Keycode or key combinations don’t match

Product: Synergy (all versions)
Operating system: Linux

If your client and server computer does not have the same keycode or key combination, you may need to use a temporary workaround to resolve this issue.

For example, let’s say your key code for the Server (Linux) computer is ISO_Level3_Shift while your Client key code (Windows) is Alt_R.

The workaround is to redirect the key code at the OS level. For example, if you do not use your Right Ctrl key much, you can map it to a new key code such as Alt+R. This way, you can use Ctrl+R if you need to make Alt+R work on your client computer.

To configure this in your Linux Server:

1. Open the terminal

2. xmodmap -pke > "$HOME/.Xmodmap"

3. nano "$HOME/.Xmodmap

   1. And add the following:

   2.  keycode 105 = Alt_R Meta_R Alt_R Meta_R

4. crontab -e

5. And add the following:

   1. @reboot sleep 30 && DISPLAY=:0 xmodmap ~/.Xmodmap
