18. Trouble-Shooting
If you suspect that the problem is a hardware problem, see the Repair and Diagnose section. If it's the keyboard see Keyboards. If it responds incorrectly (if at all) to what you type. see Corrupted Terminal Interface. If the problem involves the serial port itself see the Serial-HOWTO.
Here is a list of possible problems:
- Is the Terminal OK ? Suspect the terminal is defective.
- Display Freezes (hung terminal)
- Displays Foreign/Weird Characters/Symbols
- Displays Escape Sequences
- Missing Text Either skips over some text or displays some text OK and hangs.
- All Keys Work Erratically; Must Hit a Key a Few Times
- If getty run from command line: Programs get stopped with message "Stopped"
- Getty Respawning Too Rapidly (console error message)
- Fails Just After Login
- Can't Login but login prompt is OK.
- Garbled Login Prompt
- No Login Prompt
There are two cases where the terminal goes bad. One is when it's been recently working OK and suddenly goes bad. This is discussed in the next sub-section. The other case is where things don't work right just after you install a terminal. For this case you may skip over the next section.
