Bug 496989

This looks like a recurrence of bug 468546

Is this monitor connected to a laptop, or is there a multi-monitor setup?

Not a laptop.  Standard desktop single monitor configuration.  Not impacted by resolution changes.  Connecting additional/external monitors is untested.   Simple disconnect/reconnect of established (hdmi) monitor causes this.

FWIW, this problem seems to be new with 6.2.x - does not exist for me in Plasma 6.1.5 / Frameworks  6.6.0 / Qt 6.7.2.

Does it reproduce on Wayland, or is it X11-specific?

Agnostic.  Happens both for Wayland and X11.

I attempted to replicate this by connecting my git-master laptop to a monitor and setting that as the only display.
After disconnecting and reconnecting the monitor multiple times, all the desktop icons stayed in place.

I'll leave this open in case someone else can reproduce it.

I'm not sure this problem exists on laptop + external display.   This happens on the desktop with a single monitor.

After screenshot

I am also seeing this on Wayland. I have two displays connected (a 1440p monitor and 2160p TV), but only one is enabled (the 1440p monitor). If I power off the enabled display, icon position is lost.

Unfortunately I find myself powering off the display somewhat often to work around either a bug either in the monitor itself or in the amdgpu kernel driver that prevents the screen from waking properly from S3 sleep.

Can confirm this even happens if Icons > Locked is enabled.

Hello,

this issue still occurs with KDE 6.2.5 when you change the monitor input with a KVM switch.

You can simply reproduce it by switching off your monitor and switching it back on.

Yes - this occurs even when Icons > Locked is enabled.

I tested again on git-master, powering off the monitor and back on (rather than disconnecting the cable)
I'm not able to reproduce it with a laptop and external monitor (where the display goes back to the laptop display when the monitor is powered off)
It's possible this only affects situations where the display can't revert to another screen

Note that the problem is not specific to a Laptop or an external/additional monitor.  A good test is to physically (or via KVM) disconnect & reconnect the primary monitor from a Desktop PC.   Power reset of the monitor is probably hit-or-miss also, depending on the monitor itself.  For me, this only occurs on disconnect, power cycle has no effect.

Seems to be resolved in latest update.

This is good news. Is anyone else who was affected by this bug still seeing it on 6.3.3 or later?

I'm still having it.

I'm on 6.3.3 and still have the issue.

Darn. Thanks for the confirmation.

Issue on Plasma 6.3.3

I am also experiencing this bug since plasma 6.0.5.
The update to Plasma 6.3 was supposed to resolve the issue. However, I am still encountering the same problem on version 6.3.3.
I tried deleting the “[ScreenMapping]” section in plasma-org.kde.plasma.desktop-appletsrc. When that didn’t work, I deleted the entire file, allowing Plasma to rebuild it from scratch. Didn't help.
When I power off my monitor, the icons rearrange themselves. 
I am using a 1920x1080 resolution.

Example of rearranging icons

The section of the black screen appears when I power off my monitor.

A bug causing desktop scrolling when the monitor is powered off

This bug is also capable of causing your desktop to scroll.

*** Bug 503426 has been marked as a duplicate of this bug. ***

Just upgraded to plasma 6.4.  Problem of icons rearranging when monitor is powered on still exisis

This sounds very similar to bug 490891.

Can anyone still reproduce this in Plasma 6.4.4 or later? We made a bunch of fixes for this recently.

Issue on Plasma 6.4.4

My Bug 494688 is about changing to a higher resolution monitor/TV and losing the organization.

Currently the icons get reset per new resolution but they should remember their positions after moving. However, reimplementing the position migration to new resolutions should hopefully now be less bug prone, so I will look into that.

After updating to Plasma 6.4.4 I rearranged my desktop icon to the way I like them (arranged top to bottom, left to right.  I have 4 columns with 9 rows with an empty 10th row.)  They stayed that way between several reboots, log ons and offs and monitor power cycles.  However, a few days later I noticed they layout had changed.  The second column had shifted down by two slots, the third by 3 slots and the forth by 4 slots.  What had rolled off the bottom of a column had moved to the top of the next column.  I tried manually rearranging the icons but they would not go to where I moved them.  They would instead fill in an empty slot near where I tried to move them.  I logged off and back on again and the icons were back to their original positions.  I'm guessing that the grid pattern got messed up some how when I turned on the monitor.  Maybe a different issue?

This specific bug should be fixed with https://invent.kde.org/plasma/plasma-desktop/-/commit/666e69d230abf51518ae812caad083ff91b32384

Seems that will be part of 6.4.5

I have two monitors.  The primary one directly in front of me is the primary and has the icons.  The secondary is to my right.  Both set to same resolution although the primary is the larger of the two.   27 inches for the primary and 24 inches for the secondary.  If I turn on the secondary first and then the primary, all is ok.  If I turn on the primary first and let it  light up, the icons are ok, but then I turn on the secondary, the icons on the primary shift as I described above.

Was this with the patch I linked?

Don't know for sure.  I keep the system updated from the Fedora repositories.  If the patch was included in the latest release, then yes.   Here's what I currently have:

Operating System: Fedora Linux 42
KDE Plasma Version: 6.4.4
KDE Frameworks Version: 6.17.0
Qt Version: 6.9.1
Kernel Version: 6.15.10-200.fc42.x86_64 (64-bit)

Processors: 16 × 13th Gen Intel® Core™ i5-13400
Memory: 16 GiB of RAM (15.4 GiB usable)

Thanks, it's not in your version yet then, it will be in KDE Plasma Version: 6.4.5

I'm setting this as needsinfo - waitingforinfo, since I currently don't have good setup to repro your issue.

Feel free to reopen this if you have the issue with 6.4.5 when it lands to Fedora, and if not, you can just let it autoclose. :)

Thanks!

Just upgraded to plasma 6.4.5.  Problem is still not resolved.   It seems that if I turn on the larger, 27 inch primary monitor first, all is ok.  If I turn on the smaller, 24 inch secondary monitor first, then the icons are rearranged.  The opposite of how it behaved previously.

Do these monitors have different resolution?

We now save the positions completely different between resolutions. So if you arrange the icons as you want them in both resolutions, they shouldn't move around after that.

The part that "migrates" the icon positions from first resolution to the second one is still missing, and bug for that is in here: https://bugs.kde.org/show_bug.cgi?id=500868

> https://bugs.kde.org/show_bug.cgi?id=500868

Scratch that, I linked wrong bug report. But my point stands :D

Why is resolution being used for it, instead of just "B-6 block in the grid"? The scrollable Desktop could become active if the position converted would end up being out of bounds.

Oh, the scrollable desktop only goes one direction. Nevermind.

Both monitors have the same resolution - 1920x1080.

> Both monitors have the same resolution - 1920x1080.

Odd. Then there's something going on, definitely. Will investigate further.. 

But I (or some other willing poor soul) will have to fix the icon position "migration" as well.

So there is a grid, that is only scrollable in one direction, like you said.

The grid implementation is rather old and fixes have just been piled on top of it, and it probably could use another proper rewrite at some point.
