I was half way through an update and needed to stop the download and switched my computer off (Dell latitude E6500) (Ubuntu 14.04.4 LTS). Now the screen keeps looping back to login after I enter my password. Help please!!  😞

My Ubuntu is stuck in a login loop when trying to enter my desktop. When I login, the screen gets black and soon after that the login screen comes back.   I've read that the problem might be caused by an error depending on the graphics, here's my graphics card: ATI Radeon 7670M

I used the built-in upgrader to upgrade to 19.04 today, and I'm now stuck in a login loop. I have tried many solutions from forums, but nothing has worked. Is there something I'm missing or anything else I should try?   From what I've seen, I don't think that there is an Xauthority file on my computer. I'm on a Dell XPS 15 with a GTX 1050Ti Max-Q GPU, and a Core i7 processor. I also have a Windows dual boot, and while Ubuntu's my main OS, luckily almost everything is on GitHub, Google Drive or my Windows partition.

I disabled all services and startup applications and now the computer won't let me log in. It will get me to the initial startup screen, but it won't connect to the Internet. Then when I click or press a key to log in, the password box never appears.   How to go back to normal boot? Shift+Restart or F8 to get into safe mode doesn't work. Restoring to a system restore point resulted in an error. Even Resetting Windows didn't work.

This happened when I attempted to upgrade from 17.10 to 18.04.  I receive this error during boot, and my Ubuntu that I've had a few months running without issue twice (not counting during the upgrade) randomly reset to select user and login screen but let me back into my desktop no problem.   During the unpacking part of the update it did this and hung in a select user, type password loop not letting me into the desktop. I turned my computer off twice and on the third try I get a consistent error 256 after selecting Ubuntu from the GRUB menu. My system was at full battery during all these random resets.   How do I fix my system without losing my files? It was only 1/10 or 1/20th unpacked on the update bar. I'm on an Asus with Intel processor/graphics card.

I updated notepad++ and it started writing to the screen.  I quickly closed it not knowing what it was, but now I'm curious do I have a 'hacked' copy of notepad++?

I have upgraded Ubuntu to 12.04 and now I have a problem in logging in after locking the screen: it says the password is incorrect even though I provide the valid password. I found a temporary solution by switching users and logging in again with the same user.

Something came up today that bugged me a bit, I left my laptop on battery power before going to bed. When starting it up the battery was dead. I plugged it in, and here is what happened:  The startup progress bar came up for a while and then a forgot password prompt came up, with questions like: "set a new password" + 2 other options that I can't remember (they weren't relevant) and a previous and next arrows.  Puzzled, I hit previous and the dialog froze. I proceeded to restart again and ended up on the same dialog, I reset my password to the same as my previous and that was it.  Any idea what might have happened?

I recently purchased an MSI ge40 laptop.  It's been running fine (very hot laptop though) except for one issue. When I use windows key + L to lock the laptop, upon typing in my password and logging in, pressing any key that would normally be used in combination with the windows key activates that program.  So, if I hit win+L, type password, then hit 's' the search comes up. Etc.   This also randomly seems to happen when I am not using win+L. I might just be browsing the web and then I hit 's' when I am typing a url and then boom, search pops up. Very annoying.  I fix this by hitting the win key....sometimes onces, sometimes 10 times. Doesn't seem to have to do with the hardness of the strike.   I guess I'm at a loss. I researched this and only results about vista and 7 come up.

How can I disable password request after suspend in Ubuntu 18.04? I have already turned off the screen lock but that didn't fix it.  I am new Ubuntu user. There seems to be lots of information on how to fix this in older versions.

I have ubuntu mate. I have recently changed my password using the passwd command. I know now that I have made a mistake because I also have my home directory encrypted with the previous password.  Consequently after enter my new password at login screen it return me back to the login screen.  Can someone please help me?  I am able to enter to grub boot menu and shell, i am also able to log into guest user. Sorry if the topic is duplicate but I haven't found the same question  Thanks in advance.

My Ubuntu 16.04 hangs on shutdown/restart requiring me to press and hold the power key to turn the machine off... I don't know how to report this as a bug and what commands to run to show the necessary hardware/sys log info? Any help would be hugely appreciated!

I performed the most recent kernel update on my Dell 5290 2-in-1 earlier today.  But moments after I plug it into its docking station, the screen flickers, blanks and freezes.  The only item left on the screen is the mouse pointer, and it is stuck.   If I leave the tablet not plugged in, it runs just fine.  It seems to be the docking station that triggers the freeze.  That said, I can log into the tablet via ssh even with the screen frozen.  So the system is still running.  But if I try to reboot the tablet via the reboot command, nothing appears to happen. sudo reboot -f will reboot the system, while sudo reboot will not.  Any ideas where I should start looking to identify this problem?

I'm confident that I do not need a password for my computer. How do I remove passwords for things like when the screensaver activates and installing software?

I have verbose mode turned on always so I can see if a kernel panic or some error happens. After having it on for a few times, I started to notice that most of the boot was happening after the login. I can't show a picture as it is in boot, but the login screen loads before most of the OS. This is only after a cold boot but I can't seem to find any information on this. All I want is some information on this. EDIT: Basically, the machine starts to boot, the apple logo pops up, a small box of text scrolls down, where the rest of the monitor is not used, it shows the login screen, and after I type the password, the login screen goes away. now the whole screen is used and the rest of the machine boots up. EDIT 2: There is no firmware password. I have not locked the firmware.

Today I installed Ubuntu 14.04 on my computer. I have dual monitor setup, and they work perfectly when I'm logged into the operating system. But every time I have to login in the login screen, the screens get reversed. And what I mean is that instead of moving the cursor on the main screen to the left to move on the secondary screen, I have to move it to the left side. After login it changes to normal.   Any suggestion would be helpful.  Graphics: NVidia GTX275. Latest drivers installed.
