Created attachment 178285 [details] 6.2 Version on Heading, and 6.3 on details SUMMARY I just ended updating KDE Neon to the latest version (that is 6.3.0), the issue started after I changed the new feature named Color Accuracy on Display Settings, the issue continue even after restart. The screen will go black again after login. That said, this issue only affects Wayland, because X11 is working just fine. Can you please tell me which file I have to delete in order to make Wayland work? STEPS TO REPRODUCE 1. Right click on Desktop 2. Change Color Accuracy from default to the other value (sorry, I don't remember) OBSERVED RESULT Screen will freeze and will go black after login EXPECTED RESULT I don't know :( I was testing the new features listed on the "what's new page".

Thank you for the bug report! This issue has already been filed, please see the linked bug report for some information on how to restore operation until a proper fix lands. *** This bug has been marked as a duplicate of bug 499789 ***
In order to fix the issue; read the bug 499926. I mention the fix for it in the description.
I could recreate the issue by changing Color Accuracy to "Prefer color accuracy", and then the screen went blank. I tried to solve this with these steps: 1. Start in text mode (Ctrt+Alt+3) 2. Removed iccProfilePath from ~/.config/kwinoutputconfig.json. 3. Executed: killall plasma_session 4. Then I got a blank screen after login. I have to use X11 in order to use my desktop. Additional info: KDE Neon 6.3 Plasma version 6.3.3 KDE Frameworks 6.8.2 Kerven 6.11.0-19 Processor: Core I9-11900K Memory: 128GB Graphics: AMD Radeon RX 570 Board: Z490 AORUS ELITE.
I also have a laptop running Fedora 41 and the latest Plasma, it appears that one is not affected.

I fixed it by editing the file ".config/kwinoutputconfig.json" and changing "colorPowerTradeoff" to "PreferEfficiency", from what i know, deleting iccProfilePath will not do anything unless the ICC file is the source of your issue, but if the source of your issue is the color accuracy setting, then try my fix.
