#Tech post! #Today I finally found time to remove #Fedora from my #Linux laptop. I had intended to replace it with #MXLinux - in fact for a couple of hours I did - but in the end I had so many problems customising #KDE #Plasma that I actually stopped and had a rethink.

I had always liked Plasma for its customisability, but wrestling with panel configuration seems to be getting harder - or I'm getting older - and I just couldn't get the desktop how I wanted it. After 2 hours I realised life was too short for such nonsense.

I needed a polished distro with fractional scaling on #HiDPI displays, and after some research to get me up to date, I plumped for #Pop_OS with its #COSMIC desktop.

Pop_OS is great - it has a solid #Ubuntu base and the UI feels far more consistent and robust than either KDE or #Gnome - but my essential #Java app, the #JMRI #ModelRailway control software, looked awful at any scale. Jagged fonts, boxes overflowing, etc.

After a lot of searching I found a shell command to force font anti-aliasing for old Java apps (comment if you need a link to the Gist), and with a few more tweaks finally all was well.

Pop_OS, like MX Linux, seems to be AI-neutral rather than overtly AI-positive like Fedora, so I've achieved my original goal, even if it took me in an unexpected direction.

Well, it works. But not for me.

What i had in mind when i thought i could get used to a hidpi display while using #windowmaker #dockapps and a bitmap font?
It turned out to be easier to get back to a lower resolution display than to unrice my desktop and get used to a new one.

So i reinstalled the original 1600x900 display; and am selling the new one.

If anyone wants to buy a 2560x1440 matte display with the eDP to LVDS converter for #thinkpad #T430 (also works on T420, T430s and T420s), i am selling this one WITH* the adapted top lid cover (i had to sand down some nubs for the display to fit), so you do not need to diassemble it all and adapt; AND with the webcam and LED boards (because they are screwed into the lid).

I'm selling the lid with all stickers i had in it: only one. A single faux-leather dog-nose-like vinyl adhesive covering it entirelly (for a bonus business laptop look).

*if you do not have a T430 or do not want the lid or do not want to pay more for the lid and webcam/led boards, i can sell only the display and the converter.

Preferably to brazil or mercusur for easy (for me) shipping.

It's been a little bit since we last gave an update on what's up with #Tenacity itself, aside from testing week, so here's what's happened today.

First off, we finally got to fixing an issue with #Windows builds failing with (s)cache enabled under Ninja. We added a patch for #wxWidgets in our vcpkg fork that we'll upstream over to wxWidgets.

Next up, we're making some Windows manifest tweaks. Basic, but we'll focus on improved Windows #HiDPI support after that work is merged.

New Apple Silicon M4 and M5 HiDPI Limitation on 4K External Displays

My current thinking is that in order to make a resolution independent UI toolkit one must first have a resolution independent drawing library?

The things I've found on that were algorithms based on device independent pixels.

Is that still actually the state of the art?

My primary design constraint is that I want the scaling to be zero cost when there's no actual scaling happening.

Can anyone point me to some good books/posts on the subject?

Is it just me, or is Hyprland’s "auto" scaling a bit much?
On my 16" (2560x1600) laptop, Fedora defaults to 1.25, but Hyprland jumps straight to 1.60. It makes my screen feel like a giant tablet.
What scale are you all running for 1600p?

Many notebooks and tablets now ship with displays that aren’t quite HiDPI, but are more pixel dense than traditional displays. In OS 8.1, we now support fractional display scaling in the Secure Session

#HiDPI #linux #elementaryOS

We have a quick question: how is #HiDPI support in #Tenacity compared to the latest version of #Audacity on #Windows? What about on #Linux?

Just a little curious to see how the state of HiDPI support is between the two right now 👀

On my laptop, I'm using #Gnome 48 in #Debian Trixie, under Wayland. There are two 1080p displays connected, and it also has a 1920p built-in screen which I'm using with 200 % scaling.

If I use Gnome's builtin screenshot tool, all screenshots from the 100 % screens are blurry: It's scaling up the 1080p screens, interpolating pixels.

Here's an example screenshot dragged across both screens, #HiDPI on the left.

The issue is: It's also blurry when screenshotting only a 1080p screen.

Suggestions?

Иконки прямо в коде: как мы избавились от assets, портируя приложение на Linux и macOS

Привет, Хабр! Мы в ChameleonLab разрабатываем тулкит для стеганографии, который уже работает на Windows и macOS . Сейчас мы портируем его на Linux, и, как это часто бывает, именно на этом этапе классические проблемы с ресурсами (иконками, картинками) проявили себя во всей красе. После релиза пользователи увидели наше решение и стали спрашивать, как оно устроено и почему приложение не тащит за собой папку с картинками. Раз уж сообществу это интересно, мы решили дать развёрнутый ответ. Расскажем, как встроили все иконки прямо в код с помощью SVG, и как внутренние итерации и поиски идеального решения привели нас к финальному варианту.

Trying to get started building a desktop application with a #3D viewport using #Vulkan and #Rust on #Linux.

What. A. Frustrating. Mess.

Fast moving (and breaking) APIs. Outdated examples. Missing features (looking at you, #HiDPI support).

I guess I'm coming back later.

Currently, the most stable approach seems to be #GTK4's GLArea and plain old #OpenGL.

@theDuesentrieb I asked for the highest-spec computer the company would buy me (which turned out to be an Apple MacBook M2). I then promptly installed a QEMU-based emulator and installed Debian Linux into the emulator. The emulated disk is fully encrypted. I allow the VM full use of all CPU cores and 100% of all memory and disk space.

