> System76 with Pop_OS! has an opportunity to tackle topics head on like "we can make fractional scaling work somewhat decently across all apps" (IIUC currently requires shipping a forked XWayland, unfortunately) I'm excited to see System76's implementation of fractional scaling in this new desktop environment. Since they have actually sold laptops with 1080p and sometimes 4K displays, they have a real incentive to get this feature working smoothly on Wayland. System76 previously developed a HiDPI daemon for X11 to be used with GNOME Shell: - Blog post: https://blog.system76.com/post/174414833678/all-about-the-hi... - Help page: https://support.system76.com/articles/hidpi-multi-monitor/ - Source: https://github.com/pop-os/hidpi-daemon It handles multiple scaling factors, including fractional ones, flawlessly across displays.

ersion of COSMIC supports fractional scaling on Wayland as well as this daemon does on X11, this alone would make the entire project worthwhile. GNOME Shell still hides fine-grained fractional scaling behind an experimental flag for both X11 and Wayland,[1] with X11 needing a patch for Mutter.[2] [1] https://www.linuxuprising.com/2019/04/how-to-enable-hidpi-fr...

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: https://github.com/pop-os/hidpi-daemon https://blog.system76.com/post/174414833678/all-about-the-hi... 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: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/182085... Ubuntu and all of its GNOME-based derivati

ves 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: https://blog.linuxmint.com/?p=3858 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: https://gitlab.manjaro.org/packages/extra/mutter-x11-scaling... https://github.com/puxplaying/mutter-x11-scaling Finally, if you are using GNOME on Wayland, mixed scaling is already supported. To enable fractional scaling, activate the "scale-monitor-framebuffer" setting: https://wiki.archlinux.org/index.php/HiDPI#GNOME 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.
