1. I download local installer CUDA run file from Nvidia.
2. I have changed my runlevel to multi-user (3) with
systemctl set-default multi-user.target
3. I rebooted to terminal only mutli-user runlevel
4. Trying to run ./cuda_10.2.89_440.33.01_linux.run few times, but in /var/log/nvidia-install.log I have seen X server still run.
5. Then I found in NVIDIA instruction I can kill X Server and remove lock file.
kill <process_id>
rm /tmp/.X2.lock
6. After resolve xserver lock I have a message in nvidia-installer.log that Nouveau driver is disabled and I need to reboot to run installation again to replace driver.
7. I repeated the trick with killing XServer process and lock file remove, I successfully install all Nvidia driver, CUDA Toolkit 10.2 and samples.
8. I changed runlevel back to grapical
systemctl set-default graphical.level
9. I rebooted to DE to check cuda samples works.
