Ubuntu :: 'gdm' User Does Not Exist
Oct 3, 2010
I installed Ubuntu 9 on my kids' computer a while back and usually the computer boots up and goes directly into Ubuntu. However, this morning when they booted it up, the following error message displayed: "The GDM user 'gdm' does not exist. Please correct GDM configuration and restart GDM." It seems that they had inadvertently messed up some configuration files. After pressing 'OK' it asked me for my user name and password, which I supplied, but that didn't work either. So, either I've forgotten my password or my kids seriously messed up their computer, so much so that I can even work with it in command line. I was thinking about simply reinstalling Ubuntu and possibly updating to version 10, but I'd rather not lose the files on the computer. Thus my question: Does anyone see a way of not losing my and my kids' files while getting back into Ubuntu?

User root does exist. Sendmail doesn't deliver email to local user. This is standard instalation from apt-get install. Everything worked ok since year. Everything worked ok until recently. The server worked just over a year.

I have two machines running SQUEEZE, both installed and configured within the same week (not simultaneously). Both get the users info from a NIS server. In one of the machines (named "corona"), users cannot login, neither locally nor by ssh, in the other one ("xxlager") there is no problem. Both mount the users home directories by NFS. I have not found much useful info in the web. /etc/passwd, /etc/group/, /etc/shadow, are equally configured. The only difference I have found is when I use getent. Using "getent passwd isaenz" on xxlager yields:
isaenz:x:1001:1001:User Name,,,:/home/isaenz:/bin/tcsh
but on corona the result is
isaenz:x:1001:1001:User Name,,,:/home/isaenz:
so the shell info is empty.
Checking /var/log/auth.log I see a message saying:
"User isaenz not allowed because shell does not exist"
But "ypmatch isaenz passwd" returns complete information for isaenz, both on xxlager and corona.

I just purchased a new server and loaded it with Ubunut server 10. I installed apache2, php5, and mysql5. apache needs a little bit of configuration left (I need to tell it to accept index.php in addition to index.html), but other than that, all the php is working. MySQL is working as well, at least on the server. If I do a "show databases;", it shows all the databases properly. I loaded phpmyadmin on the server for testing, but I'll be removing it once everything works - this is my production server. phpMyAdmin can find all the tables, perform successful queries, and do everything I want it to, HOWEVER If I try to use the login page, I get the error mentioned in the title of this thread.
The database is a carbon copy from my development server, which works flawlessly. All the php and html pages are exactly as they are on the development server too, yet I still get that error. I've reloaded all pertinent programs (apparmor, apache2, and mysql). Apparmor was because I had to declare some new lines for mysql to access a different location for the DBs I resolved the "can't load InnoDB issue", but this one is stumping me.

I have a server with a static IP that I use as a sendmail server. The problem is that port 25 is exposed. As a result, anybody can login to the SMTP server and send mail from my domain as a user that does not exist as well as email from other non-existant domains. I'm sure there are sendmail options that I can enable to do some checks, like if the user exists on that server or if the domain is the same on the server, etc. I was wondering if you guys can mention a few that I can add to my sendmail.mc file?
I have thought about auth login, the problem is if auth login is on my public port then I won't be able to receive email from gmail because it would be unauthenticated. Also, I only have 1 mail server. I know the ideal solution is to have 2 mail servers. One for outgoing mail/internal mail server where you can enable auth login and the other for incoming mail which just acts as the relay to the internal mail server. That way spammers can't login to send mail out. That's another question I had, how do I configure sendmail to only send email out/in?
Anyhow, so I have to make do with 1 mail server for now. So I decided to add a few rules on iptables. I grabbed the IP range that gmail uses when I receive mail from then and added it to my iptables with the following command.

I no longer have access to my root desktop. On a session I attempted to change the root username but i apparently assigned it a wrong directory that does not exist. When I rebooted with my new root username, i was instead recognised as a simple user (no root privileges). I tried the console to change to "old" root but root password is not accepted and there is no way to access to sudoer files. it seems that inserting a new username requires root privileges and i am back to square one. Simply logging with old root username and password after restart gives me a blank screen with nothing on it and cannot even reboot.

