Failed to start NVIDIA Persistence Daemon on ubuntu 20.04

Hello nvidia community,
I have this problem with my acer aspire f15 running ubuntu 20.04
My graphic card is Nvidia Geforce GTX 950M
So i have this problem for so long time and it start to bother me since it causes my computer behaving in such unexpected way like for example:

  • Note able to wake up from sleep mode when I open my laptop screen (it was working when I have different set up)
  • A havy load on cpu due to systemd-udev not able to load nvidia modules on the kernel ( I did some research on that but I unfortunately not able to fix that by my self)
  • Even trying to completely remove nvidia driver and reinstall it again didn’t solve nothing.

So I thought this is the best place to post my problem here.
And this the report genertaed by running nvidia-bug-report.sh
nvidia-bug-report.zip (3.7 MB)

Finally I solved the problem
And this is what I did:

  1. Completely removed currently installed nvidia driver
  2. Installed lastet driver from ubuntu gui Software&Updates window
    At this point still the issues remain the same so I did other steps:
  3. Blacklisted nouveau driver
    Still didn’t work, but then realized that I need to blacklist another driver which is nvidiafb so I did this:
    4.sudo nano /etc/modprobe.d/blacklist.conf and added this line

blacklist nvidiafb

After that reboot and every think now is WORKING!!!
hope this will help someone else.
