    <thetext>SUMMARY

on my desktop I have two identical screens and they always show properly when booting, but after waking up from auto-off-timeout, they quite often get set to weird settings.

STEPS TO REPRODUCE
1. have my hardware..
2. don&apos;t touch computer long enough to make the screens go to sleep (the computer itself doesn&apos;t sleep)
3. touch the mouse to wake up.

OBSERVED RESULT

The configuration I boot with is applied.

EXPECTED RESULT

It looks like a weird combination of all the properties at one time or other I changed get applied.
Like, one screen gets 110% but the other gets 125%. I&apos;ve used the 125 one just once to test if that was good and I stuck to 110 for ages now.
Screen rotation gets applied randomly. Which is fun since one is 90⁰ rotated, the two screens either get 0 or 90 applied. Sometimes both 90, sometimes both 0. Sometimes correct and sometimes the exact reverse of what it should be.
The &apos;primary&apos; almost always moves to the wrong monitor.


SOFTWARE/OS VERSIONS
KDE Plasma Version: 6.2.3
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.0

ADDITIONAL INFORMATION

the screens are identical, when I press &quot;identify&quot; I get a really long Id on both, which is the same.

I don&apos;t know how to get more details about the screens...</thetext>

    <thetext>Does it happen only on X11, only on Wayland, or in both?

How are the screens connected? What physical connectors? And to what ports on your system/GPU/dock/etc?</thetext>

    <thetext>This is wayland only. I don&apos;t run X.

The screens are connected with displayport. Both sides of the cable are displayport. Mini on graphics card, full size on monitor.

I also noticed that there actually is a 1 digit difference between the two screens (its a LONG string, I missed it the first times).

All the details are in the files I attached...</thetext>

    <thetext>Please attach your ~/.config/kwinoutputconfig.json and the output of drm_info before and after the issue happens, and also attach the EDID of your screens. You can get them with
&gt; cat /sys/class/drm/card1-DP-1/edid &gt; edid.bin
(card and connector name might need adjusting)</thetext>

more local config

Added the info.
Request for drm_info is harder, I don&apos;t know where that comes from. It is not a command I have or pacman (archlinux) knows about.</thetext>

    <thetext>Okay, no need to get more information, this is exactly the same as bug 488270 - same serial number, but different EDID hash
