A terminal emulator, terminal application, term, or tty emulates a video terminal within another display architecture (usually X). A terminal emulator will generally start the default shell that is defined as the login shell for given user. On Gentoo the default shell is bash.

If an X environment has not been set up in Gentoo, the system will boot to the first tty interface. Under most circumstances it is possible to access different terminal interfaces by pressing the Alt+F1 through Alt+F6 keys on the keyboard. The super key (often the "windows key" on many keyboards) will also toggle between terminals.

If an X environment has been set up, there are more than a few terminal emulator options available for the user to choose from - see next section. From an X11 session, the Linux virtual terminals can be accessed with Ctrl+Alt+F1 through Ctrl+Alt+F6 key combinations. If the X11 session was started from a session manager, it is often started on tty7. Return to it by pressing Ctrl+Alt+F7, otherwise return to the graphical session by going back to the virtual terminal on which it was started.

Troubleshooting

Display garbled after binary output

Generally corrupted or garbled output is not caused by the terminal emulator itself, but rather the programming running within the emulator. Often when binary output is displayed into the terminal, the program running inside the terminal will need to refresh the emulator in order for output to be corrected. Refresh is accomplished differently depending on the program.

bash

On occasion the text in the terminal emulator will become garbled. This generally happens if binary output is displayed to standard out (stdout). This can easily be fixed by typing the reset command.

When using bash, the shell can be cleared and redrawn by pressing ctrl+l (lower case L).

See the Bash article for more Bash specific features and fixes.
