Unfortunately i have the same problem on Ubuntu 22.04 LTS I could’ve find a solution but as a temporary work around you can do the following: 1- in GRUB boot screen choose „Advanced options for Ubuntu“ 2- choose an earlier kernel version to boot from (not recovery mode) That worked for me as i can‘t boot to Ubuntu GUI otherwise, and i do it every time i want to use Ubuntu

I just upgraded my Ubuntu to the latest version and had the same problem. It seems it comes from my Nvidia card and their drivers. So I went to the "Advanced options for Ubuntu", chose the just new version (with recovery), and then: 1) selected to do a "clean" (which uninstalled the old Nvidia drivers and then updated them), and 2) selected "dpkg" to fix any corrupted packages (that it found out to be the same old drivers). Once 1) and 2) finished, I just verified everything by re-doing 1) and 2) again (this time nothing new was found and everything was up to date). I finished by rebooting and now my Ubuntu is working fine ;-)

I faced recently same problem with new fresh install of Ubuntu 22.04 in my GPU system of Nvidia RTX 4070ti. Basically it is problem with missing Nvidia drivers. Follow below given steps to resolve the issue -

  1. Connect a wired U.S.B internet connection (Mobile hotspot) to your PC or you can connect it through CAT ethernet cables. This assumes that Wi-Fi drivers are not properly installed in the new system. If they are installed, then you can skip this wired ethernet connection step and connect to your WiFi network through terminal which we will be opening in step 5.

  2. Restart your PC and while booting, press Esc key multiple times Or keep Left-Shift button pressed while ubuntu boots to open grub menu. Select Advanced Options for Ubuntu.

  3. Select the topmost (recovery mode) option.

  4. Use arrow keys to navigate to "network Enable networking" and press enter. Select yes if asked for confirmation.

  5. Use arrow keys to navigate to "root Drop to root shell prompt" and press enter. Press enter again if asked for confirmation in terminal.

  6. If you haven't used wired U.S.B/ Ethernet as in step 1, then connect to your WiFi network here in terminal. If wired network is connected then continue to step 7. Refer this for connecting to WiFi network in terminal - Connect to WiFi network through Ubuntu terminal

  7. Type command - ubuntu-drivers list. This will list all possible drivername options you can install for your graphic card.

  8. You can automatically allow ubuntu to figure out best option using ubuntu-drivers autoinstall or install a specific driver using apt install drivername. This will download and install the Nvidia driver from the network.

  9. Give following commands -

    apt-get update --fix-missing

    apt-get upgrade

    reboot

Now you should be able to reboot properly into ubuntu. Basically we are opening terminal in safe mode of Ubuntu and Installing the drivers through terminal over wired/wireless connection in above steps. Please upvote if it helps!
