AV Access KD-E10 Linux support (fix monitor disconnect and device restart on 2x1 Dual-Monitor KVM Dock Switcher)
# Based on https://community.avaccess.com/t/kd-e10-34-monitor-with-3440x1440-goes-off-and-on-on-linux-xubuntu-24-04-only/446/3
# This solves the monitor disconnect and device restart that happened every ~25s on Pop!_OS 22.04 LTS
# when the USB Type-B to Type-A cable was connecting the desktop and the dock/switch, with the device 2 (desktop) being active.
# The original author reported the issue on Xubuntu 24.04
# The cause of the issue seems to be `brltty` taking over the UART interface on the KVM Switch/Dock, mistakenly detecting
# the CP210x (USB to UART bridge) controller present on the device as a Braille terminal.
# The following two lines stop the currently running `brltty` service and mask it so that it doesn't get activated again.
sudo systemctl mask brltty-udev.service
sudo systemctl stop brltty-udev.service
# More info: https://koen.vervloesem.eu/blog/how-to-stop-brltty-from-claiming-your-usb-uart-interface-on-linux/

This also appens on stock debian, zorinos, and many debian-based distro :O Thank you man
Edit : I also have this problem with keyboard, even if brltty service does not exist...
