How can I set a custom value for font DPI in KDE?
The only options available in KDE are 96 and 120 DPI values. My Screen resolution is 1920*1080, so I would like to keep the DPI at a value higher than 120.
I know how to do this in gnome.
Could any one tell how to set custom DPI values in KDE?
A GUI method is preferred
Found a way for KDE 4 (up to Ubuntu 14.10). For modern KDE 5 see other answer.
Go to System Settings → Application and System Notifications → Manage Notifications.
Select Screen Saver as the Event Source
Locate and select the Screen Locked
add this command to the event:
xset dpms force off
It will turn off all displays every time it gets locked.
To get current DPI resolution use
xdpyinfo | grep -B2 resolution
To update DPI resolution say to 142 dpi use
xrandr --dpi 142

Configuration can be done per-user through ~/.fonts.conf, and globally with /etc/fonts/local.conf. The settings in the per-user configuration have precedence over the global configuration. Both these files use the same syntax.
Just scroll down and change the DPI value in the conf file. You may have to restart x or logout/login to KDE to get the change to apply.
This applies to most DEs, I don't know of any GUI method to do it other than what you have tried already.
