Ubuntu – minimize a window from the command line

command linewindow-manager

I would like to be able to choose any already-open window and minimize it from the command line. Is this possible?

Best Answer

In Kubuntu 12.04 I use the following command to minimize the active window:

xdotool windowminimize $(xdotool getactivewindow)

I suspect you may replace the $(xdotool getactivewindow) with a string identifying any window that you need to minimize.

Ubuntu – How to restart X Window Server from command line

NOTE: This will forcefully quit all graphical programs, you'll lose any unsaved work, and you'll be logged out. Non-graphical programs will not be affected.

TL;DR: on systems with systemd (Ubuntu 15.04 and newer)

sudo systemctl restart display-manager

This will restart the appropriate display manager service (lightdm till 17.04, gdm3 after, sddm in Kubuntu, etc.). You can replace display-manager with lightdm, gdm3, sddm, etc. if needed, but this should be enough.

For other Ubuntu versions, first find which display manager your ubuntu is having with following command:

cat /etc/X11/default-display-manager

Than depending on what display manager, you can use one of the following commands:

Default Ubuntu (with LightDM)
```
sudo systemctl restart lightdm  
```
Gnome (with GDM)
```
sudo systemctl restart gdm
```
KDE (with KDM)
```
sudo systemctl restart kdm
```
Note: From 12.10 to 15.04, Kubuntu also uses LightDM.
For MDM (e.g. for Mint Cinnamon)
```
sudo systemctl restart mdm
```
