cygwin and Cygwin/X by users authenticated to
a Windows domain? If not, can someone offer advice on how to get this
running so my office can make use of cygwin/x as something other than a toy?
Thanks,
