Kubuntu 18.04 Setup Notes


Redshift helps with eyestrain by decreasing the amount of blue colors/light coming from the monitor (I think). redshift-gtk enables a taskbar icon for the program with rudimentary ability to see the current configuration, enable/disable, and autostart.

sudo apt install -y redshift redshift-gtk geoclue-2.0

Kontact / KMail / PIM


Show Your Own Replies in Threads in the Inbox

In order for your replies to be included in threads in the inbox, they must not be moved to the 'Sent' folder. To accomplish this enable the Keep replies in this folder option that is found in the right click context menu launched by right clicking the 'Inbox' label'. If you also want to be able to see your replies in the 'Sent' folder as well you can create a filter / rule to copy replies there; see the following SO post:

Gripes about Small Font Size in Firefox

The font-size in firefox seems pretty tiny; something seems wonky. There are lots of cases of people griping about it; ex:

Upping the system-wide DPI helps but creates issues in most other applications, so it's a non-starter. Constantly zooming in firefox is annoying and not really a solution either. Firefox's own font settings seem to only affect the menu bar, tab bar, etc. as opposed to the actual webpage text. At a loss on this one so far.

Task Switch / Alt-Tab Behavior

In Settings → Window Management → Task Switcher, change the visualization to 'Thumbnails'.

Misc. Additional Programs

sudo apt install git
