--- Comment #6 from Jerry Williams <williams.jerry...@gmail.com> --- I can reproduce this with a new user. I only have Arch systems (x86-64 Arch and PineBook's ARM Manjaro) to test this on. By default, they do not ship any config file linked (10-hinting-{full,medium,none,slight}.conf). That's how I ran into this to begin with. Manually configuring EITHER the local or global fontconfig files reliably allows me to change the setting afterwards in the GUI. If NEITHER the local nor global fontconfig files set hintstyle, changes to the Hinting setting in the GUI are reliably not saved. I've included the local fontconfig file generated by System Settings after step 6 (before.fonts.conf) and after step 11 (after.fonts.conf). Steps: 1. Delete the link /etc/fonts/conf.d/10-hinting-none.conf which is the only global setting that sets hintstyle 2. Create a new administrator user via System Settings -> Users -> Add New User 3. Log out and log into the new user 4. Observe that ~/.config/fontconfig/fonts.conf file does NOT exist 5. Observe that the hint style is "Slight" in System Settings -> Fonts 6. Change the hint style to "Full" 7. Close and reopen System Settings 8. Observe the hint style is still "Slight" 9. Re-link the file `ln -s /etc/fonts/conf.avail/10-hinting-none.conf /etc/fonts/conf.d/` 10. Observe that the hint style is "None" in System Settings -> Fonts 11. Change the hint style to "Full" in System Settings -> Fonts 12. Close and reopen System Settings 13. Observe the hint style is now "Full" -- You are receiving this mail because: You are watching all bug changes.
