KDE 20.1rc2 4K display issues in 96dpi (3840 x 2160)

[belive]

Hi,

I'm hdmi connecting a laptop in 4K.
Eventhough I set the scaling to 200%, notice:
1/ Desktop toolbar stays tiny
2/ mouse pointer issues:
mouse pointer size set to 48
according to the zone it the mouse pointer is tiny or as it ought to be,
for instance on the title area of the window it has normal size, while within the window it shrinks as tiny

Nobody is testing in 4K ?

The instructions for Gnome, KDE/Plasma and XFCE assume an up to date environment installed from the official ISOs. For all the other Desktop Environments installation instructions are inc…

hidpify.sh

So I worked on this on a whim in a random thread some weeks back. I revisited it recently and cleaned it up a little. Its a little script that just automates what I would do for HiDPI config in KDE Plasma. All you really need to use it is which DPI you would like. PS It is largely intended for those who have not already made modifications to files such as /etc/environment or /etc/sddm.conf and so on. (though the script could give clues for the curious as to which files and options can be…
