Want to make /tmp non executable but X crashes

Using noexec in fstab, I Want to make /tmp non executable but X crashes when I do. I see in /tmp/.X11-unix/XO is a socket file. Does this file need to be executable? Is this why X crashes when I set /tmp to noexec? If so, anyway around this so I can mark /tmp noexec and still run X?

Hi,

The info provided by you is somewhat limited.

I can only assume that /tmp has its own partition and you do not mention the complete /tmp related line you have in your fstab file.

Maybe this article will help you iron out the problems: Secure temporary files in Linux

Hope this helps.
