CAPS LOCK led doesn't work with dumbkbd because dumbkbd option disables
the i8042 module write capability, so the i8042 can't write the led
status to the keyboard controller. Unfortunately this is a side effect
of dumbkbd option, but there can be others too. I digged a bit into
kernel source code a
Did you mean i8042.dumbkbd instead of i8042.direct?
To me it happens that i8042.direct causes no apparent side effects, and the
sporious events are triggered once after pressing CAPS LOCK or NUM LOCK;
i8042.dumbkbd instead causes the CAPS LOCK keyboard led not to blink (and this
is expected), bu
This is GREAT news! We have a hint to start with.
i8042.c linux kernel source code defines more module parameters. The module
parameter "direct" disables the scan code translation, but the module parameter
"dumbkbd" completely disables the write capability of the kernel module to the
i8042 cont
I just discovered that NumLock and CapsLock keys restore the spourious
