It got reported that it no longer works to just force Xft.dpi: 96. The checkbox checking does not enable the Apply button. I also noticed that it only allows to set certain predefined values, which I consider a regression. Some set the dpi to make it easier to read, which might just as well be 110dpi.
Still present in 5.12.90.
fix on phab
Git commit b2694cfc64de7e6a11fd5ba91f9bacb01b6ad9de by David Edmundson. Committed on 23/05/2018 at 09:40. Pushed by davidedmundson into branch 'Plasma/5.13'. Fix Font KCM force font DPI checkbox Summary: Fixes numerous issues: 1) the default behaviour had changed. It should disable force font DPI, not set it to 96 2) disabling didn't work, we'd set the value to 0, which would update the spinbox, which has a minimum which sets the value to 96 (we were warned of this with a binding loop error) 3) toggling the checkbox didn't enable the apply button New code fixes that and is more declarative too. Test Plan: Toggled, reset to defaults, restarted Reviewers: #plasma, progwolff, broulik Reviewed By: #plasma, progwolff, broulik Subscribers: broulik, plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D13051 M +1 -1 kcms/fonts/fonts.cpp M +7 -10 kcms/fonts/package/contents/ui/main.qml https://commits.kde.org/plasma-desktop/b2694cfc64de7e6a11fd5ba91f9bacb01b6ad9de
