The MDM user 'mdm' does not exist. Please correct MDM config

Postby jaishakarh » Sun Jun 10, 2012 3:36 pm

I cannot boot into linux mint 13 maya mate 64bit.

I downloaded the 64 bit version of mint maya and loaded it on a 8GB pendrive through ubuntu using startup disk creator. And then when i try to boot into the live desktop environment this is the error that is produced.

This is the error that is produced:

The MDM user 'mdm' does not exist. Please correct MDM configuration and restart MDM.


System config:
Processor - AMD Athlon(tm) II X2 260 processor 3.2GHz
GPU - Nvidia GTS 450
RAM - 4GB

Please anyone HELP ME!!
THANK YOU!!

I ran into this same error after installing MDM.

This is what worked for me:

Code: Select all

sudo groupadd -r mdm


Code: Select all

sudo adduser mdm

you'll need to give a password for the user "mdm"

Code: Select all

sudo gpasswd -a mdm mdm

You can create users and groups while running the live cd. They just won't persist through a reboot.

Write down on a piece of paper the commands in the code blocks above. After clicking "OK" on the error dialog, you should be in the console with sudo priviledges. Start typing the commands, one at at time, in the console.

If

Code: Select all

aduser
doesn't work, try

Code: Select all

useradd

Try

Code: Select all

ctrl alt F2

then enter the commands at the prompt.

The console I am referring to, isn't a little window, it is the prompt on a blank screen. If there is no prompt, then you're only other option is try LinuxMint Cinnamon. It uses GDM instead of MDM.

I had this exact same issue. I had used the Universal USB Installer to put Mint onto a 16 gig usb drive. The problem turned out to be that I didn't allocate any persistent storage on the USB drive. I redid the drive adding 500 mb persistent storage and everything worked like a charm.
