+## Black screen and LightDM doesn't unlock
+
+Add this to your /etc/lightdm/lightdm.conf file:
+
+```cfg
+[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
+
+```shell
+$ fc -l
+10259  nvim deploy.sh
+10260* cd ..
+10261* nvim content/cheatsheet/linux.md
+10262  cd
+```
+
+List commands with date (in zsh)
+
+```shell
+$ 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:
+
+```shell
+$ 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
+
+```shell
+$ fc 10262 10264
+```
+
+
+The range can be relative to the current position, so the previous command is equivalent to:
+
+```shell
+$ fc -3 -1
+```
+
+If you save and exit, all commands are executed as a script, and it will be added to your history.

+## Prevent logoff from killing tmux sessions
+
+Lately I've noticed that logging out of i3, intentionally or when i3 fails, would also kill any tmux or emacs sessions.
+This is extremely annoying.
+
+This is caused by a new default in logind (systemd's login) to kill user process on logoff.
+You can revert this setting in your logind.conf (`/etc/systemd/logind.conf`):
+
+```cfg
+KillUserProcesses=no
+```
+
+Or only for a specific process (e.g., tmux):
+
+```shell
+systemd-run --scope --user tmux
+```
+

+
+
+## Upload a temporary file 
+
+Sometimes you just need to copy/paste a file from a server, and copying from the terminal can be a hassle.
+These two services are command-line "pastebins" just one curl away:
+
+```shell
+<command> | curl -F 'sprunge=<-' http://sprunge.us
+# OR
+
+<command> 2>&1 | curl -F 'f:1=<-' ix.io
+
+# OR
+
+<command> | curl -F"file=@-" https://ttm.sh
+```
+
+
+# Install Fortinet SSLVPN support for NetworkManager
+
+UPM (Universidad Politécnica de Madrid) uses a propriatary VPN solution.
+The instructions for GNU/Linux on their website involve downloading a specific client (`.tar.gz`) and manually running it.
+That works, but it is kind of a hassle.
+A much more convenient alternative is installing this NetworkManager plugin:
+
+```shell
+pacman -Sy networkmanager-fortisslvpn 
+# Or apt get install networkmanager-fortisslvpn 
+```
+
+Now you can simply add a new VPN connection in NetworkManager and manage it as you would any other connection.
