The previous recipe was to use qt4-config, which is no longer working as you can't select a qt4 related theme.

Any solution available? It's very small font on 4k monitor.

A bit late to the party, but the only thing I found was zooming.

It affects the sidebar but at least the chats become more readible.

You can try the Zoom in shortcut Ctrl+Shift+= (I found it in View, where you can click directly).

Use Ctrl+0 (what they called Actual size) to reset and Ctrl+- to minize the size.


Don't know if it will work on Fedora, but on my Ubuntu I could achieve it by simply editing skypeforlinux bin and adding --force-device-scale-factor attribute:

sudo nano /usr/bin/skypeforlinux


nohup "$SKYPE_PATH" --executed-from="$(pwd)" --pid=$$ "$@" > "$SKYPE_LOGS/skype-startup.log" 2>&1 &


nohup "$SKYPE_PATH" --force-device-scale-factor=1.3 --executed-from="$(pwd)" --pid=$$ "$@" > "$SKYPE_LOGS/skype-startup.log" 2>&1 &
