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.
nvidia-bug-report.log.gz (11.3 MB)
Please check this attached file
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.
nvidia-bug-report.log.gz (11.3 MB)
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
