I bought a computer a couple of months ago wasn't able to make it work so tried again, here is the spec:

When trying to install I got these error messages:

  • nouveau : unknown chipset
  • PCIE bus error: severity=corrected, type physical layer

After installing I was able to reach the login screen, when I move my mouse over my user name to log in, mouse movements are choppy. and after i enter password (also choppy typing) I return to the login screen.

I've spent a lot of hours on this and no success.

Edit:

  • tried to install for desktop 18.04.03 and 19.10
  • I didn't enable HWE, just downloaded from the official website created ISO and tried to install
    • How do I enable HWE?

How do I make it work?

The same happened to me, that's a problem related to the NVIDIA Kernel Module failing with proprietary drivers. To solve it, do the following steps:

  • At the login screen, press ctrl+alt+f2 and login with your name and password
  • Type sudo nano /etc/default/grub (you can change nano to the text editor of your preference, but nano is Ubuntu's default text editor) to edit /etc/default/grub
  • Change the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="nomodset"
  • Update this grub edit with update grub
  • Install lightdm using sudo apt-get install lightdm
  • Reboot (you can shutdown throught the terminal with shutdown now)
  • lightdm? This is 19.10, there is no unity. lightdm has been replaced with gdm3 since 2016. – darksky Dec 5 '19 at 6:43
  • Well, at least that was the solution that worked out for me (and also for other people). However, I can try the same solution, but without lightdm to see if it still works. – victorrms Dec 5 '19 at 14:14