If you do get a Apple computer, I highly recommend you buy UTM from the app store, it is by far the most cost-effective option, and works extremely well with Debian Aarch64. Once you install the qemu-guest-agent package onto Linux, the Linux screen resolution will automatically match the #MacBook, copy-paste works seamlessly between #Linux and #MacOS. Desktop environments like #Cinnamon, #Xfce, #Gnome, and #KDEPlasma all allow you to select #HiDPI scaling which allows Linux to take full advantage of the #Apple “retina” display (it looks beautiful). The one and only drawback is that #QEMU cannot use Apple’s hardware multimedia codecs, so it falls back to software codecs, and the CPU just can’t keep up with things like video conferencing, or often even ordinary 720p video playback. I use Mac OS for only multimedia applications and video conferencing. For everything else, I continue to use Linux.

I recommend the bridge networking adapter so you can have two-way network communications between Linux and MacOS, this allows for file transfer between Mac and Linux via rsync. The trade-off is that every time your Apple computer switches computers networks (e.g. between home and office), you must reset the networking services in Linux. If you choose the NAT network option Linux will always have network access directly via the MacOS interface, but you will not be able to easily transfer files between Mac and Linux.

The keyboard is the hardest thing to get used to, mostly that “super” and “alt” are swapped. Be sure to transpose those keys in the #UTM configuration. It is easy to configure the Apple keyboard to (for example) make caps-lock another control key.

2025, the year I switch from wayland to Xorg.

Why? Because I bought a new screen.
Huh? Well, I don't know either.
Plasma 6 on wayland worked fine with my fullhd-screen. Yesterday, I powered the box down, switched to my new hi(gher)dpi screen, powered it on, got the bios post, boot messages, and a black screen instead of sddm. An hour later I found that sddms wayland support is experimental still, so I switched it to X, and got a black screen when my plasma-wayland session was to start. So, switched to plasma-x11 and everything is fine.
Other compositor (tested sway) are fine. 🤷

Don't know if it's nixos or plasma, I'll probably try a live usb later.
So yeah, it's the year 2025 and I'm on X. Well, could be worse, could be the other X.

I officially have a usable Arch Linux with #KDE on my desktop. KDE looks great on a #hidpi display.

Slowly adding back things I used to use on Windows. Installing and configuring stuff is a bit of work, and there are some bumps, but settling after feels nice.

#archlinux

Was playing around with the #MacMini. Hooked up #HDMI to my #4K monitor expecting to be able to use a scaled resolution (in my case, 3072x1728 #HIDPI). Wouldn't work. Only worked in #LODPI. Then I read this article - a little disturbing. Apparently the M4 can't run HIDPI 4K across HDMI. But I CAN run it with a dumb TB -> dongle -> HDMI setup like I was forced to do on the Macbook Air (due to no HDMI port). For real?! That is fucking STUPID. https://forums.macrumors.com/threads/for-lg-oled-users-mac-mini-m4-does-not-support-hidpi-4k-over-hdmi-2-1.2442797/

Anyone here using #hidpi scaling under #wayland in any shape or form, besides #plasma? And can compare the two? I am using #labwc as my #wm and I struggle to get as sharp scaling for some apps compared to what #kde does, although I am not sure if it uses the real wayland or #xwayland... everything so confusing. But if anybody has input I would be eager to hear.

Hacker bunny at work. Bunnies prefer 10" with mushy keyboards and can handle tiny fonts on #HiDPI displays.

I offered carrots but she's hacking just for fun.

#DailyStandup (1/2)

Since Friday:

> If I bum @amerl's #FrameworkLaptop then #HiDPI tools are going to improve this weekend.

- Concrete ideas for HiDPI troubleshooting tools
- Tracked down the bug in #Tk that causes some apps (like `git gui`) to not have HiDPI text (while others like `gitk` are unaffected). It's already fixed in 9.y beta, so I need to convince them it's worth backporting to 8.6.z stable.
- Reproduced a bug in the #KDE Plasma6 screen locker that had been closed as fixed.

#DailyStandup

What I did today:
- In Boston for #LibrePlanet!
- Figuring out the flow of data through the gotk4 generator so I can get the I for I need to the right place.
- Had a good time catching up with people at the @fsf office.

Challenges:
- My laptop's charge port has decided to not work. On the bright side, if I bum @amerl's #FrameworkLaptop then #HiDPI tools are going to improve this weekend.

But, seeing as my issue is one of #acessibility, you need only turn on "Accessibility > Seeings > Large Text" under #GNOME settings, which does give you the same 1x scaling UI elements, but with bigger text - which... takes some getting used to.

I dunno, guys. Larger text, or fractional scaling. Which is best? Mind you, I have a 1080p screen with high pixel density - which is like having the #HiDPI equivilant of an honourable mention.

Early versions of #Windows (up through the 9x series) had an option for "Large Fonts" in order to make text more legible on #HiDPI displays (which, at the time, meant >72 dpi or so), but applications were rarely optimized for it. You'd often end up with labels larger than buttons or text spilling out of controls. Many readme files included a note telling you to use Small Fonts to avoid problems.

When it *did* work, though, it looked pretty good.

#retrocomputing

Nvm, #kali has a #hidpi mode. Now it's perfect. Gonna setup my laptop later to be able to connect to it.
