--- Comment #2 from Parker Reed <parker.l.r...@gmail.com> --- Thanks to a wonderful contributor over on Reddit, finally realized what exposed this issue. My custom EDID setup was already in place when this started. The DisplayPort dock that I have will not drive to monitors at the full refresh rate. So I already had a custom EDID with a single mode single refresh rate set for both of those. Guess which two those were, both portrait. I used a basic EDID generator for the mode and refresh rate which doesn't set a serial number. On top of that I used the same file for both of them in the kernel command line, so to the system they were essentially the same monitor with an nulled out serial. My "solution" of creating to EDID with different names worked because Plasma then have something to differentiate them by even with a blank serial. Wayland with the same EDID works as it already names them as "unknown <connector type>" programmatically. For the X11 issue at hand, I get that it was my EDID with the same nulled serial causing the issue. I know those get used a lot so probably not the first to run into it. Will be interesting to see if there's anything that can be done there. Thanks. -- You are receiving this mail because: You are watching all bug changes.
