avahi deamon failed at startup

I am getting avahi daemon failed message at startup and after that the screen keep flickering but no login screen appears. I have read somewhere at the Internet that the cause is full usage of /tmp. Further they advised to delete /tmp/X0-lock. I am using fedora9. Please tell me:
1. If deleting /tmp/X0-lock will be safe?
2. To do this, how can I access the command line when system is not starting up ?

Thanks

How to access root to view /var/log/messages

Someone has suggested that this may be caused when there is no space left in the Filesystem partition. I must view /var/log/messages to see what happened when the problem occured. But at the time I am logged into the system using LiveUSB :

Code:

[fedora@localhost ~]$ su

[root@localhost fedora]# cat /var/log/messages | grep -i avahi

Jun 23 17:18:26 localhost avahi-daemon[3049]: Found user 'avahi' (UID 498) and group 'avahi' (GID 495).

Jun 23 17:18:33 localhost avahi-daemon[3049]: Registering new address record for 192.168.1.2 on eth0.IPv4.

But I think these /var/log/messages doesn't belong to the one that created the problem instead they belong to that of LiveUSB only. Please note that when I put su command, I am not promted for password. So I don't think I am actually logged in as root.

This is very disastrous situation. Please help me on how to access root or any other user to view /var/log/messages or to delete some files from Filesystem.

Thanks

Unable to empty Trash now

When booting through LiveUSB, when log-in screen appears, I clicked Cancel instead of OK. Then Fedora Live, Automatic Login and Other are shown as login options. I selected Other and in the username box that appeared next I typed root and pressed enter. I was never asked for the root password but I can now access all my drive partitions.
I noticed that zero free space was left on my Filesystem. So I have now deleted some bulky files to make some space. But the problem is that deleted files are accumulated in the Trash and it is not being empted. I know that Trash folder is found in /root/.local/share/Trash/files directory. But I found no files in this directory. When in Trash folder I select Empty Trash, nothing happens. When I manually delete a file (say patch-ns-2.27-FSR-v081.zip), I get this message:

Code:

There was an error getting information about "media____.Trash-0_patch-ns-2.27-FSR-v081.zip".

Show more details:

Error stating file '/media__.Trash-0/files/patch-ns-2.27-FSR-v081.zip': No such file or directory

I have already searched a lot on this issue on the Internet but no trick works. Please help me.

I don't know which information will be useful to show here. Please consider this:

Code:

[root@localhost ~]# df -h

Successfully Rescued !!

What I did is: I stopped deleting any more files from the filesystem as all the files I was deleting were merely being accumulated in Trash directory, releasing no disk space.I moved some files from filesystem to other partitions and then deleted such files from the other partition. Now these files were deleted bypassing the Trash.

Thanks

PS: I think this will be the first thread of it's kind in which the problem is reported and resolved by the Original Poster himself only.

Very simple solution

All you have to do is to insert the USB that comes with the machine, and then turn on the machine and let it start, it will take you to a panel, select backup & restore, press yes to confirm the restore. After finishing the restore and restart the machine everything will be back to normal and the machine will work just fine :)