But I've gotten as far as getting davfs to work on RH Linux. However, on SuSE I'm logged in as root, but when I issue the mount command I'm getting "user davfs2 does not exist". (I was getting "group davfs2 does not exist", so I created the group (groupadd davfs2) then added the user davfs2 to the new group by following the instructions at The Nerdrium : Linux : Creating Groups.
The command I'm issuing is: mount -t davfs http://.....
I get challenged for credentials, but after I enter them I get the "user davfs2 does not exist" message.

I am dual-bootng Ubuntu 9.10 and Mint 8, both of which use GRUB2. The Mint 8 GRUB sets the initial menu since Mint was loaded after Ubuuntu 9.10. Since both use GRUB2 I was not concerned about this.
Both before the installation of Mint and afterward I see a series of messages fly by on the screen when Ubuntu is booted. These come right after the initial presentation of the Ubuntu logo.
By restarting several times I can read the first several lines. They are:
Mount: Mount Point 0 does not exist
Mount 0 terminated with status 32
Mountall: Filesystem could not be mounted
Further lines follow but I would have to reboot umpteen times to have any chance of copying those.
I have looked in the various Ubuntu GRUB2 files for "Mount Point 0". I do not see any reference to it.
GParted, BKID and etc/fstab all agree on the UUIDs set for my Ubuntu/, Ubuntu Home and Ubuntu swap file.
I see nothing like this when I boot Mint 8.
My questions:
What is the point to error messages (I assume that is what they are) that fly by too quickly to be read? Are they saved to a logfile somewhere?
What is "Mount Point 0"?
What does it mean in this context to say "Filesystem could not be mounted"?
This is all very curious because Ubuntu proceeds to mount and run just fine.
What is Ubuntu trying to do as it starts up that it cannot do?
How do I repair whatever has to be repaired in order to turn off these messages?
I have looked through such GRUB2 dcumentation as I can find without seeing any reference to this.

I would love to change the boot order on my laptop. Mainly because it is shared, and I am the only one who uses Ubuntu (version 9.10)... So everyone keeps moaning for me to change it!
Following all the sound advice from this forum it looks easy... Except /boot/grub/menu.lst does not exist!

I would get the message that the uuid file does not exist. I've been online looking for fixes since yesterday morning and nothing has helped at all. I've read online that I should run fdisk -l to obtain info to share with others, but that command doesn't work in any command prompt I open. I am running Ubuntu 9.10 with the latest patches and I'm sure you guys know that it runs Grub2 loader...if that helps at all.

I just installed 10.04 over my previous dual boot with Windows7 and 9.10. Went well. Now, in the Grub2 menu, there are like 14 kernels. I tried to find them in Synaptic to delete them, but they are not there! So, I went to grub.cfg and deleted the entries, updated grub, and they were back! How do I get rid of these entries?

I have a server running ubuntu 8.04 with apache2. What I'd like to know is how to go about setting up a domain name? I've looked at a heap of hosting sites, but they son't seem to allow you to specify your own IP address that you already have. Also, I'm not sure about what, if any kind of DNS software I would then have to run on my server. At this stage I'm only doing preliminary research about it I guess.

I recently have been trying out the Ubuntu live CD.
I have a shared computer where some are suspicious of anything other than Windows.
The live CD is an excellent way forward.
As I understand it Ubuntu is loaded into the computer RAM, thereby it makes no actual changes to the computer as it does not load into the hard drive.
I have noticed that if I have been doing work on the computer and forgotten to empty the trash, when I run the live CD on another occasion this material is still in the trash.
Is data put into the trash saved to the hard drive?
It does not matter to me if it is as long as I have deleted it but I would like to know where it goes if it does save to the hard drive.
I am running Windows 7 on a 64bit PC
