I would like to install the latest Nvidia driver (455), but unfortunately it does not work. I get the following errors:
nvidia-installer log file '/var/log/nvidia-installer.log' creation time: Mon Nov 2 09:23:23 2020 installer version: 455.38 PATH: /home/merlin/.local/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:/var/lib/snapd/snap/bin nvidia-installer command line: ./nvidia-installer Unable to load: nvidia-installer ncurses v6 user interface Unable to load: nvidia-installer ncurses user interface Using: nvidia-installer ncurses v6 user interface (widechar) -> Detected 12 CPUs online; setting concurrency level to 12. -> The file '/tmp/.X0-lock' exists and appears to contain the process ID '1326' of a runnning X server.

For further details, please see the section INSTALLING THE NVIDIA DRIVER in the README available on the Linux driver download page at www.nvidia.com. ERROR: Installation has failed. Please see the file '/var/log/nvidia-installer.log' for details. You may find suggestions on fixing installation problems in the README available on the Linux driver download page at www.nvidia.com.
i currently have the 440 driver installed.
it seems difficult to upgrade the driver
