Graphic card detection problem

Graphics / Linux Linux
#1

Hi everyone,

My problem is that my Nvidia Graphic Card is not recognized since a few days.

I’ve got this return form lspci, I don’t understand why my Card is shown has that
lspci -vnn | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation UHD Graphics [8086:9bc4] (rev 05) (prog-if 00 [VGA controller])
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation Device [10de:1f95] (rev a1) (prog-if 00 [VGA controller])

There is my bug report log
nvidia-bug-report.log.gz (96.3 KB)

Moreover, in Software & Updates, I have this return

OS: Ubuntu 20.04
Graphic Card: Geforce gtx 1650TI
I checked different topics who seems to have the same problem than me but I don’t find any solution.
I’ll be thankful for any kind of help.

Please try running
sudo prime-select nvidia
and reboot.
Also, please try if you can manually load the driver
sudo modprobe nvidia

Nvidia driver no longer loading on Ubuntu 20.04

Prime-select nvidia didn’t work.
The other command return :
modprobe: ERROR: could not insert ‘nvidia’: Key was rejected by service

sudo dkms remove nvidia/460.39 --all

This command returns :
Error! There are no instances of modules: nvidia
460.39 located in te DKMS tree.

I don’t know if i have an instance of this module, and what version is mine, do you know how can I get the information ?

Please post the output of
dkms status

#7

This returns nothing

#8

Please try adding the graphics drivers ppa and re-install the driver from there.

According to this:
https://askubuntu.com/questions/1323913/all-resolution-options-except-1024x768-gone-after-upgrade-to-ubuntu-20-04-2-lts
there should be new ubuntu updates released that fixes the situation.
