To be more clear, it ASKS if you want to restart them. If you don't, |
| 29 |
you can hit "n" to skip restarting it. For example, if you are in |
| 30 |
Konsole running the command and it wants to restart the GUI, which would |
| 31 |
kill your Konsole session and anything else not saved, then you can say |
| 32 |
no and move on. Later on, you can logout and restart or whatever. |
| 33 |
|
| 34 |
Main point tho, it only asks you if you want to. It doesn't blindly do |
| 35 |
it. |
