KDE has this feature that if you keep wiggling the cursor fast enough it gets as big as the screen, which would be useful in this situation

You can double-click Ctrl on Windows 11
Just eliminate a few of them monitors, then it's much easier.
Accidently pressed prtscn and roasted their RAM.
Can anyone tell what kind of work he's actually using those for? The image is a little too potato for me to make much out.
We have rooms like this where i work. Theyre for live monitoring jet engine tests so we can monitor 1000+ pieces of instrumention to make sure the engines running safe.
That said, that floor looks too nice to be in our kind of facility. But i imagine hes got to be monitoring something in live time. Each screen is probably dedicated to a sub-system so he knows if something turns yellow or red, he immediately knows what system it is, whats going on, and can call the test back to a "safe operation"
Many control rooms require you to keep an eye on a lot of things at the same time and have similar setups
I was idly wiggling my mouse while wating for a download and the cursor got HUGE. I didn't know KDE even had such a feature.
This has been a thing in MacOS for years, and it always felt so simple and... obvious? Well, it seems, finally someone else has implemented it
I have the banana cursor and I amuse myself daily by making my banana big banana
Link for the magnificent banana cursor: https://store.kde.org/p/1931412/
Nobody thinks of the banana for scale? How do we do now?
Someone should make a penis cursor. That would be double amusing.
I doubt it doesn't exist already
I love this feature in kde, if only just to amuse
My use case (other than amusement) is to point out something on the screen to my girlfriend who is on the other side of the room. Wiggle the mouse for a bit until it's big and then circle the thing needing focus lol
It also got huge while hovering over Kwrite. Only once and that was a bug.
Yeah i disabled it cuz I always wiggle and it was distracting me too much lmao
I don’t think this crazy number of monitors will be doable in KDE, but curious to know if anyone has done it without messing with like 4 different conf files.
I have 6 monitors running through 2 very different GPUs on KDE right now, on the PC I'm using to type this. Works great, and I suspect I could add more monitors and more GPUs with no issues.

Okay, granted, there actually are some issues. My issues:
-
It seems to depend on the distro. Kubuntu and Ubuntu Studio have been able to do it just fine, automatically configuring it correctly from the first boot; no other distro I've tried to date was able to make it work, regardless of how much I screwed around with things. All other distros I tried would only ever display through one GPU at a time; they could never use both simultaneously.
-
Using two very different GPUs is maybe necessary for it to work? Using two nvidia GPUs (1070 & 3090) didn't work -- it would only ever output from one GPU or the other. Using two Radeon cards also didn't work. But an nvidia 3090 and an old Radeon together? They both work perfectly, and are able to drive displays independently. (4 displays on the 3090, 2 on the old Radeon.) My motherboard doesn't have integrated graphics, so I wasn't able to test that. (Though it has more than 4 ports, the 3090 is only capable of driving 4 independent displays at a time, which seems to be a universal hardware limitation, hence the need for a second GPU.)
-
The system becomes unbootable (boots to a blank black screen) anytime GPU drivers are updated. That one really burned me the first couple times. The solution is to just not update the GPU drivers.
sudo apt hold *nvidia*did the trick. (Yeah, I know that's not ideal. But it works.)
But now that I've got the kinks worked out, it has been running flawlessly for me for years. Absolutely insane setup, including very different displays, different resolutions, different refresh rates, but it chugs along just fine and just kind of magically works.
Maybe it's a hardware thing, but I have a Framework laptop with two AMD GPUs, and with Bazzite, they work together out of the box.
My guess is that KDE isn't the main problem. It's the video cards and drivers.
Yeah, I build a 4 display setup for my son with 2 hdmi splitters and 3 almost identical displays ( model code in one was slightly different even though had bought 3 same displays ) and one older one from different manufacturer with same specs.
Many desktop environments only saw 3 displays OOB. KDE was able to use 4, but it was unstable, especially with games and restart juggled the display order. Some trial, error and tweaking fixed most problems, but there was still some serious unstability due to different display models and spitters inability to fully reconcile differences. So, in the end it was a hardware problem.
He still used that setup for a while.
When my son settled on i3 desktop, solution was to buy a 4K TV and spit it to 4 displays with xrandr. Worked perfectly even with games (window borderless). He still set up a hotkey that made the 4 displays in to one, if some app/game didn't like the split.
I took those 4 displays because I had a multi-device setup and I needed a new display and was tired of using HDMI switch.
Windows: install power tools then double tap ctrl.
Linux: search "locate pointer" a lot of desktop environments support this natively, or you can extend it power tools style. On GNOME ctrl should also highlight the cursor.
Hell, Windows has had the locate cursor option natively since like XP I think.
I've had to turn it off forever since I'm a bit spastic on the keyboard, haha
On KDE you just shake it

Find My Mouse. Double tap cntrl and it shows you where it is.
What kind of hardware do you need to run 15 screens?
Four GPU's with four outputs each would do it.
You'd only need a main board with for x16 physical slots as PCIe x4 would be sufficient bandwidth for desktops.
You're also not pushing the GPU's power envelope, so one beefy or two smaller PSU's would suffice. The AMD WX7000 series workstation cards don't even have the extra PCIe power connectors (last time I looked).
I suspect these are more likely to be two or more machines though.
AMD GPUs used to be really good at this. Not sure how well it works nowadays, with generally higher resolutions and thus higher bandwidth requirements. I'd imagine it involves a lot of trial and error with displayport chaining.
Matrox cats are even better. 8 displays per card.
TIL Matrox still exists. I think I used to have one of their cards in the 90s, but I don't remember which.
A modern computer can easily fit 4 low-end GPUs plus the onboard one. Most things that used the slots are onboard the motherboard or USB now.
That's not what it looks like in my PC, but I guess you might be right. Although it seems that most motherboards, people can actually afford come with far fewer full PCIe slots.
If you can afford 15 huge monitors, you can splurge on the motherboard with extra PCI-E slots.
The cursor problem seems like it wouldn't be there with a tiling wm.
It's because with tiling vm you don't need multiple monitors 😀
They're still handy but I have no clue what I would do with more than 3 screens outside of highly specialized cases.
Really?
I had 4 once; þe fourth was running gotop. I had to get rid of it because it was DisplayLink and was always causing DPMS grief.
I'd like to have up, and visible at all times:
- top(s). I have 6 servers, plus my desktop - I'd like monitors for each of my always-on systems.
- an audio player
- IM
- chat rooms
I'd raþer be able to see activity in my peripheral vision þan have notifications popping up; I can tell by geometry which app it is if þey're all visible, and know wheþer I want to pay attention at þat moment. Notifications require an attention shift to determine which app and wheþer I want to shift attention.
Þen, I need to have two terminals visible and one browser. On a single 4k monitor, I can barely squeeze two useful terminals in, if one is short, next to a browser window.
Don't you have several programs which are easy to ignore but which would be handy to be able to glance at?
My current role gave me an ultra wide and a second monitor mounted vertically
Almost immediately turned off the second monitor, and the ultrawide I maintain my terminal in a more standard widescreen area
I really hate distractions outside my field of view
