I have a Cetos 5.4 system ruining x - and I also have some boot time x

Could not change boolean xserver_object_manager

Is this because Centos is different - or is there a typo in the above
command?
Richard.
I don't think that RHEL 5.4 has this boolean. Look in /selinux/booleans
and see if there is a file called xserver_object_manager.
However, if you are getting boot-time X denials then it's probably not
anything to do with the X object manager. That sounds like a kernel
policy problem. What are the denials?
Hi Eamon
You are right - that there is no such file in /selinux/booleans on my
rhel 5.4 system.
I have been getting these for ages - and have discussed with Daniel -
but not found the problem:
Here is the first - and the others are similar. I have tried the
suggested re-labelling, and moved /tmp to a tmpfs volume - but still the
errors persist:
Summary
SELinux is preventing the setxkbmap from using potentially mislabeled
files (./.X11-unix).
Detailed Description
[SELinux is in permissive mode, the operation would have been denied but
was permitted due to permissive mode.]
SELinux has denied setxkbmap access to potentially mislabeled file(s)
(./.X11-unix). This means that SELinux will not allow setxkbmap to use
these files. It is common for users to edit files in their home
directory or tmp directories and then move (mv) them to system
directories. The problem is that the files end up with the wrong file
context which confined applications are not allowed to access.
Allowing Access
If you want setxkbmap to access this files, you need to relabel them
using restorecon -v './.X11-unix'. You might want to relabel the entire
directory using restorecon -R -v './.X11-unix'.
