Nvidia issue

HI

please help me with this error in ubuntu20

we have installed latest driver but not working

uidd7623@ozd2085u:~$ sudo nvidia-smi
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.

Please check this attached file

blacklist the nouveau driver.

how to do that

https://linuxconfig.org/how-to-disable-blacklist-nouveau-nvidia-driver-on-ubuntu-20-04-focal-fossa-linux

Actually I just noticed the initramfs update is only in the picture.
So don’t miss out on updating the initramfs after blacklisting:
sudo update-initramfs -u -k $(uname -r)

sudo bash -c “echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf”
sudo bash -c “echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf”

updated intiramfs and rebooted pc

i have checked with nvidia-smi

uidd7623@ozd2085u:~ sudo nvidia-smi sudo: nvidia-smi: command not found uidd7623@ozd2085u:~

getting command not found

You didn’t get that it your initial post.
What did you do? Did you uninstall the nvidia driver?

no i didnt get that in my initial post

i have followed that link,after that getting command not found

i have not unistalled any nvidia

what does dpkg -l|grep nvidia show?

i have installed driver again,disabled noveau driver.

now getting nvidia smi failed error

so yes installed.
create a new bug report.
Also try to post in a readable way. With line breaks intact. Use the quote formatting in the reply box.

is this file unreadable format???

Is this the same file as before?
nouveau is still loaded and the kern.log is full of these:

i have generated again that file,after disabling nouveau driver

can you please suggest any other solution

To reduce the log size, pleas remove the kern.log
sudo rm /var/log/kern.log
Then install the nvidia driver
sudo apt install nvidia-driver-460
and reboot. Immediately after reboot, please create a new nvidia-bug-report.log.

Edit: typo in command
