I just installed Pop_OS! 22.04 onto Framework’s 1TB expansion card, and have been booting off of it for the past couple of days. It’s been working great so far—I’ve got my desktop set up the way I like it, and I even got the fingerprint reader working no problem. However, I just cannot seem to get the brightness keys to work. I have tried turning FN lock on and off, but that didn’t make a difference. I can use all of the other important FN keys like volume, play/pause, etc. (airplane mode isn’t working, but I don’t really care about that).
I also tried running the sudo kernelstub -a blacklist_module=hid_sensor_hub command from a terminal, which I found on this Reddit thread, but that unfortunately didn’t fix it for me, even after a reboot. I even tried disabling the ambient light sensor in dconf Editor (/org/gnome/settings-daemon/plugins/power/ambient-enabled), but still nothing.
This thread in the same Reddit post seems to indicate that the issue is related specifically to 12th gen Intel, which I am running (i5-1240P).
I should also point out that I am able to adjust the brightness no problem using the menu in the upper right corner of the screen. It’s just the function keys that don’t work.
TL;DR — Has anyone figured out how to get the FN brightness keys working on 12th gen Intel running Pop OS 22.04?
Yes, I have Windows installed onto the main SSD, and Pop_OS! on the Framework Expansion Card. I didn’t wanna just jump in head first to switching to Linux, but it looks more and more like I’m gonna be making the switch. If I need Windows, I’ll just run it in a VM.
Running that command DID come back empty, so I guess the blacklist didn’t work.
This also unfortunately didn’t work. When I eventually do move over to installing Pop onto the SSD (in a non-dual boot environment), I’ll try these steps again. Thanks!
