# Black screen and LightDM doesn't unlock
|
||
|
|
|
||
|
|
Add this to your /etc/lightdm/lightdm.conf file:
|
||
|
|
|
||
|
|
```
|
||
|
|
[LightDM]
|
||
|
|
logind-check-graphical=true
|
||
|
|
```

# Edit previous commands
|
||
|
|
|
||
|
|
`fc` is a shell builtin to list and edit previous commands in an editor.
|
||
|
|
In addition to editing a single line (which you can also do with `C-x C-e`), it also allows you to edit and run several lines at the same time.
|
||
|
|
You use it like this:
|
||
|
|
|
||
|
|
List previous commands
|
||
|
|
```
|
||
|
|
$ fc -l
|
||
|
|
10259 nvim deploy.sh
|
||
|
|
10260* cd ..
|
||
|
|
10261* nvim content/cheatsheet/linux.md
|
||
|
|
10262 cd
|
||
|
|
```
|
||
|
|
|
||
|
|
List commands with date (in zsh)
|
||
|
|
|
||
|
|
```
|
||
|
|
$ fc -ld
|
||
|
|
10260* 19:38 cd ..
|
||
|
|
10261* 19:38 nvim content/cheatsheet/linux.md
|
||
|
|
10262 19:40 cd
|
||
|
|
10263 19:40 fc -l
|
||
|
|
```
|
||
|
|
|
||
|
|
You can add the date too:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ fc -fld
|
||
|
|
10262 1/10/2019 19:40 cd
|
||
|
|
10263 1/10/2019 19:40 fc -l
|
||
|
|
10264 1/10/2019 19:40 fc -ld
|
||
|
|
```
|
||
|
|
|
||
|
|
You can edit a range of commands
|
||
|
|
|
||
|
|
```
|
||
|
|
$ fc 10262 10264
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
The range can be relative to the current position, so the previous command is equivalent to:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ fc -3 -1
|
||
|
|
```
|
||
|
|
|
||
|
|
If you save and exit, all commands are executed as a script, and it will be added to your history.
