Any advice as to how to debug this:
My K800 USB Wireless Keyboard's repeat rate intermittently stops working. It will start behaving erratically and when holding a key down it will either not repeat at all, or only repeat 3-4 times.
This occurs from any X11 (using xmonad), including konsole or gnome-terminal, etc. If i switch to a pseudo/virtual terminal ( C-Alt-F2 etc. ) , then the repeat rate is fine.
I have tried
xset r rate 350 30 and it doesn't work.
I have left it overnight and come back the next day to find that, magically, it all of a sudden works correctly.
Then randomly, at some point in the future, it will start again. And randomly it will stop later on.
I don't even know how to start to investigate this problem. I suspected maybe it is udev related? I tried something like this, as a gamble:
sudo rm -rf /dev/usb/* sudo rm -rf /dev/bus/usb/* sudo udevadm trigger
and it didn't help.
Also - when selecting text with the mouse in konsole ( but not firefox ),
the same stutter/stop occurs when the problem is happening. I can select maybe 1 or 2 lines and then it stops selecting ( despite still having the mouse button pressed down )
