Can somebody please help me?
 

Im recently running on Linux Mint Mate 18 sarah and it was running great running fast and smooth then one day i tryied to login and it looped me back to the login screen can somebody please help me

Hi Crash202021,

did you install any new software? You should try switch to the console (STRG-ALT-F1 oder -F2) and try to log in there. If that's working there could be some problem with the graphical login manager. You could also check the error logs in /var/log/Xorg.0.log.

Hello and welcome to the forum :)

First, please read here. The more details we have, the better we can help you. ;)

In addition to what xcom has suggested, do the instructions here help?

Regards...

Yes i can
 

Yes xcom i can get in to the terminal from the login screen

I tried to switch from mdm to litedm didnt work ethier

Sounds like problems with the login manager or the desktop. Could you post the contents of
/var/log/Xorg.0.log
(I don't know wether Mint is using journald exclusively but if there is no Xorg.0.log you try "journalctl -e _COMM=Xorg" at the console without brackets)

Lines starting with (EE) are the interesting ones

Edit:
By the way, I had a similar Problem on Fedora 22. After installing the proprietary NVIDIA driver and using the gdm, I was dropped back to the gdm every login attempt. Did you install a binary driver for your graphics card?

Hi. Your title is rubbish, many may ignore... can change it to reflect though? ;)

Have you tried:if that don't work could switch to KDM and see? :hattip:

Running completely bypasses your Mint Update Preferences and will install all Five Levels of Updates regardless of your Setting (defaults are Level [123]) shown in attachment.
Level 4 - Unsafe Updates
Level 5 - Dangerous Updates

Just sayin'

Did you check if your capslock key is engaged thus making you type a wrong password? (or numslock key depending on the keyboard). (Shift+Fn would engage the numpad mode on an older laptop I had, super annoying, especially if you have cats, keyboard shortcut ninjas they are).

Did you try creating / logging in as a different user?

I don't know if it's relevant but an update of xserver-xorg-video-intel (2:2.99.917+git20160325-1ubuntu1.1) came down to my Linux Mint 18 MATE box earlier today. I too had a wee issue, perhaps related to the update, where the machine rebooted half-way through the boot process, but I'm hoping it was just a teething problem as the subsequent reboot worked fine.

Prove su won't or whether or not to run systemD or a firewall or... :rolleyes: just saying...

In a terminal : you can use su (or gksu) to change your identity to root. However, it's recommended to configure and use sudo (or gksudo) to run a given command.

Using sudo is better (safer) than opening a session as root for a number of reasons, including:

Sudo Manual Pages – Sudo (su "do") allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments. For more information, see the introduction to Sudo. Sudo is free software, distributed under an ISC-style license.

jamison20000e:
It's not about sudo or su or sudo vs. su

There's a reason I ignore your posts.
You're a trainwreck.

Not on topic: Habitual, prove that too. One "security expert" disses sudo and you ignore all other advice? No wonder you have such an addiction problem, you obviously can't learn! :doh:

Now children: Behave. This is not helping.

Very likely a minor software upgrade or install has broken something minor. I have had this happen before.
Be calm, you have the right people here to advise you. Since I do not use that version, I will defer to those that do and off no other advice at this time.

Perhaps illustrations will seem less severe.

A normal Mint Update widget screen with Levels 123 select selected shows "Your System is up to date"

sudo apt-get upgrade output that illustrates my point is attached. And looks far from "Up to date" all of a sudden.

I'm not picking on jamison20000e exclusively,
is used liberally here by well meaning people, Some of them like me use Mint.

I just think people giving the advice should consider what is actually being done to the system when that advice is offered.

End Transmission.
