https://bugs.kde.org/show_bug.cgi?id=469590 Zamundaaa changed: What|Removed |Added Resolution|--- |UPSTREAM Status|REPORTED|RESOLVED --- Comment #21 from Zamundaaa --- The drm_info output shows two outputs, one for the NVidia driver, the other for simpledrm - both attempting to control the same physical monitor. So this is a driver / distro setup problem. I don't know too well where to start looking into this, but you can probably ask about this in https://discussion.fedoraproject.org/ -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=469590 --- Comment #17 from Zamundaaa --- Please answer my question: did you have both monitors plugged in while getting the drm_info output, or just one of them? If you don't remember, attaching a new output of drm_info while only having one display connected would also work -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=469590 --- Comment #16 from Wilbur Jaywright --- Was having kind of similar issue in Wayland desktop. Now with no tablet connected and all background apps closed, I finally got a clean session running. Note that the background apps should NOT cause such performance lag. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=469590 --- Comment #10 from Zamundaaa --- you have simpledrm and NVidia at the same time, which might explain the problem. Does your CPU have an integrated GPU, and did you change any kernel boot arguments? Can you attach the output of drm_info executed while sddm is active? The simplest way to get that would be with ssh from another computer (or phone) -- You are receiving this mail because: You are watching all bug changes.
