If you paste this paragraph of commands to a terminal,
cat >testboot <<\E
#! /bin/bash
(date; ls -ld / /tmp /tmp/.{ICE,X11}-unix) >>ralph.txt
ls -ld / /tmp /tmp/.X11-unix
E
chmod a+x testboot
it will create `testboot' in the current directory and you can run it
with `./testboot'. You've created a shell script; a text file of
commands for the shell that's had its mode changed (chmod) to be
executable.
Cheers,
Ralph.

Simply put, you're getting an error from xorg saying the permissions on
/tmp/.X11-unix aren't as it wants, but its earlier code, attempting to
set the permissions to that value are flawed.

You must have run something slightly different because there are two
minuses in the errors. Don't attempt to re-type it into a terminal
window because, unless you understand the meaning of every bit and
twiddle, it's hard not to make a typo if you treat it as plain text. I
suggest you copy and paste it from the email to the terminal.
Then, to give us the output, copy and paste from the terminal back to
the reply. Include the shell prompt before, where you entered the
command, and the blank one after. That way we can see that what you
actually entered, and tell that the output finished by the re-appearance
of the shell's prompt. So, for the first command above, it would be
something like
$ ls -ld / /tmp /tmp/.X11-unix
drwxr-xr-x 22 root root 4096 2010-07-24 07:23 /

drwxrwxrwt 2 root root 4096 2010-08-14 09:08 /tmp/.X11-unix
$
(`$' is my shell prompt, yours will be different and longer.)
The second command above, the
(date; ls -ld / /tmp /tmp/.{ICE,X11}-unix) >>ralph.txt
one that builds up a log of results in ralph.txt in your home directory,
stores its output in that file so you won't see anything, the shell
prompt will just re-appear. A cut-down version that will display it on
the screen is
(date; ls -ld / /tmp /tmp/.{ICE,X11}-unix)
I've just removed the re-direction that appends the standard output of
the commands onto the end of ./ralph.txt.
Cheers,
Ralph.

just run the above output failed with:

ls: cannot access /tmp/.X11--unix: No such file or directory
Even trying with sudo in front it failed, should the () or {} be included?
Will bring the laptop to Blandford meeting so you can see what's happening.

If you wish, after a successful boot you can edit the file and add an

the .{0,1,..}.logs are written by the server, I do have those when I
start one or more servers manually.
automatic use of gdm/xdm would require a change of runlevel, I'll have
a nose around the default setups provided sometime in the next frew
days and see what's up. will get back to you on this.

I don't know. I think one gdm handles the possibly many X servers and
arranges :{0,1,...}.log files. It maybe something related to booting

Hi Clive,

You need to keep an eye on that directory and spot the pattern between
the :0.log* files there and your attempts at logging in.
Off-list, you wrote:
> Attached is a screenshot of the 0.log files in var/log/dgm.
I've uploaded it to tinypic.com.
http://i36.tinypic.com/2cookkj.jpg
but another time, the output of
sudo ls -l /var/log/gdm
gives us as much info, if not more, in an easier format to pass around.
:-)
> Looked into the small 0.log.2
I see :0-slave.log.2 is also smaller than the others and from the same
time. Then :1.log is from a few seconds later. It looks like a :1.log*
may be created everytime :0 fails?

Probably. I found on Google Codesearch that xserver-wrapper.c has
#define X_SOCKET_DIR "/tmp/.X11-unix"
#define X_SOCKET_DIR_MODE (S_ISVTX | S_IRWXU | S_IRWXG | S_IRWXO)
...
if (statbuf.st_mode != (S_IFDIR | X_SOCKET_DIR_MODE)) {
(void) fprintf(stderr, "X: %s has suspicious mode (not %o) or is not a "
"directory, aborting.\n", X_SOCKET_DIR, X_SOCKET_DIR_MODE);
exit(1);
}
(If X not being Y is an error, why not put the unexpected value in the
error message!)
So it's complaining that /tmp/.X11-unix exists but it isn't a directory
that has `drwxrwxrwt' as its permissions. That directory is created by
/etc/rcS.d/S70x11-common so for some reason that either isn't working,
or it's work is being trampled afterwards.
Is there plenty of space when you do
df -h /tmp
and what does
ls -ld / /tmp /tmp/.X11-unix
show now, when it's all working?
Cheers,
Ralph.

Re: [Dorset] Boot up fault Ubuntu 10.04
Ralph Yes. Locks up after showing the fault warning, no button pressing is acted on even "Cntr/Alt/del". Screen is black, like a terminal window, fault shown at top line. I gave incorrect info as Cntrl/Alt/Del does a restart. Sorry. Nothing works except by pressing the power button. (configured to shut down). Appears to close correctly, no indication of anything untoward happening. #dorset think userspace is involved in handling that, suggesting it may only be starting X and/or gdm that's the problem and the rest of the machine is running fine. Have a look in /var/log/gdm. An `ls -ltr' command will list the most recently modified ones at the end. The last one will probably be :0.log, meaning the log file for the X server's :0 display. Perhaps there's something of interest. Yes. but what am I looking for? so you'd be able to look in it as a normal user. I see on 10.04 it's now $ ls -ld /var/log/gdm drwxrwx--T 2 root gdm 4096 2010-08-14 09:08 /var/log/gdm Doing above resulted in same output but date stamp different (as I expected).

Regardless of the permissions on the file, each directory in the path to the file needs execute (AKA search) permission if the kernel is to let you access an entry in that directory by name. Read permission on a directory lets you see what's in it. (It used to be a directory was opened and read just like a file to see what inode numbers it referenced and under what names.) But if there's no read permission I can still access a file in the directory by name if I already know its name, e.g. .bash_history. drwxrwx--T 2 root gdm 4096 2010-08-14 09:08 /var/log/gdm So for `other', none of rwx are set. The `T' indicates the sticky bit is set but, being a capital, `x' isn't. (It restricts who can delete files in that directory.)

I'm not sure if Ctrl-Alt-Delete should do anything if you're on a virtual terminal. What about Alt-1, Alt-2, etc? They switch between the different VTs, e.g. you may be left on VT3, Alt-1 will switch to VT1 and Alt-3 will return you to seeing that error message. > > > If I shut down > > > > How do you commence that?

Ah, sorry. On 8.04 it's $ ls -ld /var/log/gdm drwxr-xr-x 2 root root 4096 2010-08-19 22:06 /var/log/gdm so you'd be able to look in it as a normal user.

Anyone else? `sudo gnome-open /var/log/gdm'?

[Dorset] Boot up fault Ubuntu 10.04
Last week my /root partition filled up and the laptop would not 'boot'. I looked at the system by booting from a live CD and Gparted to confirm a full partition; I could not extend / as the swap and /home partitions followed directly. After backing up /home to another area I played around with the partitions, shortening, making space, moving each partition and ended up with twice the space for /, 1.4GB swap and a shorter /home: left some space (unallocated) in case the problem repeats it's self. Shut down and re-started with fingers crossed, booted OK and all files still there, system working normally. Following day after several 'boots' it suddenly started intermittent failing during the start with: (process:349): GLib-WARNING **: getpwuid_r(): failed due to unknown user id(0) If I shut down and try again it will complete the boot and login screen, working as normal. Sometimes it may need 2 or 3 tries, other times it behaves normally. Watching the boot screen process (visually) it starts with Unbuntu screen (underscore dots flashing) gets past the webcam checking (webcam flashes) then fails before Login screen. When moving the partitions I did not re-do the partition table: should I? Sorry for long text but that's the order of doing things. I hate intermittent faults!!
