You can use these commands and rules to search for exploitation attempts against log4j RCE vulnerability CVE-2021-44228
This command searches for exploitation attempts in uncompressed files in folder /var/log and all sub folders
sudo egrep -I -i -r '\$(\{|%7B)jndi:(ldap[s]?|rmi|dns|nis|iiop|corba|nds|http):/[^\n]+' /var/log
Hence, if you are interested in existing applications to "just work" without the need for adjustments, then you may be better off avoiding Wayland.
Wayland solves no issues I have but breaks almost everything I need. Even the most basic, most simple things (like xkill) - in this case with no obvious replacement. And usually it stays broken, because the Wayland folks mostly seem to care about Automotive, Gnome, maybe KDE - and alienating everyone else (e.g., people using just an X11 window manager or something like GNUstep) in the process.
Update 06/2025: X11 is alive and well, despite what Red Hat wants you to believe. https://github.com/X11Libre/xserver revitalizes the Xorg X11 server as a community project under new leadership.

K780 doesn't have a hard switch to lock the function keys. Logitech provides a utility to do this on Windows and iOS but not on Linux. You need to manually remap the keys.
Below works for Arch Linux, other systemd based distros should be about the same.
There's a problem with the F1-F3 keys as they're hardware specific and don't emit an event if pressed on their own and therefore can't be remapped. I might be wrong as I haven't spend any time on researching that.
