Cannot start KDE anymore

[vodoo]

This is 11.1 i586 on a server. The machine has been working with no manual intervention for 2 months and I have put it into runlevel 3 because thats enough for it. Now I wanted to start KDE to do some administrative work and to my surprise it failed to start.

I was logged in as normal user on console F6 and typed 'startx' (as usual, this worked all the time before). The error message said that it could not move /var/log/Xorg.0.log to /var/log/Xorg.0.log.old

Owners for these files are root / users. What could be wrong here? And what do you suggest to fix it?

Actually: no. No-one has started X or any graphical interface. But unfortunately I can't exclude that in the past someone (who shouldn't) has run 'startx' from the console as root.

I know that this can severely mess things up, but I have not the slightest idea where to look for any clues to verify this has happend (or not) or to fix it up.

Login as root, and try "whereis Xorg"

Make sure the Xorg binaries (/usr/X11/bin and other locations provided) are owned by root and that their permissions are right.

This should most likely fix it.

All you need is vi.

One thing, why don't you change from runlevel 3 to runlevel 5 when you need the graphical stuff?

All you need is vi.

And how do you check an archive of webcam pics with vi ?

But thank you for the hint. I will check those X11 permissions.

Oops, I found:

server:/usr/bin # ll Xorg
-rwx--x--x 1 root root 1787640  2. Jul 2009  Xorg
server:/usr/bin # ll X11/Xorg
-rwx--x--x 1 root root 1787640  2. Jul 2009  X11/Xorg

but that sould be:

server:/usr/bin # ll Xorg
-rws--x--x 1 root root 1787640  2. Jul 2009  Xorg
server:/usr/bin # ll X11/Xorg
-rws--x--x 1 root root 1787640  2. Jul 2009  X11/Xorg

as I found by comparing to another clean install of 11.1 i586. Now I really wonder how this could be set wrong. Is there any security feature wiping out suid bits?

Now this is becoming very strange, I would call it bizarre. After the corrections reported in post #7 startx worked again. I took the opportunity to update using yast and this brought an update to kernel 2.6.27.42 which required a reboot.

After the reboot KDE did not start (same error as before). I checked and found that /usr/bin/Xorg lacked again the suid bit; /usr/bin/X11/Xorg was ok. What's going on here? What is changing the permissions for /usr/bin/Xorg which requires root privileges to do?
