Thinkpad fn key - ubuntu 18.04
I have a thinkpad x250 which, for almost everything, worked flawlessly out of the box with ubuntu 18.04.
But fn key doesn't seem to behave, pressing it alone changes the keyboard backlight, it doesn't work in combination (fn+F1 or fn+SPACE for example), some work if fn is locked with ESC, and some others don't. acpi_listen recognize most of them, but gnome seems to ignore some that acpi recognize.
What I've researched seems to be either outdated, fragmentary, or both. What I need, more than a concrete solution, which will be nice, is a guiding light of how this actually works under ubuntu to fix the behavior.
EDIT: looking at showkey or evtest output, apparently pressing fn alone produces a few key events, (as KEY_WAKEUP) including space, which makes sense with keyboard backlight activation.
Using BIOS swap fn and control option make hotkeys work, but fn (now KEY_LEFTCTRL) still seems to add a few events apart of expected, at its own will, apparently in a too intelligent way to be keyboard malfunction. Still lost at this one.
