I'm sitting here with a 4k 32" monitor and a 1920x1200 24 inch side by side, scaled perfectly so both are pretty and readable, in xfce, and when moving things between screens nothing changes size, or re-renders weirdly, or can't be resized due to invisible boundaries, or ...
It's better than windows or MacOS can manage with the same setup.
I'm not sure what you count as 'proper', and yes I had to write a two-line script with xrandr commands so ease of use isn't massively present. But the underlying system absolutely has great scaling support.
Graphics drivers are also fine these days, I've not had any problems with my mouse either. Hardware in general "just works" better than windows these days, with older devices supported and no drivers to hunt down on the web.
I'm not trying to claim it's better for you, only you can decide that. But it works great for a lot of people.
You didn't understand the problem mentioned by GP. Neither of your monitors requires HiDPI scaling. Your first monitor has approximately 138 dpi and the second a paltry 94 dpi.
Compare that to a 2012 MacBook Pro that has a 15.4-inch display with a 2880x1800 resolution. That's 221 dpi. The hallmark of a HiDPI is that its DPI is so high that you need to render UI elements at 2x or more (though sometimes 1.5x also works), so that originally a one-pixel line becomes two pixels wide. This requires support not just in drivers and the OS, but the application. ArchLinux has an entire wiki page discussing application support: https://wiki.archlinux.org/index.php/HiDPI
I beg to differ, 4k/32 does need scaling to my eyes. I don't want things to be that tiny.
Not every application needs to support scaling, so long as the GUI framework they use does, and the window manager does (XFCE has support, which I have activated) that makes the 4K screen more usable to me (while allowing the full res to be used for smooth rendering), then I use xrandr to scale the lower-dpi screen back down so elements are the same size across both. Sure, there are a few apps that don't behave brilliantly, but they aren't things I use much.
Like I said, it works better for me than MacOS or Windows (I have both, and a 2103 Retina MBP I still use).
For stuff like this, Linux is bullshit. For many desktop usecases, Linux is bullshit. After a Skype call I need to kill the app else the process takes my CPU usage to 100%. Why? God knows. Probably the same reason my lock screen sometimes shows a password prompt when I press 'Esc' or 'Enter' and sometimes it requires me to click the mouse. Did I mention I spent the last nine months without a working microphone because the drivers for my new Thinkpad hadn't made their way into any major distribution??
Don't get me wrong. I love Linux. I'd take its broken ass over Windows any day of the week. But fuck me if I don't miss macOS.
Pretty sure it doesn't :) That '1200p' screen I have certainly isn't in need of scaling for usability, but I have scaled it to match the size of screen elements on my 4k screen next to it.
I've been going back and forth between MacOs and linux a lot lately, been using my Mac as my work laptop for the last couple of years, now that I'm working remotely 100% I figured I'd switch over to linux. Honestly not having much issue with it, bar the odd "Teams has decided it can't use your headset microphone, for reasons" error.
Never even heard of Dia, let alone had call to use it. Just installed it and yes, for unknown reasons it doesn't seem to scale does it? Which is odd given it's presumably a gtk3 app and others do scale just fine. Looks like GIMP is another one that's not onboard yet.
My daily use at the moment is IntelliJ, MS Teams, Skype, Firefox and Steam. I guess gedit, meld and a few other utilities. They all seem to be fine. Perhaps my relatively constrained set of requirements is why I'm happy with it.
There is system76 with "Pop OS!" but I would like to see a company who's entire focus is on release a very slick OS _only_.
By all means make the OS downloadable separately, share with the community and all that, but to make a profit, you need to sell hardware. And the hardware needs to be good.
So I am about to start a new job, and the new workplace was about to send a new Macbook Pro out to me, which I didn't want. So I went to do some research for a laptop with any Linux distro preinstalled so that I could go back to them and tell them I'd rather have this.
I found out that there is no decent laptop with Linux preinstalled. System76 has some decent systems, but they didn't come close to what the likes of Dell and Lenovo offer with Windows. For now System76 seems to show most potential in this area though, so it will be interesting to see what they do going forward.
Lenovo's upcoming ThinkPad laptops include some models with preinstalled Fedora as an option:
The announcement regarding Lenovo's upcoming ThinkPad laptops coming with Fedora pre-installed came a literally 1 or 2 days after I'd already ordered the P1 Gen 2, which according to Canonical is certified[0] to run Linux correctly, and it's the reason I went for that. Regardless, the next generation would have left me without a laptop for the job.
It's been years coming but it's getting there: https://gitlab.freedesktop.org/wayland/wayland/-/merge_reque...
It always had the options there in previous versions, but it only ever honoured the value you set on a single monitor. Now, I can have my 4K monitor at 200% while I leave my laptop at 100% (1080p) and it works perfectly.
