Ubuntu 20.04 LTS get stuck at logo screen

Question

I am using Ubuntu from last month, but today I tried to boot it and it get stuck at the logo screen I also disabled fast startup and secure boot ,also I add nomodeset but nothing actually improved.

Answer 1

Yesterday's software update in Ubuntu 20.04 updated nvidia-driver-450 to nvidia-driver-460. Yesterday's software update also updated all of the Nvidia 450 series packages from 450 to 460. The following commands will install the recommended proprietary Nvidia graphics driver in Ubuntu 20.04.

1. Remove all the nvidia packages.

   sudo apt update
   sudo apt-get remove '^nvidia'
   sudo apt autoremove
   

2. If you have added an Nvidia PPA to /etc/apt/sources.list remove that PPA by prefacing its line in sources.list with a # to comment it out. Run sudo apt update to refresh the list of available software.

3. Reboot with sudo reboot

4. Run the following commands to install the recommended proprietary Nvidia graphics driver.

   sudo ubuntu-drivers install
   sudo reboot
   

If automatically installing the recommended proprietary Nvidia graphics drivers doesn't work, try reverting them back to an earlier version like nvidia-driver-450 or nvidia-driver-435.

If the above 4 steps don't work, the other possibility is that the boot problem is caused by a kernel update in Ubuntu 20.04 that has generated several questions at Ask Ubuntu in recent days and is answered in this answer.
