Nvidia issue

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

May 4 11:16:58 ozd2085u kernel: [ 16.944027] nvidia-nvlink: Unregistered the Nvlink Core, major device number 237

May 4 11:16:58 ozd2085u kernel: [ 17.318248] NVRM: No NVIDIA devices probed.

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

If remove kernal.log file, will it system effect anything

No, it’s just a log file that’s flodded with errors. Will be recreated on reboot.

nvidia-bug-report.log.gz (171.6 KB)

Please create /etc/modprobe.de/blacklist-nouveau.conf

blacklist nouveau
blacklist nvidiafb

and run

sudo update-initramfs -u -k $(uname-r)

still same error getting

Please reboot and instantly create a new nvidia-bug-report.log

I don’t know what you’re doing but you’re definitely not doing things correctly. Nouveau is still not blacklisted, the log was taken after being up for 30 minutes, don’t know if you rebooted at all. Also, you’re booting into the wrong kernel, please choose 5.4.0.70 on grub menu.
For an easier method to blacklist nouveau, please set kernel parameter
nomodeset

i have tried with same settings whatever you have provided, after reboot done given logs to you,

we are using customized image for our organization,can you please suggest what we do next

how can we add this kernel parameter at grub page

It’s in the given link, scroll down, read and follow the instructions in the chapter “Permanently Add a Kernel Boot Parameter”
Regardless of that, did you boot to the correct kernel meanwhile?

we have only one kernel listed here

According to your logs, you have 5.4.0.66 and 5.4.0.77 installed, at least the nvidia driver was installed for that.
Since you said “we are using customized image for our organization”, do you use PXE boot, i.e. boot the image over network? Then the network image has to be modified, i.e. the driver installed.

this kernel we are using
5.4.0-66-generic

setted kernel boot parameter perminently under /etc/default/grub

after rebooted this file got vanished, there is no line whatever i have modified there

Then you’re using either using network boot or the system’s config is central managed so you can’t change your boot config. Please ask the person responsible for managing your network/devices.

hmm ok we cant change this boot file then,it not possible to modify network boot.

if we boot with other kernel will it work

All changes you make will be reverted by your companies’ management software. I can’t help you with that, only the person responsible for it can.
