I just got a Level1Techs KVM from another user but have been having some issues with the keyboard hotkeys. I have a GMMK Pro with QMK installed on it and the hotkeys (ctrl ctrl 1/2) works fine when I just plug it in, but after it’s been plugged in for a while the hotkeys for some reason stop working. Keyboard works fine on Windows/MacOS, its just the hotkeys that stop working. I have to restart the KVM (unplug/plug back in) to get the hotkeys to work again, simply unplugging and replugging the keyboard does not fix it.
As a side note, when using the KVM with my macbook it generally works fine (thunderbolt dock → usb-c → displayport), but sometimes it will be working fine and then my monitor will display “noise” (white/black pattern you get on analog TV’s with no signal) and then go to black with no signal. Restarting the KVM seemed to fix this as well.
This is a symptom of transient EM. Restarting the kvm fixes it because it forces a handshake. It’ll do the same if you “reboot” the USBc cable by unplugging from both ends and replugging. If you use a moshi usbc cable it’ll probably clear it up or possibly club3d dp cables which are higher end than best buy
Gotcha, thanks! Will grab a new cable for that. Does the normal 12ft guidance apply with a thunderbolt hub? (should the cable going from macbook → thunderbolt hub be included in that length).
Also, why would nkey rollover make the keyboard hotkeys stop working after a while? Wouldn’t that be either a working/not-working situation, instead of a works for the first hour then stops working?
