I has created a USB boot from Ubuntu 20.10 image and on load it crashes. The mouse's pointer has freeze and Ctrl+Alt+F1 doesn't work.

I just changed the USB image but didn't work. I came back to Ubuntu 20.04, it's fine.

I need help to solve this problem.

  • What is your end goal? Why couldn't you stay with 20.04? – emk2203 Oct 29 '20 at 08:10
  • My goal is install Ubuntu 20.10. why I need to stay with 20.04? – Wagner Serra Oct 29 '20 at 12:46
  • Then, when you have a working 20.04, why don't you just upgrade it with update-manager or do-release-upgrade? Necessary steps are for example here: https://linuxconfig.org/how-to-upgrade-ubuntu-to-20-10 – emk2203 Oct 29 '20 at 18:37
  • It was my first trying. After upgrade and reboot, It has freezing. Than I try out a full instalation from a USB drive but he Ubuntu freezing on first screen. – Wagner Serra Oct 29 '20 at 21:56
  • the cause of freeze is the keyboard/touchpad is not recognized by Ubuntu 20.10.I tried use bluetooth keyboard and mouse and works. But, how to solve this after installation? – Wagner Serra Nov 18 '20 at 13:23
  • Post another question 'keyboard/touchpad is not recognized by Ubuntu 20.10', with information about laptop make/model, also the output of sudo dmesg | grep 'PS/2\|keyboard\ as' from a running sytem. That might help to get answers. – emk2203 Nov 19 '20 at 14:24

  • I would love to help you, but I have no experience with this system. You really need to put this into a new question, so that others who might know more can see it.

    You could try to boot with i8042.nopnp as kernel boot parameter, but I doubt this helps. https://askubuntu.com/questions/19486/how-do-i-add-a-kernel-boot-parameter.

    Maybe also look at https://itectec.com/ubuntu/ubuntu-keyboard-uunresponsive-after-resume-from-suspend/

The problem was solved by downloading the kernel 5.8.0-31-generic.
