I use Ubuntu over a Manhattan KVM switch (8-port HDMI) that worked perfectly with Ubuntu 18.04. I performed an update from 18.04 to 20.04 and my mouse and keyboard (connected over the KVM switch) stopped working.
I tried to reproduce the issue with another system and got the same: not-working keyboard and mouse.
lsusb
shows the KVM-switch as Logitech Unifying Receiver.
Do I need to load a specific kernel module?
Currently logitech-djreceiver
is loaded according the dmesg
output. I did attach another mouse and keyboard. These make use of hid-generic and work.
Did anyone face a similar situation? Are there any ideas for solving the issue?
