X: server must be suid root

[valentina dyachenko <vdyachenko@atyrau.oilfield.slb.com>]

Hi, I found your message in internet :
Hello,

This is the second time I've posted this question. If someone could
suggest a better place to post it, please do. I'm not sure if it would be
appropriate to post to the debian-x mailing list.

I know I've seen this before, but I cannot find the solution anywhere. I
can run X as root just fine. But when I try to run it as a user, I get
the following errors in /var/log/XFree86.0.log:


(WW) xf86ReadBIOS: Failed to open /dev/mem (Operation not
permitted)


Fatal server error:
xf86OpenConsole: Server must be suid root

Here is some info:
XFree86 Version 4.2.1.1


hardin:/usr/X11R6/bin# ls -l X*
-rwsr-sr-x    1 root    
root         7476 Aug 29 11:30

-rwsr-sr-x    1 root

-rwxr-xr-x    1 root

hardin:/dev# ls -l mem
crw-r-----    1 root    
kmem       1,   1 Aug 29 21:51
mem


hardin:/usr/X11R6/bin# cat /etc/X11/Xwrapper.config
allowed_users=console
nice_value=-10


And I have exactly the same problem. If you found solution
could you please share with me?

Thanks,Valentina
