I'm seeing flakiness in X11 (KDE) with evdev enabled - a couple keys are
reporting multiple (wrong) events and some aren't emitting any events
(or they are, but they're NoSymbol):
- Down arrow: emits KeyPress for keycode 116 (Super_R), KeyRelease for
keycode 116, KeyRelease for keycode 104 (Down)
- Left arrow: emits KeyPress for keycode 113 (Alt_R), KeyPress for
keycode 100 (Left), KeyRelease for keycode 113, KeyRelease for keycode 100
- Volume up: emits KeyPress 123 (NoSymbol), KeyPress 176 (NoSymbol),
KeyRelease for same
- Volume down: emits KeyPress 122 (NoSymbol), KeyPress 174 (NoSymbol),
KeyRelease for same
- Volume mute toggle: emits KeyPress 121 (NoSymbol), KeyRelease 121
(NoSymbol), KeyRelease 140 (NoSymbol)
- Keypad end: emits KeyPress 115 (Super_L), KeyPress 103 (End),
KeyRelease for same
I'll attach the output of 'evdev -event keyboard' for everything but the
Keypad end key which I recently found.

Not sure what else to add. I have applied the patches from this email

Thanks in advance,

Hi Vladimir and Jan,
Thanks for the patches! I'm having some issues with 3 patches from this
thread:
-
https://reviews.freebsd.org/file/data/pqjvpuhwfgsu5nnamibg/PHID-FILE-uuyjx66blb344hre3nc2/D10207.vson.id27478.whitespaceignore-most.diff
- https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218625
- https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218627
These may or may not have anything to do with the patches...
1. For some reason Xorg keyboard driver isn't getting some key events,
or had shuffled them. When I first applied the patches, X thought my
<Down> arrow was <KP_Enter> and <KP_Enter> was something else. At some
point that behavior changed and <Down> worked, but <KP_Divide> emits
<KP_Multiply> and <KP_Multiply> doesn't emit anything. Rebooting didn't
change the new behavior, and I don't know what caused it to change.
Switching to a console, I get the expected characters/actions when
pressing these keys.
2. My Synaptics clickpad (and the pointer in general) freeze for several
seconds, although it hasn't done it lately. When a freeze occurs (in X
windows), other GUI processes don't seem to be affected. If I have
another pointer device attached (e.g. USB mouse), it also doesn't move
the pointer during the freeze.
Here's my config:
