Comment 1 for bug 1993019

I saw the same issue. I performed fresh Ubuntu 22.04.1 install on Dell Precision 7540. First attempt I immediately installed proprietary drivers by enabling this third party option in install dialog. After this Software & Updates do not allow update. All options are greyed out and cannot be enabled. There is a message "This device is using a manually-installed driver"

Second attempt I installed without proprietary drivers / with third party disabled. After installation and reboot Software & Updates does allow me to select a proprietary driver. There is no longer a message "This device is using a manually-installed driver"