If only it handled Bluetooth audio devices better it'd be perfect; Currently, I can't connect a pair of truly-wireless earbuds and play audio out of them without using Blueman to mess around with the audio sink settings etc each time I connect them. On my desktop, with Manjaro (KDE) and an Intel AX200 WiFi/Bluetooth I can connect both the earbuds (with no additional tweaking) and for example an Xbox One S Bluetooth controller (with the minor tweak of disabling etrm), and they both work perfectly.
I'm not sure how much of that is related to Gnome/KDE but Ubuntu really could do with some better Bluetooth device handling, especially for audio devices.
Welcome to the world that Fedora users have been living in for years already. Ubuntu users can thank to Canonical's decision not to enable Wayland in 18.04 for that...
If it really was intentional, a small dialog or log that explains _why_ I couldn't scale monitors differently would have sufficed, or, simply moving the percentage adjustment control out of the settings for each display.
On that note, 20.04 is supposed to support fractional scaling, but if I try to turn the toggle on, it just fails silently, so are we back to square one, or did a developer somewhere decide some precondition means I can't _currently_ turn it on, but didn't feel it was worth telling me, the user, why?
In the past, when it wasn't exposed in GUI, and worked for Wayland only, it was necessary to logout and login between enabling fractional scaling and setting the scale itself (the reason was, that Xwayland was started in different mode then; technicality, that doesn't matter no normal users, but then, the functionality was labeled experimental and enabled via gsettings anyway).
The X11 fractional scaling is a different beast; it uses xrandr scaling and requires cooperation from the graphic card (the output encoder, specifically - it sets up framebuffer at different size than the output to display). That also means, that it won't work on machines that do not have output encoder at all and assume framebuffer resolution is equal to output resolution, like remote sessions or virtual machine clients. Here I agree, that some error message would be appreciated. It was also brave from Canonical to enable it for LTS, without going through a testing cycle in a non-LTS release.
With a hindsight, the remote desktop/screen sharing solutions caught up faster (except the closed source ones - they have no motivation when ubuntu works, so why bother) than figuring out how to handle several displays with different dpis under X11 so that legacy apps not using modern Gtk/Qt work.
You can do it on pretty much any modern X on linux using xrandr, FYI, it's just not easily done in a settings app. I've been doing this with xfce for a while.
My xrandr line is not that easy to read but effectively, after I've set xfce hidpi support to double the size of screen elements, I increase the view window of the smaller screen by a factor of 1.8, and of the larger screen by a factor of 1.2, and put them next to each other -
xrandr --output HDMI-0 --mode 1920x1200 --pos 0x100 --scale 1.8x1.8 --output DP-2 --mode 3840x2160 --primary --scale 1.2x1.2 --pos 3456x-180
If Wayland can do that without so much messing around, great :)
On X11, scaling of entire framebuffer (i.e. scaling macOS style) is a standard xrandr functionality, but it was never exposed to UI. It has some drawbacks that macOS never had to solve (how it behaves over remote x11/vnc/etc, or memory requirements for framebuffer, for example), that make it unsuitable as a general solution. It is basically one of the hacks complained in this threads.
Are you saying it would have worked had I used xrandr?
Are you sure you were running Wayland? In Fedora under Wayland, you could pick a monitor and choose scaling for it in the setting applet.
It is quite possible that 18.04 has some bugs. I don't have 18.04 machine with hidpi monitor at hand, so I can't have a look myself, so I chalk it up that there is something weird happening.
I'm using the proprietary Nvidia driver.
My XPS 13 is using Intel from an 8th gen i7.
I own a pair of Master Dynamic MW07 and a UE BOOM speaker. As for my laptop, a Dell 7470 with Ubuntu 18.04.4
I've found that without Blueman installed my earbuds will pair but are not even detected as being an audio device. I dislike having Blueman installed/running so I'd like to get it working without.
I'm running Ubuntu 20.04 upgraded from Ubuntu 19.10 on an XPS 13 (it has worked on neither). I'm tempted to test on my Ubuntu 18.04 laptop (XPS 15) to see if perhaps it was broken recently.
One thing of note perhaps, is that the XPS range use the horrid "Killer Wireless" card from the Alienware/Gaming range, their Linux driver performance has been generally horrid in the half a dozen of them I've experienced.
I must therefore conclude that something has been broken since 18.04 as it neither worked for me on 19.10 nor now on 20.04.
Unfortunately the state of Linux as a desktop OS in the past decade has missed entirely the hardware developments. No proper support for scaling for hidpi monitors, scrolling with precision mice/touch pads, no touch UI, UI is that still not deep enough and casually requires the user to spawn a terminal, graphics drivers that are still not stable and do not support the latest standards like hdr.
I wish there was a for profit company that would focus on making a polished desktop linux distro. There is only that much that the oss community can provide for free, but it is simply not enough.
