Check your session type – wayland or X11

With both wayland and X11 in mainstream, its pretty easy to forget if you are running in Wayland or in X11. To check this here are the commands:

loginctl list-sessions
# The above command will show you all the sessions. Note the session number for your session

loginctl show-session <session number> -p Type

Sometime back I noticed that whenever I run my favourite command, viz.

journalctl -xn -f -l

it was taking more time than usual. So, I thought to dig more into it and finally found that the following command:

sudo journalctl --disk-usage

showed that journalctl was using some huge space in tune of about 4GB. So, the solution was simple, vaccum the journal entries and the command to do so is :

sudo journalctl --vacuum-size 90M

Checking journalctl size after that confirms the size is reduced and after that indeed the above journal command takes no time 🙂
