After I tried nvidia-dkms driver and uninstalled it, nvidia card is not showing at all anymore in lspci output. Only Intel graphics is detected. Interestingly lspci shows Nvidia card when I boot Manjaro from USB. Nvidia drivers are not able to detect it either. Tools like lshw don’t see it as well. How to enable it also the installed system without reinstalling whole system?
I have Dell XPS with Nvidia RTX 3050 Ti.
provide formatted output from:
inxi -Fazy
journalctl -b0 -p3 --no-pager
sudo dmesg | grep nvidia
mhwd -l && mhwd -li && mhwd-kernel -li
pacman -Qs nvidia
Hi @brahma
sudo dmesg | grep nvidia: no output
PCI devide is 01:00.0 that have dissapeared from installed system. When it happened I was using 5.15 kernel. Installed kernel 5.18 and linux518-nvidia but still doesn’t show Nvidia card.
so its not detected in 5.15 and 5.18 kernels?
also output from:
ls /etc/modprobe.d
and post it here, click this icon in editor: </>
That’s right.
$ ls /etc/modprobe.d

you have it blacklisted via the envycontrol… uninstall the envycontrol:
pamac remove envycontrol
reboot and see if its detected
I appreciate your help, @brahma .
I played with envycontrol earlier today and that might have blacklisted nvidia.
Unfortunately I had broken my install with pci rescans or something before posting here and I was not able to boot anymore (and colorless boot log gave no hope) and had to do reinstall anyway. I believe that removing envycontrol blacklist file would have helped (envycontrol was already uninstalled). Lesson learned in a hard way.
yes if it was already uninstalled, then removing the leftover blacklist file would probably helped…
