-====== terminator vs ubuntu 18.10 - broadcast issue ======+====== terminator vs ubuntu 18/20 - broadcast issue ======
 terminator is a very good graphical terminal emulator for linux. Its main advantage is that it allows to split the screen into several terminal windows and add tabs with additional split screens. On top of that, on can broadcast from one terminal to others.  terminator is a very good graphical terminal emulator for linux.

 ===== Problem ===== ===== Problem =====
 There is an issue with broadcasting in ubuntu 18.10 with its standard desktop environment. every key that is pressed in the sending terminal is written twice in the receiving ones.  There is an issue with broadcasting in ubuntu 18.10 with its standard desktop environment. every key that is pressed in the sending terminal is written twice in the receiving ones. 
 +===== Reason =====
 +somehow terminator seems to have issues when ibus is involved
 ===== Solution ===== ===== Solution =====
 +we need to make sure that terminator does not use ibus. this is done differently in ubuntu 18 and ubuntu 20: 
 +
 +==== ubuntu 18 (tested with 18.10 but should also work with 18.04) ====
 as pointed out in [[https://bugs.launchpad.net/terminator/+bug/1318542/comments/26|a comment on a but report]] related to this issue, one can  unset the ''GTK_IM_MODULE'' environment variable prior to starting terminator which will work around the problem.  as pointed out in [[https://bugs.launchpad.net/terminator/+bug/1318542/comments/26|a comment on a but report]] related to this issue, one can  unset the ''GTK_IM_MODULE'' environment variable prior to starting terminator which will work around the problem. 
  
 +==== ubuntu 20.04 ====
 +here we need to unset ''DBUS_SESSION_BUS_ADDRESS'' for terminator to work correctly
 +
 +==== the script: ====
 the problem with the proposed alias is, that this only works if you start terminator through a bash shell. however, if you click the launcher icon in gnome it is ignored. the problem with the proposed alias is, that this only works if you start terminator through a bash shell. however, if you click the launcher icon in gnome it is ignored.

-  chmod 755 /usr/local/bin/terminator''+  chmod 755 /usr/local/bin/terminator
  
 the reason why this is saved to ''/usr/local/bin'' is, that this directory is listed in the ''PATH'' variable before ''/usr/bin'' is listed where the actual terminator binary resides. hence, when someone starts terminator wihtout providing a full path, our wrapper script will be launched first.  the reason why this is saved to ''/usr/local/bin'' is, that this directory is listed in the ''PATH'' variable before ''/usr/bin'' is listed where the actual terminator binary resides. hence, when someone starts terminator wihtout providing a full path, our wrapper script will be launched first.

 we could have also renamed the actual binary and then saved the wrapper in its place, or we could have modified the launcher file, but both of these solutions will probably brake on each update of terminator, while our little hack, although not pretty, will survive updates as well.  we could have also renamed the actual binary and then saved the wrapper in its place, or we could have modified the launcher file, but both of these solutions will probably brake on each update of terminator, while our little hack, although not pretty, will survive updates as well.

 +===== Ohter problems =====
 +==== split-screen shortcut ctrl+shift+e not working ====
 +if terminator works with ibus active, you can experience a strange behaviour when using the ctrl+shift+e shortcut to split screens: you will get an underlined "__e__" and the terminal behaves strange until you press escape. this is because this same shurtcut is used by ibus to write emojis. you can change the ibus shurtcut by running 
 +  ibus-setup
 +then go to the emoji tab and either change or remove the shortcut
