#HiDPI

2025-05-21

@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.

@nerm_nelly ni, and most shut doesn't scale on non-#HiDPI or #PortraitMode!

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.

@joel I mean, #SystemD wasn't done by #Poettering because he had no hobbies - far from it.

SystemD, like #Wayland and #PipeWire is a "necessary evil" because the preexisting solutions are slow, not adaptive, cumbersome or just don't work well at all (i.e. mixed (#DPI & #HiDPI) screens with #X11 are just broken!

  • People had years if not over a decade to fix those but they didn't and it's clear that a new & clean slate was necessary...

Was playing around with the . Hooked up to my monitor expecting to be able to use a scaled resolution (in my case, 3072x1728 ). Wouldn't work. Only worked in . 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. forums.macrumors.com/threads/f

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.

@thelinuxcast I'd be interested to know how you made i3wm/Xorg work with your strange #monitor 🖥️
With #HiDPI and various scaling changes, I can only work with #wayland and #wlroots or #plasma

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.

#Hacker #Bunny #Plush #Laptop #MrRobot #Linux #MXLinux

A handmade bunny with gummy bear necklace is sitting on a small tablet computer with detachable keyboard. There's two terminals open on the screen showing lots of text. A USB SD card reader is nearby. The bunny is wearing a blue hoodie with patterns, hood pulled over her heard, long ears tucked half in.

A human sized keyboard is partially visible in the background.

@tewha Yeah, #DPI and handling mixed-DPI / size setups is something neither #Xorg nor #Wayland nor #Apple's not Xorg system do very well if not at all...

Really annoying bug where my mouse pointer is smaller in Firefox only. Anyone else got this? #opensuse #i3wm #hidpi

#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.

#Retina #HiDPI #P3 #WideGamut screens transformed the way we perceive digital content forever. Crisp texts, vivid colors, deep blacks.

I do miss the years when I could look at a screen, and deeply appreciate how artists designed the way their pixels bridged the gap between an imagined world and the real world. Elegant pixel fonts, smooth dithering, skeuomorphic art. Ah the #nostalgia

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

In "A Maze of Twisty Little Pixels, All Tiny" I discuss the state of #HiDPI support in #Linux, #X11, #Wayland, #Gnome, and #KDE #Plasma. I note some bugs in both #KDE and #Gnome, with the more serious ones in #Gnome, and discuss my eventual decision to use #KDE on my HiDPI #Framework #laptop. I also link to some patches that clear up the little bugs in KDE in this scenario.
