Unusual Login problem 17.3 cinnamon

Post by waynus » Wed Dec 23, 2015 4:36 am

I have an install of 17.2 Mint and liked it a lot. Today I attempted to "duel" boot it with win8.1 with the intention of removing windows altogether. The boot disc is the second hard drive in the machine for both os. (Don't ask)

Grub installs fine and boots into Mint. (NOt windows at first but a little magic from boot rescue and its all good)

Get to the graphical login screen of mint and it will not accept (validate) user name and password. Returning an error or just returning to the login screen.

Tried changing password using the tutorial
http://community.linuxmint.com/tutorial/view/1355 Worked well.

Tried using a number of passwords even single digit passwords

Tried multiple reinstalls and setting password to login automatically.

In the end nothing allows me to log in. Any ideas??????

Did you follow one of the tutorials on dual-booting with Windows 8.1, such as http://www.howtogeek.com/99060/how-to-d ... e-same-pc/, especially, did you install Linux Mint/GRUB in EFI mode, not BIOS mode? If not, that is probably what happened. Re-enabling Windows boot would have completely wiped the GRUB boot to Mint boot path.

Highly unlikely that the login problem is related to UEFI versus BIOS. I would even say impossible.

Simply changing the password like this should probably do the job:

If that doesn't work: what kind of keyboard are you using? And what's the layout?

Thanks to @Pjotr for the correction.

Did you check your login username? Any misspelling of that at the login will result in the same problem.

Thanks for the ideas:

Grub still boots to Mint which still won't accept the password.
cwsnyder that is how I installed Mint.

Pjotr those are the instructions I have used to successfully change the password, I have even tried using "x" as a password to make it very simple. I have reinstalled a couple of times so I am certain user name is also correct. The Keyboard is a vanilla logitech 250 wired keyboard.

The reason I asked here is I have tinkered with Linux for many years and have never heard of anything like this before. It has got to be (in my opinion) machine specific.

What's the layout that you've selected?

Have you tried another keyboard?

Different keyboard makes no difference (does work on another machine with mint 17.2). I would have thought auto login would have bypassed keyboard problems anyway.

I would have thought a hardware problem would have caused a problem with bootup or starting the graphic server, so I cannot help but think a login problem is minor.

Any other ideas?

Yup,
I've had this problem on two different systems. Tonight was the second time it happened . One machine is an Asrock990FX. The second is an Asrock880G. The symptom tonight was that I tried to add an applet but a message came up that it couldn't find a file. So I logged out and when I tried to log back in it took the password (I didn't get an bad password error) It looked like it was going to the desktop but came back to the login screen. The second system was installed 2 days ago and has been up to date.
I didn't fix the first computer but just reloaded it. Both systems are multi linux and windows (and hackintosh).

You might try editing /etc/mdm/mdm.conf, from the live session of the DVD. The relevant part is the first header, called [daemon]. For automatic logon it should be (for user account "waynus"):

Code: Select all

[daemon]
AutomaticLoginEnable=true
AutomaticLogin=waynus
TimedLoginEnable=true
TimedLogin=waynus
TimedLoginDelay=10
Replace "waynus" by your proper account name. Note that there are two instances, one for automatic and one for timed. And also note that your username doesn't contain capital letters "under the hood".

This sounds a little like the problem with the Live CD/DVD/USB on some nVidia systems.

Can you login on the terminal at all?

When booting from a Live Media version, do you get the graphical login prompt with at the top right "Linux Mint user will automatically login in 10 seconds" (Or something that resembles it?) And no matter what you do, you can't login on that either?
If so, then try booting in compatibility mode and see if that helps. If that works, you're on the track of the source of this problem.

On my desktop where I had this after installation, I switched to the terminal screen (Ctrl-Alt-F1) and installed the nVidia drivers through aptitude (in my case it was an nVidia problem) and after that rebooted and was able to get into my desktop.

At the login screen, press ctrl+alt f1 to get to a terninal. Login, then do: sudo apt-get install --reinstall cinnamon .

This is exactly what happens with the live version.

I will try the fix you have suggested. What command did you use?

Thank you to everyone for your help.

Pjotr was correct it was an Nvidia Driver problem.

I followed the instructions here: http://www.binarytides.com/install-nvid ... ntu-14-04/

Up and running now.
