The problem is that when I log in, the desktop appears, everything appears normally, but I can't click on anything. While I am at the login screen, I can click and write my password, but after that I can't do anything else except moving the mouse. Ubuntu 18.04.

Found an post in that anyone said it might be problem with xorg and this as solution:

apt install xserver-xorg-input-all

Tried it, didn't help. I'm not sure if it even installed anything.

If it's important, last time that it worked was yesterday while I was trying to install some extensions.

blkid

cat /etc/fstab

dpkg -l *nvidia*

  • You have a problem with a GNOME extension. Do you know how to physically move/remove extensions when you can't work in your own login? It involves booting to recovery mode. Or... do you have any other admin accounts on this system? – heynnema May 02 '19 at 18:11
  • I got Kali linux on the same machine, runned it and removed everything that i put in the extensions folder. Tried to boot ubuntu, and the problem still exist – Alex Kalaidjiev May 03 '19 at 10:10
  • Edit your question and show me ls -al ~/.local/share/gnome-shell/extensions. Also, what video card and driver do you have installed? Lastly, on the login screen, after selecting your username, click on the cog wheel icon, and tell me which environment is selected... it should probably be "Ubuntu" or "Ubuntu on Xorg". – heynnema May 03 '19 at 12:24
  • http://prntscr.com/nk033b Sorry for the image, hope it helps. Doesn't know how to get screenshots in that situation.

    Video card: MSI GeForce GTX 1050Ti. Driver: i think i never tried to install/modify the drivers from the system installation.

    The environment is ubuntu. There is also ubuntu on wayland as option.

  • There's only one extension there, and it's pretty harmless. However, in your screenshot, I see another major problem. Edit your question and show me sudo blkid and cat /etc/fstab. Tell me what version Nvidia driver you have installed dpkg -l *nvidia*. Use imgur.com for screenshots, if you like. – heynnema May 03 '19 at 16:33
  • Done. Again, sorry for the quality. – Alex Kalaidjiev May 03 '19 at 16:59
  • I made a minor edit to the sdb1 UUID in my answer. – heynnema May 04 '19 at 12:38
  • status update please – heynnema May 05 '19 at 02:35
  • Didn't work. i reinstalled the whole system and rebuild everything i had done form 0. But thanks anyways ! – Alex Kalaidjiev May 05 '19 at 13:14
  • Did my procedure break down somewhere, or did it go ok, but the problem persisted? – heynnema May 05 '19 at 14:47
  • Everything from your procedure gone fine, it fixed the problem with the swap but the major problem didn't been solved. – Alex Kalaidjiev May 05 '19 at 15:41
  • Did the reinstall finally fix the problem for you? – heynnema May 05 '19 at 16:54
  • Of course, fresh install, everything from the old system is removed. – Alex Kalaidjiev May 05 '19 at 17:25

You've got a problem with your swap partition.

Screenshots or images make it a little difficult to give a 100% complete answer, but I'll give you the basics and that should be enough.

The /etc/fstab has a line where it tried to mount swap. It fails because the UUID that ends in c932 is incorrect. We have to edit /etc/fstab and replace that incorrect UUID, with the UUID that we see in the sudo blkid command... using the /dev/sdb1 UUID that ends in 18cf.

Boot to recovery mode and enter this command(s):

sudo mount -o rw,remount / # assure the disk is r/w

sudo blkid | grep sdb1 # show us the correct UUID

copy this UUID to the clipboard

sudo pico /etc/fstab # edit fstab

replace the bad UUID on the swap line, with edit/paste

control+o and return to save the edit

control+x to exit the editor

reboot # reboot the computer
