After using Linux Mint with Cinnamon for a long time I am now back with Ubuntu with GNOME (reluctantly, I may add).
One thing I have noticed is there does not seem to be an option in the settings to change your preferred terminal emulator.
I’ve been using the excellent terminal emulator Terminator for a long time. Terminator sports (among other things) split screen hand “cluster support” (grouping of screens, making it possible to type the same thing in all terminals).
In previous versions of Ubuntu (Terminator versions prior to 0.14) Terminator would pick all settings from GNOME Terminal, including character encoding (ISO-8859-15 in my case). Apparently this is no longer the case in Ubuntu 10.04, which has Terminator 0.14.
To use another encoding than UTF-8, add the following to ~/.config/terminator/config:
Substitute ISO-8859-15 with whatever encoding you want.
Some other nice configuration options
scrollback_lines = 10000 # Scroll back size
focus = sloppy # sloppy focus, ie. the focus follows the mouse when moving the pointer to another split-screen
for more options, run man terminator_config.
