I finally had it this week having to use 3 keyboards/mice for my computers around my personal office. My friend, a while ago, told me about an open-source solution called synergy.
I installed it last night on two ubuntu machines and it was so easy and fast to install.
sudo apt-get install synergy quicksynergy
Then create a synergy.conf . Here’s mine:
sudo vi /etc/synergy.conf:
right = kelly
left = mary
screenSaverSync = false
# My KVM uses Scroll Lock to switch screens, so set the
# hotkey to lock the cursor to the screen to something else
keystroke(f12) = lockCursorToScreen(toggle)
synergys -f –config /etc/synergy.conf
And that’s it. It works awesome! Check it out if you have multi-monitors with different boxes.
