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.

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
"Lost your cursor? That's okay, just use your mouse to double-click the Ctrl key on your keyboard and you'll find it!"
(Not what you meant of course but accidentally sounded too much like an AI slop answer, fitting for Windows 11)
So that's why my cursor randomly gets huge...
that's a neat way, as it is very intuitive. one always wiggles the mouse to search for the cursor :) at some point i had a shortcut for that, but would always forget about its existence
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.

Find My Mouse. Double tap cntrl and it shows you where it is.
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
What kind of hardware do you need to run 15 screens?
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.
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.
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.
The main limitation here is number of monitor ports.
Applications that use this many screens aren't running a high level of graphics. Even a bunch of camera feeds aren't going to strain the GPU.
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 😀
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
