I changed some settings in Unity and then I ran the Setsid unity command and now every time I try and boot up Ubuntu I can login just fine but the desktop is completely empty besides my background picture. I'm not sure how to fix it as I can't open the terminal or anything. Please help?   Thanks!

I've installed Ubuntu 18.04, and everything worked excellent until I decided to try Unity desktop. Bottom line - I've uninstalled unity desktop completely. But! I have some stuff that didn't recover to previous state. First is the login screen that have changed, and I want to bring back the gnome native login screen.  Second is the Lock screen (that is shown on wake up). Before unity it was the gnome's one, that you can change it's background in the background properties.  After unity it changed to annoying login form that doesn't work if the keyboard layout is not english, and you just can't switch between layouts in this form and all the window around it. So if before sleep I was using hebrew or russian layout, on wake up I just cant log back in, and I have to restart the pc.  How can I switch back to normal gnome stuff? Thanks!

System settings is missing. I tried reinstall it as it mentioned , but it seems to be installed and deactivated. This problem occurred when I installed Elementary desktop environment and uninstalled it afterwards.

I installed Ubuntu 18.04 amd64 desktop on Asus Eeepc 1015px, but it hangs on booting. The last message is 'Started User Manager for UID 120'.  I managed to boot up in recovery mode and finished the installation with 'sudo apt-get upgrade', but nothing has changed.  Does anybody know how I can tackle it?  Thanks in advance, Newton.

I can only see my desktop pic upon login and that is because unity plugin isn't enabled.  I tried ccsm, but there is no way for me to apply changes so the unity plugin remains disabled. I also can't close windows because the bar at the top of each window is not there.

How do you start ubuntu unity 3D with the dash open? This is so that I can get things done fast. I would like to log in to my desktop with a full-screen dash without having to click the Ubuntu dash button.

What happened  I was working on my laptop while it upgraded from 15.10 to 16.04 (which I admit was a mistake) when suddenly the Unity overlay disappeared and the only thing on screen was the Firefox browser window. I switched to a new terminal, logged in and tried to run sudo service lightdm restart but instead of restarting correctly, the screen started turning on and off repeatedly, which freaked me out, so I physically turned off the PC.  Long story short: I forced a shutdown halfway through the Ubuntu upgrade.  Ever since, any attempts of logging in normally have been met with a solid black screen and the idle whirring of the CPU fan.  What I have tried  I have tried the recovery mode boot up, but no luck (The log does greet "Welcome to Ubuntu 16.04 LTS!"). I tried out each option that seemed useful:   dpkg goes through the packages as advertised, but strangely enough it always locks up on some Braille package until I do Ctrl+C, at which moment it spouts some error messages and then I think throws me into the normal boot. failsafeX results in a similar situation to the normal boot: a black void. fsck says the single partition I have is a-ok. grub seems to get a bunch of stuff. Don't know if it searches locally or fetches from the internet. network didn't work I think.   I tried following  but couldn't do the sudo part because the filesystem was mounted as readonly. So I ran fsck which mounts as RW and tried again.   This time, after running apt-get autoremove it went through many packages (Setting up foobar (X.Y.ZubuntuN) ...), sometimes installing packages, which I assume is the usual behavior. One thing to note though is it kept getting stuck several times, so I had to Ctrl+C it out of processing the current package. It finally ended on "Processing was halted because there were too many errors.".  While  seems to mention some of the graphics problems I've been experiencing... I have Intel HD Graphics, not Nvidia. I'll keep looking into it.

I have a problem with Ubuntu 13.04.  I cannot log in to my account. I put the right password but there is an endless loop. (if i put wrong pass, it says "Invalid password..."). Also, it doesnt show the small drop down menu with choices "Gnome fallback, Default, etc.."  If i login as guest, the desktop is clear, no bars, no menus, anything. Just right clicks works only.  I have already try  solution ( chown username:username .Xauthority ) but there is no "Xauthority" at ubuntu 13.04. (?)  Is the problem about lightdm? Also, i tried sudo dpkg-reconfigure lightdm but it soesn't work.  I use the recovery mode (root command shell or something like this) in order to try the above commands.  Has anyone a solution?  Thank you.

A few days ago I turn on my computer and when Linux started, the icons on the desktop look black, I tried reinstalling the desktop, the gnome-shell, updating but nothing happens. I attached a picture with the problem.

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

After installing Ubuntu 11.10 on a new computer everything worked fine for a few weeks and now suddenly when starting up Ubuntu I get a blank purple screen with no "Ubuntu" splash and the 5 dots but the system does start up.  What has happened to loose the Ubuntu splash screen?  Also, I've checked in the Grub startup and it has quiet splash in the Linux line.   I have an ATI Radeon 5450 graphics card which needed nomodeset to be added to the Grub line when booting for the first time off the install CD but now this line has disappeared from the grub startup.  Can anyone help?

