1. Preparation before installation: special instructions
1. Update PCI ID
Since the current kernel version used by ubuntu 18.04 is 4.15.0, the newer graphics card has not been updated synchronously, so we need to manually update the supported PCI ID.
1) Enter in the terminal: sudo update-pciids
2) Check whether the command is executed successfully: sudo cat /usr/share/misc/pci.ids | grep -i rtx
The output should include a GeForce RTX 2080 Ti
3) Check whether the currently inserted RTX2080Ti is recognized correctly: lspci | grep -i nvidia
