Before I begin. I did read (https://discussion.fedoraproject.org/t/fractional-scaling-gnome-on-x-org-how-i-can-enable-it/73156/5) and the op couldn’t get it working.
So, I did enable fractional scaling on Wayland using the command gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"
, it showed up in the display setting and it works, at least on supported apps.
When I try to enbale scalling on the X11 session, with the command gsettings set org.gnome.mutter experimental-features "['x11-randr-fractional-scaling']"
the display options in the setting app only show 100% and 200% , not 125% or 150%?
Therefore how do I enable fractional scalling on X.Org session in Fedora 34?
