I just installed a fresh Ubuntu 20.04 on my Lenovo Z580 laptop and it’s dual boot with Windows 10.

Windows 10 runs fine, but whenever I launch Ubuntu, my PC screen starts flashing continuously. The flashing screen starts from the GRUB screen and continues to when I login into Ubuntu.

I searched and tested many different solutions but nothing changed. Here are some of the solutions I tried:

  • Changing NVIDIA (Performance mode) into NVIDIA On-Demand (nvidia x-server config).

  • Changing NVIDIA (performance mode) into Intel (Power Saving mode).

  • Setting nomodeset in GRUB config.

  • Using proprietary NVIDIA drivers.

  • Reinstalling the drivers from main server.

  • Changing GRUB config to:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash drm.debug=0x1e log_buf_len=4M"

  • ...

Can anyone help me on this problem?

Here are some links which didn't give me any good news:

  • I just bought a Lenovo E15 Thinkpad and installed Ubuntu 20.04 dual-boot with Windows 10. I'm seeing frequent screen flicker-to-black too. Did you ever solve it? Thanks. – Ryan Jul 23 '21 at 16:10

    @Ryan The OP solved it by downgrading the kernel to another version, as you can see in their answer. – BeastOfCaerbannog Sep 26 '21 at 19:45
  • @BeastOfCaerbannog Thanks for the notification since I wouldn't have seen this update otherwise. – Ryan Sep 26 '21 at 22:34
