Cannot adjust font size in KMail

Post by phil_n » Tue Jun 19, 2018 6:06 am

I have installed KMail on LM 18.3, Cinnamon 3.6.6.

Adjusting fonts in the e-mail text works and also in the folders list.

My problem is that I can not adjust the font size in the message list pane. Nor can I adjust the font size in the menu bar.

Has anyone experienced the same problem and have a solution?

The issue here is that kmail is a KDE app, and KDE is built with Qt libraries, unlike Cinnamon which uses GTK. So you get issues having consistent theming and fonts. I use Mint KDE on my laptop but it's less of an issue using Qt apps in KDE than vice versa. I've always used mostly GTK apps in KDE and the theming is often different but it's not an issue for me if it works.

I don't know of any simple ways to make them consistent, and I'm not sure if it's worth the effort if everything is functional.
Here's the best guide I can find, but it's for Arch Linux, which is NOT ubuntu based ... the Arch wikis are an excellent resource but need more interpretation than most Linux beginners can muster ... don't go blindly copying and pasting ...

Hi phil_n,

For most KDE applications to run well on Linux Mint "Cinnamon", "Mate", or "Xfce" editions, you only need to install "kde-runtime". But, for some other integrated KDE applications like the excellent "Kmail" or "Kalarm", you would need to install "kde-runtime", "kdepim", "Kleopatra", "kio-extras", from the "Synaptic Package Manager SPM", and restart and see if that helps.

You can use the console terminal command below to install these at one time.

Code: Select all

sudo apt install kde-runtime kdepim  kleopatra kio-extras
You can customize almost anything KDE related, if you know how. For Kmail, see screenshots below.
1.) If you click Settings -> Configure Kmail -> Appearance (on left), Font tab, check customization, choose what to customize apply to like "Message List", select font characteristics, apply, okay. In my example I chose the Arial Bold font size 9.

2.) If you want to get even more fancy, color your emails by whatever you want subject, sender, receiver, content, etc... In the example screenshots, I want my email notifications regarding my posts and replies from Linux Mint to be highlighted in color from the Linux Mint forums (admin@linumint.com),

-- Create Email Tag: in the Settings -> Configure Kmail -> Appearance -> Tag tab, create a tag "Linux Mint" (apply/ok), OR right click an email message, select "Mark Message" Add Tag

-- Create Email Filter: click Settings and "Configure Filters" to create a new filter using that Tag, OR right click an email message, select "Create Filter" and follow prompts and use the tag you just created. It may take a little practice, but once you have done it, it becomes easier.

This is great for highlighting important emails from business, family, friends, etc...

sudo add-apt-repository ppa:kubuntu-ppa/backports

Code: Select all

sudo apt-get update
