This also affects or maybe affected me. I think the problem appears because the x server does not set the right dpi value - and for some reason the text-scale factor keeps to be reseted from time to time, maybe because of an update.
I manually set the correct dpi value of my screen (122dpi) in /etc/lightdm/lightdm.conf with adding this line: xserver-command=X -dpi 122 and restartet the x-server. Xorg.0.log now says: [ 3033.310] (++) intel(0): DPI set to (122, 122) <- this was (96, 96) before The Text-scale factor has been set to a usable value after that. Maybe some of you can try this as well (with your individual dpi settings for your monitor) to see if this really fixes the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310316 Title: Text scaling factor changing unexpectedly To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1310316/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
