Configure Linux Mint 21


Login with "guru", password "guru" at the "MDM Login Manager" (MDM = Mint Display Manager).

You're greeted with a "Welcome screen". Take a look around and then remove the check "Show this dialog at startup".

Add taskbar

In this case, I have 2 monitors. Go to Menu -> Preferences -> Display

The left monitor must be the "primary". If necessary, switch monitor positions by dragging and click "Apply". If everything looks good, confirm this configuration.

Left monitor: right-click on the taskbar and choose "Add a new panel".

Red bars become visible on each side of both monitors.

Right monitor: click on the bottom red bar. A task bar is added and the red bars disappear.

Add applets

Right monitor: right-click and activate "Panel edit mode". Then choose "Applets".

Right monitor: navigate to "Grouped window list" and click on the + sign. Some icons become visible at the bottom right. Probably a bug, but is hard to see those icons. Close the "Applets" window.

Right monitor: Drag those icons all the way up to the left side of the screen (still on the right monitor!) and release the mouse.

Right monitor: right-click on the bottom taskbar and deactivate "Panel edit mode".

Configure update mirror

Go to "Menu -> Administration -> Update Manager".

Read the text and click "OK".

Let's use a local mirror for fast downloads. Click "Yes" in the blue bar and authenticate with the "guru" password.

Click in the field "Main (...)". Another window appears. Select the repository with the fastest speed. In this case, I choose "LiteServer" for lab purposes and click "Apply".

After changing the "repository mirror", the APT cache has to be updated. Click "OK".

Close the "Software sources" window and proceed with the updates. In this case, a new version of the "Update Manager" is available. Apply the update. Again, the password of "guru" is asked.

Install updates

A list of available updates is presented. Select "Install Updates". Confirm the (possible) message concerning additional changes. Again, the password of "guru" is asked.

Finally, all updates get downloaded and installed. Grab another coffee! Or click on "Details" to see what the system is doing ;-)

When the system is up-to-date, reboot the PC.

Login. Start the "Update manager" again and click "Refresh". Your system should be up-to-date. If not, repeat previous steps.

System reports

Go to "Menu -> Administration -> System Reports". Ignore the reports concerning the "language packs (1)" and "the system restore utility (2)".

No problems detected? Done!
