i have a notebook hp (G4) with a pci wifi card who need a non-free software rtl8723be driver
i use this with a usb wifi-pen free (ar9170), but is possible to have thertl-driver in a new kernel-libre in the future??

Most non-Atheros WLAN cards do have free/libre drivers, and I believe that these free/libre drivers do exist in the kernel.

But non-Atheros cards can't work without non-free firmware. In other words, without non-free firmware, those free/libre drivers are useless.

Some Realtek WiFi cards do work without non-free firmware. A friend of
mine has an rtl8188ee, which is functional, though not always reliable,
with Trisquel. I have not tested the rtl8723be, so I cannot promise
that this will work, but you might try installing the latest
Linux-libre.

If that doesn't work, please tell us the exact model of your laptop.
That will determine what your other options are.

He said that his notebook belongs to the HP G4 series.

Unfortunately, HP notebooks are heavily encumbered by whitelist restrictions. Unless this series has ath5k/9k cards approved by HP's firmware, it's impossible to replace the WLAN card with a free/libre one.

Do you have a list of which laptop manufacturers do and don't impose
whitelist restrictions? I know that HP and Lenovo do. Are there any
who don't?

Also, have you yourself written or considered writing any documentation
or guides about migrating to free software and free-software-compatible
hardware? You have a lot of knowledge, and it has been helpful in many
threads here, and I think there would be a lot of value in an organized
consolidation of that knowledge.

If (information on) legacy hardware is still important to free/libre software users, I'd like to summarize something, but mainly about legacy ThinkPads.

I haven't used many computing devices other than ThinkPads, and have been troubled by the whitelist restrictions for many years. Yet there are some manufacturers (or at least part of their product lines) don't impose restrictions on WLAN cards.

For example, I once tried Dell Latitude and Alienware series, as well as Samsung 9-series. They seem don't have whitelist restrictions, so I could install ath9k cards on them. Please note that some ultra-portable notebooks, like Samsung 9-series Haswell models, use integrated WLAN cards (i.e., soldered on the board) so that you can't possibly replace them. I once found a Samsung 910S3G (Haswell ULV but without Boot Guard, on-board Atheros AR9565). Its integrated WLAN is a free/libre one, but too weak (single antenna, single band). I didn't purchased it but selected 900X3D with IvyBridge ULV and replaceable WLAN card.

BTW, one major weakness of my Samsung 900X3D (and other IvyBridge 9-series) is that it uses HM75 chipset and therefore doesn't have native USB3.0. This causes certain compatibility issues with USB booting. Relatively few USB 3.0 flash media are bootable on it. Some of them may even cause POST fail.

Then it probably needs a proprietary program in order to function, which is why it does not work. It should be possible to confirm this by doing:

dmesg | grep -i deblobbed

And then share the output.
