I’ve been using my framework laptop with KDE Plasma (currently based on Ubuntu 22.04) for more than a year now, and something weird just happened to me: exemple with the F5 key: fn-lock enabled: _F5 plays music_, **fn+F5 refreshes browser page** fn-lock disabled: _F5 plays music_, _fn+F5 plays music_ Normal behavior should be: fn-lock enabled: _F5 plays music_, **fn+F5 refreshes browser page** fn-lock disabled: **F5 refreshes browser page** , _fn+F5 plays music_ As you can see, when fn-lock is disabled, it acts like the fn key is always pressed Any idea what’s going wrong ? ---

How did you enable or disable function lock? I just installed all the software updates on Fedora 37, GNOME version 43.3, and now none of the “quick actions” on the function keys work. E.g. I used to be able to press F7 to decrease the screen brightness, but now that key is just registered as a regular F7 press. Same for all of the other function keys, including volume control - they just register as function key presses rather than changing the volume, controlling media playback, etc. Even if i hold down the “fn” button then press any of the function keys, it still triggers a regular F-key press rather than activating any of the “quick actions” ---

@jean Does this behavior persist after a reboot? ---

Yup, I tried multiple time and even switched kernel (5.15 up to 6.2) ---

Ok… maybe try a mainboard reset, and if that still doesn’t work you should contact Support. [https://guides.frame.work/Guide/Fully+Resetting+the+Mainboard+State/113](https://guides.frame.work/Guide/Fully+Resetting+the+Mainboard+State/113) ---

Hi @jean , Can you try and check if it’s KDE specific behavior? try to check the global shortcut keys it’s most like on system settings, perhaps something has changed? let us know what it looks like at the moment. ---

Guys… I swear I rebooted multiple time and even removed the motherboard cell without any success But booting on a fresh Ubuntu from USB stick apparently solved the issue for me fn lock worked fine there, and now it works fine on my KDE install as well 🤷‍♂️ ---

I believe you lol… In other threads too some people are reporting transient problems with Fn keys. Usually they don’t happen often (they are really rare, for me, but they do happen), and almost always go away with a reboot, but maybe your problem was a bit different. The issue seems to be seriously looked into, so it’s possible that a future iteration of the BIOS will fix it. ---

Have the same issue: fn + action, or action buttons stopped working recently My setup: KDE neon 5.27 fn + escape to change also does not work. As of now f1-f12 buttons only work in f1-f12 mode - no actions (e.g. brightness increase) are available (no matter if I press fn or not): - tried pressing fn + f1-f12 - tried pressing just f1-f12 - tried switching by fn + escape in all cases no actions are available ~~will try to boot from usb and see if that fixes the problem~~ Update: the issue is solved after reboot ---

hi @Ievgen , let us know if it happens frequently, or just a one off event. thanks. ---

Yes the problem repeats after reboot after couple days running without reboot - not sure about the root cause. E.g. not right after the reboot but couple days after. My best guess is that its somehow connected with sleep mode. I installed `evtest`, but it does show nothing when I press Fn button (both when `Fn` is not working, and when Fn is working after reboot) So it might not be the best tool for testing `Fn` stopping registering in the system. F1+Fn and F1 has not difference when this issue happens. Below, copied output from `evtest` just turn on-turn off for F1+Fn as for F1 only its identical: ```auto Event: time 1682197753.418585, type 4 (EV_MSC), code 4 (MSC_SCAN), value 38 Event: time 1682197753.418585, type 1 (EV_KEY), code 56 (KEY_LEFTALT), value 0 Event: time 1682197753.418585, -------------- SYN_REPORT ------------ Event: time 1682197753.430739, type 4 (EV_MSC), code 4 (MSC_SCAN), value 0f Event: time 1682197753.430739, type 1 (EV_KEY), code 15 (KEY_TAB), value 0 Event: time 1682197753.430739, -------------- SYN_REPORT ------------ ``` after reboot, Fn+F1 and F1 only - working correctly now: ```auto Event: time 1682197870.238866, -------------- SYN_REPORT ------------ Event: time 1682197870.650673, type 4 (EV_MSC), code 4 (MSC_SCAN), value a0 Event: time 1682197870.650673, type 1 (EV_KEY), code 113 (KEY_MUTE), value 1 Event: time 1682197870.650673, -------------- SYN_REPORT ------------ Event: time 1682197870.799744, type 4 (EV_MSC), code 4 (MSC_SCAN), value a0 Event: time 1682197870.799744, type 1 (EV_KEY), code 113 (KEY_MUTE), value 0 Event: time 1682197870.799744, -------------- SYN_REPORT ------------ Event: time 1682197872.444981, type 4 (EV_MSC), code 4 (MSC_SCAN), value 3b Event: time 1682197872.444981, type 1 (EV_KEY), code 59 (KEY_F1), value 1 Event: time 1682197872.444981, -------------- SYN_REPORT ------------ ^[OPEvent: time 1682197872.562701, type 4 (EV_MSC), code 4 (MSC_SCAN), value 3b Event: time 1682197872.562701, type 1 (EV_KEY), code 59 (KEY_F1), value 0 ``` Please share more details how I can help you debugging / testing this problem. ---

Hi @Ievgen have you tried restarting just the desktop environment? see if fn keys functions recovers? I think, just pressing Ctrl + Alt + Backspace does it, let us know if it makes any difference. ---

I tried to follow both methods, desktop restarts but fn button / multimedia buttons still do not work: ```auto killall plasmashell kstart5 plasmashell ``` or ```auto kquitapp5 plasmashell kstart5 plasmashell ``` from [here](https://www.fosslinux.com/43890/how-to-restart-kde-plasma-desktop-without-rebooting.htm) Also, restarting DE every time fn / multimedia stops working does not sound like a long-term solution 🙂 Thx for support and ping me here if you need more debugging / more details about my system. I spotted that in 100% cases this problem occurs is after the laptop sleep mode, but it might be not the first sleep after reboot… ---

On a hunch, please try this in the terminal and reboot. ```auto echo "blacklist cros_ec_lpcs" | sudo tee -a /etc/modprobe.d/no_cros_ec.conf ``` I don’t believe it’s related, but I’d like to rule it out as there are some issues that have affected function keys on 11th gen systems. ---