I upgraded my ubuntu from 11.04 to 11.10 via mounting the latest alternate CD image released on Oct. 13 as the final standard version and running the cdromupgrade prompt successfully, with full latest upgrades installed before ending the distribution upgrading process and rebooting. After reboot, the new lightdm showed up as expected, and I could choose the login shell from a menu containing "ubuntu", "ubuntu 2D", "recovery console", "kde workspace", "cairo-dock with effects", "cairo-dock without effects", etc. next to my name which corresponds to my username.  HOWEVER, for example, I chose "ubuntu" (as the default selection) and input the correct (if not correct, the lightdm would ask you to input again, but it did not do so, I have tried) password and entered. The screen splashed to the black screen of the background text interface of gdm for a very short interval and then returned back to the interface of lightdm without my user account logged in and appeared as if I have not done anything on the laptop. Neither could I log in as a guest user as the same black screen splashed and lightdm reappeared.  Before the upgrade, I could run gnome 2, kde, unity all quite well on the laptop, but the status quo is that no one from the menu prompt beside my name can log in to my account, including the "recovery console".  Actually I can switch to the ttys and log in my account with my username and passcode normally, as can run all commands in the tty (I am currently doing this). I can also act like a superuser via the "sudo" command and get a # prompt via the "sudo -i" command, with the correct password, no problem.  In the root prompt, I can run "service lightdm stop" and "startx" to a root unity UI successfully (that is the way how this passage comes out), but in the $ prompt, after running "service lightdm stop" and "startx", it simply appears "No protocol specified" endlessly and no GUI appears.  I found the package "gnome-shell" not fully installed and fixed it, but it did not help, simply resulting in a selection in the menu which cannot access my account as its companions.  I have made all the packages in my laptop up-to-date and no updates should be installed.  My device is ThinkPad X61, with all its functions running well on all previous ubuntu distributions since 10.04 LTS. I had upgraded my os from 10.04 LTS to 10.10 in the way I performed today without any unexpected results one year ago.  I suspect it is the newly integrated lightdm that set these obstacles, and I want to get this bug fixed, please help!

I'm getting no Dash / Launcher after I login. This started after an update through the Software updater. Please help to fix ... I've already lost a day trying different options posted on askubuntu.com. Nothing worked.  Got to the terminal via Ctl + Alt + F1 and logged-in successfully.  Here are the logs: .xsession-errors Script for ibus started at run_im. init: unity-panel-service main process (2315) terminated with status 1 init: indicator-printers main process (2459) terminated with status 1 init: unity-settings-daemon main process (2300) terminated with status 1 init: upstart-dbus-session-bridge main process (2293) terminated with status 1 init: hud main process (2304) killed by TERM signal init: indicator-bluetooth main process (2446) killed by TERM signal init: indicator-power main process (2448) killed by TERM signal init: indicator-datetime main process (2451) killed by TERM signal init: indicator-sound main process (2453) killed by TERM signal init: indicator-session main process (2483) killed by TERM signal init: indicator-application main process (2486) killed by TERM signal init: Disconnected from notified D-Bus bus   UPDATE (Jun 8, 2014):  Okay, I have reset unity, but I cannot login normally via the login screen. Steps I follow: 1. Login screen -&gt; blank ... No dash / no launcher / No Status (Notification) Bar on top 2. Ctrl+Alt+F1 to bash terminal 3. export DISPLAY=:0 4. unity-tweak-tool --reset-unity (This does not complete, blocks on OpenGL) 5. I anyways continue to by doing: Ctrl+Alt+F7. 6. Launcher &amp; Dash look good. But there is (a) No Status / Notification Bar on top 7. Continuing to work this way. Haven't logged out since.

Recently I installed gnome-desktop in my Unity Ubuntu 16.04.Now I want to set my Unity desktop environment as default.   I installed Gnome by using these commands :  sudo apt-get install ubuntu-gnome-desktop   then chose gdm3 as default.  Now, I have searched on internet how to do so, one of them say this :  sudo /usr/lib/lightdm/lightdm-set-defaults -s ubuntu   But it throws error saying :     sudo: /usr/lib/lightdm/lightdm-set-defaults: command not found   I'm using ubuntu 16.04.

solution doesn't work. I'm using Guest account right now.  I was just working on VirtualBox and listening to some music with Rhythmbox when suddenly my computer became laggy, and seconds later, everything disappeared except my cursor and wallpaper. I ran terminal using CTRL+ALT+T and typed startx, sudo startx, and the last one sudo shutdown -h now. After booting up my computer again I could not login to my user account, after typing my password and hitting enter, black screen for 2 seconds, and login screen again.

My PC was working yesterday without any problem. I shut it down and tried to open this morning. It prints out these messages on the black screen:  systemd-udevd[713]: failed to execute '/bin/systemctl' '/bin/systemctl start --no-block nvidia-persistenced.service': No such file or directory  systemd-udevd[852]: failed to execute '/bin/systemctl' '/bin/systemctl stop--no-block nvidia-persistenced': No such file or directory   It then continued with the login screen. I entered my password and pressed enter. It waited for a while and the login screen reappeared again.  How can I fix the problem?

I've done a clean install of 18.04 and I can't open desktop folders, not even the desktop trash can. Anybody else had this issue? I click on the desktop folders (double click) and nothing happens.  Strange enough, I can open  them when using Nautilus and going to home\stackinator\desktop\ or whatever the path is (can't remember at this point).
