Author doesn’t even compare it to a second solution.
Interesting to know, but I just use a hot key to attempt reconfiguration if something goes wrong. Works for me even if it’s not a sign Linux is ready for non-technical users.
Yes, I didn’t want to analyze and compare different solutions, I just wanted to share the joy of finding a solution that works well for me.
Using hot keys is nice, but hot keys (intentionally) don’t work while my screen is locked. I contemplated mapping an xrandr call onto a smart button (Shelly Button 1, essentially triggering an HTTP request), but in the end grobi has the same effect and is even more convenient than having to press buttons.
im sensitive to coil whine and i hear it everywhere : computers, light bulbs, phone chargers, you name it and if im in the same room as electronics i hear a high pitched squealing that others seem not to notice or care about. its inescapable and it sucks
I use both Linux and Mac, and in my experience Mac's handling of multi-monitor setups and, specially, of them changing, is only slightly better than Linux's.
For most situations you do not need to do anything difficult to plug any number of monitors to a Linux computer with a modern, full-featured distro, other than arranging them. Mac does a better job of remembering your setup and adapting to a monitor disappearing, but it's not that much better.
I'm still not sure I understand why the author needed this tool, may be because they have more than one computer plugged into the same monitor?
Both Gnome and KDE handle (un-)plugging external monitors just fine. And Wayland has been the standard in all relevant desktop distributions for a couple of years now.
It should work with tiled output, so long as a) it reports tiled geometry in DisplayID b) the driver handles it right.
Then it should show up as single display.
It's also how Apple XDR display presents itself to MacOS (two DisplayPort 1.4 tunnels over USB4, tiled layout in DisplayID).
I suspect it's possible that it doesn't have a valid tiled geometry block, but that's something that was already handled right when first 4k displays landed, so...
Debateable. But it sure started with huge step backwards. On X11 all relevant functions are at least standardized within the xrandr protocol. On Wayland you don't even have that. So it really depends on the compositor if it works or not where each is doing its own thing which is just crazy. I prefer the 70s standardization model of "mechanism, not policy".
>the monitor draws 30W even in standby
That's absurd. There are regulations on standby power.
https://dl.dell.com/manuals/all-products/esuprt_electronics_...
>Power Consumption
>0.2 W (Off Mode)
>0.3 W (Standby Mode)
Doesn't seem to be an isolated case:

>UP3216Q, drawing 23 watts in Standby? (2019).
I guess a takeaway from OP is to measure your actual standby power draw.
i hope more overlapping regulations than what energy star covered
Energy star is going away.
So the solution is to complain and get a replacement unit it seems.

My windows laptop disconnects my monitor sometimes seemingly randomly. A sign that windows is not ready for non-technical users?
Hardly, given the mountain of evidence to the contrary.
You’ve never had to support windows non-technical end users I see.
That's a silly assumption, and a silly point. By that reasoning, no OS is suitable for non technical users.
It's 2025. You really shouldn't be using X11, which is effectively end-of-lifed.
There are still plenty of reasons to use X11, mostly for software that doesn't support Wayland yet.
Or: stable and finished.
We should be using Rio then?
> Does grobi work on Wayland?
See kanshi, which has a similar rule matching approach.

I used to be. One high speed camera I could tell the frame rate consistency from the flash recharge whine.
But one day a young engineer asked if I could hear my circuit when the load changed.
I could not. I have become what I hated. The cycle continues.

So once again you need to DYI your monitor configuration for Linux that for some reason works out-of-the-box pretty much in Windows and MacOSX
sigh
And that's for X11, which was built in a 70s model while Wayland leisurely moves forward

The Dell UP3218K monitor I describe does not work “out of the box” on any OS. Even finding a GPU that can drive it at all is tricky.
It should work with tiled output, so long as a) it reports tiled geometry in DisplayID b) the driver handles it right.
Then it should show up as single display.
