I followed the instructions on this link to attempt to install NVidia drivers (nvidia-driver-396) on my ASUS GL-553VD, with NVidia GTX 1050. After building was complete, these error messages popped up.
nvidia: Running module version sanity check. Error! Module version 396.54 for nvidia.ko is not newer than what is already found in kernel 4.15.0-48-generic (430.09). You may override by specifying --force.

nvidia-uvm.ko: Running module version sanity check. - Original module - No original module exists within this kernel - Installation - Installing to /lib/modules/4.15.0-48-generic/updates/dkms/
Then, the installation finished. However, upon reboot, through multiple checks (Settings-Details-About, lsmod, nvidia-settings, nvidia-smi) I determined that intel integrated graphics was still being used. Since I have made multiple attempts to install various drivers, as well as attempted to install through the run file on the official site, I suspect that the failure could be because of interference. None of my attempts to install drivers have been successful. However, installing drivers has helped in that while before I could only see a black screen unless I booted through secure mode, now I can use Ubuntu properly except for my graphics card. How do I install drivers and enable my graphics card?
