After Kernel 5.11 update, computer won't boot? Related to nVidia drivers. (Kernel 5.11.0.25.27~20.04.10)

I think I found a solution based on some other experience:

  • apply fix for 5.11 kernel:

    1. Boot in first available kernel that is working (for me it is 5.8.0.59)
    2. Add repository: sudo add-apt-repository ppa:kelebek333/nvidia-legacy
    3. Apply fix: sudo apt install xorg-modulepath-fix

Change from Nvidia to nouveau drivers.

Try to reboot with 5.11.

For me this was working combination.

Note: Definitely there is some bug with lib32gcc1 and libgc6xx and their incompatibility with this and later kernel updates. We have to wait for this fix for nvidia drivers.
