So I've got a similar issue with HP 15s-fq2032ua (48V94EA). Keyboard activated with a huge delay (up to ~160s). Pressing some KB keys probably helps to activate it faster.
Luckily I've found a workaround and didn't notice any side effect from it yet
It's a GRUB/boot option
sudo nano /etc/default/grub
add option chaging
Solution for Gnome Wayland:
You can unset the keybindings for virtual terminal switching by setting these dconf properties:
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-7 "['']"
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-8 "['']"
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-...
I've had the same issue on my Ubuntu 20.04. I have toggled off all GNOME Shell Extensions and it works fine now, so some extension might be the cause for you too.
You might want to test each extension to find which one is overriding your keys. In my case, the Clipboard Indicator holds the Ctrl+F9 to Ctrl+F12.
Other places to look at are /org/gnome/desktop/wm/...
To disable the Super key, you can go into Gnome Tweaks (if this is not installed, sudo apt install gnome-tweaks.
Then, go into Keyboard and Mouse,
You can either change it to Right Super, or explore the advanced settings and try to disable it there.
Issue following command in the terminal or in the Alt+F2 run dialog to disable the Super key when pressed alone:
gsettings set org.gnome.mutter overlay-key ''
Following command restores the default behavior:
gsettings reset org.gnome.mutter overlay-key
The default desktop environment (Gnome) for Ubuntu does not support keyboard navigation on the Desktop. You can choose to install a different desktop environment, like Cinnamon. This video shows how to install the Cinnamon desktop environment.
The most probable explanation is that you are inadvertently hitting the Next Input Source keyboard shortcut. The default for this is Super + Space, ie. pressing the Windows key and the spacebar at the same time, which is pretty easy to hit by accident.
See https://help.ubuntu.com/stable/ubuntu-help/keyboard-layouts.html.en for details.

Well, this solution works for me. Just with few mods added (and 21.04 Ubuntu version considered).
In order to define the wakeup command from a device, you need to take note about that:
The previous MB WakeUp config check state (Ignored in your case, it's looks like autodetected).

The lag disappears when the second keyboard is separated into second master using 'xinput create-master Second' and then attaching the second keyboard to it using 'xinput reattach '.
That however creates a second mouse pointer too (which is blinking annoyingly on my screen) and each of the keyboards has their own focus. One keyboard can type into one window ...
Linux uses XKB keyboard layouts, and most layouts (including Swedish and Finnish) defines AltGr by default as the key to access 3rd level symbols.
On Ubuntu you can use Tweaks to pick some other key. But AFAIK it's not possible to choose a key combination such as LeftCtrl+LeftAlt for that purpose.
Linux is not Windows, and when switching from one to the ...

Just want to thank and confirm this has helped me.
TLDR: I use Dell Latitude E6420 with Ubuntu 21.10, the package name used is
sudo apt install nvidia-driver-390
First I tried driver version 495 (package name: nvidia-driver-495), it rebooted and go to to safe graphics - 640x480 resolution.
Then did "grep -i nvidia /var/log/dmesg"...
I tried the tools suggested in the other answer, and found the mentioned key combinations are not detected, even though they are detected independently.
I tried pressing the keys a little bit harder, and now the key combinations are working.
So, I think there was some contact issue in the keyboard because of dust.
Try going to your Oracle VM VirtualBox manager and then File->Preferences->Input then choose the Virtual Machine tab. You may find that the "Host Key Combination" is set to Ctrl or Right-Ctrl. Click the little orange/white icon to set this to None. This fixed the problem for me.

To assess whether the keyboard is failing, you could use any application to monitor key presses.
See options here, here, here:
You can perform further evaluations by:
Booting from a Live USB and/or Windows. If the problem stems from your Ubuntu configuration, these should work.
Using another keyboard in your Ubuntu.

It seems like Ubuntu lost the UK language support during the upgrade, reverting instead to US English. This silently removed support for UK keyboard layouts. I don't know how this broke the modifier keys, but it did.

The keyboard and trackpad will always appear as "unavailable" on an Apple device as the rest of the system really doesn't like it when these things disappear from the USB bus.

Here is a workaround for this issue.
It's not pretty, but it works reliable enough for me.
The .xbindkeysrc configuration allows to specify arbitrary commands.
By using temporary files that are stored in the home directory of the user the current state of the button press can be saved and retrieved when the second press occurs.
With that the second press is ...
I am using the .bashrc file in the same directory to add commands that should be executed on terminal open:

Turns out, you can remap keys in the Linux kernel.
Determine the scan code of the key you want to remap to be some other key. This will be a hexadecimal number and you can see it in sudo showkey -s. Be careful, the program will emit both the codes for the keypress event and the release. Let's say I want to change the behavior of the 0xe021 key (Calculator ...

In my Ubuntu 20.04.3 LTS the Document Viewer alias evince can be closed

XFCE4 on Ubuntu Studio has that feature under "Accessibility" settings:
You then just need to add a shortcut to xfce4-find-cursor in the keyboard shortcuts. You can choose any key you like, including left or right Ctrl. However, it will also activate on any other Ctrl+... combinations then of course.
