Fractional scaling resets on sleep in Linux
On the github page for the HiDPI Daemon it says "This program is for managing HiDPI and LoDPI monitors on X. This program is installed by default in Pop!_OS and Ubuntu (if installed by System76 and can be added with this article)."

Exploring System76's New Rust Based Desktop Environment
> 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:

- 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.
If the next version of COSMIC supports fractional scaling on Wayland as well as this daemon does on X11, this alone would make the entire project will be worth it. GNOME Shell still hides fine-grained fractional scaling behind an experimental flag for both X11 and Wayland, with X11 needing a patch for Mutter.

The Razer Blade Stealth Late 2020 and Pop!_OS Are a Perfect Match
Hi u/Borisminator! I'm a razer+Pop!_OS user too. Mine is the early2020. A couple of questions: - Are you having the scratching noise when the fans start up? (https://www.reddit.com/r/razer/comments/jvh90m/razer_blade_2020_scratching_noise_when_fans_start/ - my video in the comments) - I'm having lots of errors from hidpi-daemon when I set hybrid mode ( https://github.com/pop-os/hidpi-daemon/issues/34 and https://github.com/pop-os/hidpi-daemon/issues/38 )

The Serval WS from System76: A Powerful Linux Workstation Running PopOS
The following Linux distributions support different scaling factors on different displays by default: Pop!_OS, Ubuntu, Linux Mint, and Manjaro.
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...
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...
Linux Mint implemented fractional display scaling, with different settings for each display, in Cinnamon 4.6:
https://blog.linuxmint.com/?p=3858
Arch Linux users can also use Cinnamon for the same features.
If you are using 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 more stable than X11 in other areas.

Show HN: Dropflow, a CSS layout engine for node or <canvas>
> wondering if css and svg could be used as abstraction over graphics and UI libraries
There's another project called Sciter that uses CSS to target native graphics libraries: https://sciter.com
> I wonder how hard it was to implement css. I've heard it can be pretty complex.
It was hard, but the biggest barrier is the obscurity of the knowledge.
Text layout is the hardest, because working with glyphs and iterating them in reverse for RTL is brain-breaking. And line wrapping gets really complicated. It's also the most obscure because nobody has written down everything you need to know in one place. After I finished block layout early on, I had to stop for a couple of years (only working a few hours a week though) and learn all of the ins, outs, dos, and don'ts around shaping and itemizing text. A lot of that I learned by reading Pango's [1] source code, and a lot I pieced together from Google searches.
But other than that, the W3C specifications cover almost everything. The CSS2 standard [2] is one of the most beautiful things I've ever read. It's internally consistent, concise, and obviously the result of years of deliberation, trial and error. (CSS3 is great, but CSS2 is the bedrock for everything).

So you want to write a GUI framework (2021)
These bullet points are exactly what I did in Sciter (https://sciter.com)
- Windowing
-- Tabs
-- Menus
-- Painting
-- Animation
-- Text
-The compositor
-Handling input
-- Pointer input
-- Keyboard input
- Accessibility
- Internationalization and localization
- Cross-platform APIs
- The web view
- Native look and feel
On top of that DOM and CSS implementations to achieve declarative UI. And JS as a languuage behind UI - declarative in some sense way of defining UI behavior.

Servo, the parallel browser engine written in Rust
I'm not sure if it can support all the libraries but yes it can be used to make desktop apps. Theres also Sciter.
