D3vil0p3r [1] filed an orphan request for nvidia-340xx-utils [2]: Package seems not maintained for 5 years and comments are not followed. Furthermore, the -utils package erroneously is in conflict with nvidia-340xx-settings package. Indeed 114-119 lines must be removed and nvidia-340xx-settings must be added as optional dependency (as occurs for -390xx and -470xx related packages)
