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.
blacklist the nouveau driver.
how to do that
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
idd7623@ozd2085u:~$ dpkg -l|grep nvidia

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
