Do you know why you have libnvidia-cfg1 (from the current, not the <br>
legacy driver)installed? That probably stems from the attempt to install <br>
nvidia-settings for the current driver.<br>
(You also have libnvidia-legacy-390xx-cfg1 installed.)<br>
<br>
If you uninstall libnvidia-cfg1 everything should be back to normal again.<br>
