Why aren't proprietary drivers in use?

Gary Highberger

DUT: HP Laptop 14z-fq000 20.04, single boot, MOK secure boot is enabled, an Internet connection was available during the installation (Ethernet to USB C)

I simply booted 20.04 from a thumb drive and then selected erase and install and followed the instructions and lastly updated to the latest 20.04.

Display and WiFi and Bluetooth and everything I've tried so far work perfectly.

I'm a bit worried however because under "Additional Drivers" it says (Realtek Semiconductor Co., Ltd.) "This device not working" and also "No proprietary drivers are in use".

Why aren't proprietary drivers in use?

Is there any corrective action I should take?

Many thanks, Gary

HP Laptop 14z-fq000 is AMD with a RADEON graphics card so no 3rd party there (that driver got cancelled by amd). Hmmm can't find the chipset for the NIC Realtek Wi-Fi 5 is all I could find. That might need some attention. See https://askubuntu.com/questions/1344184/realtek-rtl8852ae-issue-on-lenovo-legion-5-pro-16ach6-ubuntu-20-04 for a long thread on this. Change the numbers to what you have (commands are in the question). "Realtek Semiconductor Co., Ltd.) "This device not working" is probably fixable and might be due to a mismatch in the driver database Ubuntu uses (too new or too old)

The reason that no prprietary drivers are in use is that your wireless device doesn't require proprietary drivers. All Realtek devices that I am currently aware of use free and open-source drivers. Notably, the entire code may be read freely on various github sites.

The only devices that I am aware of that require proprietary drivers are Broadcom. You have no Broadcom device.

No corrective action is required.

The statement that "This device not working" is simply incorrect. The Additional Drivers utility often shows the same incorrect warning.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
