X startup problems (solved!)
A computer I was doing some upgrades on ceased working. I suddenly
found that I can no longer run X as a user other than root. If I
use xdm, I just get kicked back to the login screen. If I run
startx, the X-server just shuts down with no diagnostic messages.
Unfortunatly I can't even catch the error messages
when using xdm cos they get sent to tty1 and immediatly
disappear behind the login prompt :( When using startx
there is nothing abnormal reported.
I did manage to see this in ~/.xsession-errors :
exclusive open for tmp_name failed in m4_defs: Permission denied
The /usr is shared between 2 computers and works fine
on one of them. Nevertheless I tried doing a
chmod +s /usr/X11R6/bin/XF86_SVGA and even a
chmod +s /usr/X11R6/bin/xconsole to no avail.
(both currently has permissions set to -rwxr-xr-x)
Someone suggested that one could try:
rm /dev/console; mknod /dev/console c 4 0
but this made no difference.
The machine usually has /usr and /home nfs mounted.
I tried using the local copies (straight debian)
but this made no difference. That leads me to believe
the problem is in another directory.
I have rebooted several times, so it shouldn't be a
/tmp/.X11 problem either. (it currently has permissions
set to drwxrwxrwx)
Any other ideas ? (it must be something to do with
permissions cos root login gives no problems !#%?!#@X)
addendum: Just before I was about to post this message
I came across the following in DejaNews:
[the messages in the .xsession-errors]

Yes thats the solution. The permissions were set wrong for /tmp
People have reported that this is caused by the base-1.1.0-13.deb
but I have base-1.1.0-14.deb on 2 computers and only 1 of them
caused these problems. Could it be due to an unclean shutdown?
