The following Linux distributions support different scaling factors on different displays by default: Pop!_OS, Ubuntu (and GNOME-based derivatives), Linux Mint. Arch Linux, Manjaro, and all distributions using GNOME + Wayland can also enable mixed scaling with a quick setting change.
Pop!_OS (developed by System76) created its own HiDPI daemon to handle HiDPI and LoDPI displays on X11 at the same time:
It is preinstalled on all System76 computers and enabled by default.
Ubuntu's fork of the Mutter display manager (used by its fork of GNOME) includes a patch to handle different display resolutions for HiDPI and LoDPI displays on X11:
Arch Linux and Manjaro users can also choose Cinnamon as the desktop environment for the same features.
If you are using a GNOME on X11 on Manjaro, you can install the mutter-x11-scaling package to replace Mutter with a version that includes Ubuntu's changes:
Finally, if you are using GNOME on Wayland, mixed scaling is already supported. To enable fractional scaling, activate the "scale-monitor-framebuffer" setting:
On Wayland, scaled applications that do not use GTK 3+ or Qt 5+ may appear blurry. This affects all Electron applications. X11 does not have the same issue, but Wayland is generally smoother and more stable than X11.

Ubuntu and all of its GNOME-based derivatives include this patch, unless it is specifically excluded by the maintainers.
Linux Mint implemented fractional display scaling, with different settings for each display, in Cinnamon 4.6:
