my os is Ubuntu 18.04.
I want to enable NVENC encoder for OBS recording. I followed this tutorial: https://scottlinux.com/2016/09/12/how-to-enable-nvidia-nvenc-for-obs-in-linux/
But on step 2, I made a mistake. I installed Cuda from ubuntu repository, not just copy Cuda.h.
And after I installed Cuda from repository (apt get cuda). I rebooted my laptop, and then I couldn't start the GUI. I can start the GUI again after to uninstall Cuda, but I also lost my nvidia driver when uninstalling cuda.
Then, I tried reinstall the nvidia driver base on this guide: https://www.cyberciti.biz/faq/ubuntu-linux-install-nvidia-driver-latest-proprietary-driver/ My vga is Nvidia 930MX and I installed nvidia-driver-435.
Nothing error when installing the driver. But when I reboot my laptop, I could't start GUI again. I tried to another version nvidia-driver-390, nvidia-driver-430. But nothing works.
Now, I decided to use Intel HD for emergency purpose. But on startup (dmesg log), I got this error:

I want get back my nvidia driver. Anyone can solved this proble or given a suggested solution.
UPDATE 1: Now I solved nvidia driver error problem with following step.
- Remove all nvidia package and reboot
sudo apt purge nvidia-driver-440
sudo apt autoremove
- Install nvidia driver from run binary, that's available on nvidia website.. If there are dkms error, run:
sudo apt install dkms
If there are error unable to load the 'nvidia-drm' kernel module. Remove xorg.conf
sudo rm /etc/X11/xorg.conf
Then install the binary nvida driver.
I am waiting your help to find a best way to enable nvenc encoder on OBS.
