Hello fedorians, i am quite new to using linux. This morning i installed the workstation fedora 37 spin with kde plasma. In the live session as well as after installation the OS was extremely laggy. When i opened up the system monitor it showed a CPU activity between 95-100%, and the processes window showed kwin_wayland taking up my entire processor capacity.
I tried installing htop in order to document the processes activity, but the lag made it really dificult. And i cannot add a picture.
I tried searching the forum as well as google for a solution to no awail. Do you have any suggestions?
Alright, i logged in using xorg11 instead of wayland and KDE now runs smoothly with a CPU activity of between 2-3%. I did not know that switching this easily was an option. Thank you!
If you where in my shoes, would you report this? Will the developers benefit from this knowledge?
Glad you have it working now.As far as reporting it the more issues reported the better.Maybe they will get the issues worked out in time but KDE seems to not play well with wayland.
That tell me that all graphics rendering is forced to the CPU since the nouveau driver does not support hardware acceleration on an nvidia GPU.
I expect you would see a major difference in cpu usage if you were to install the nvidia drivers from rpmfusion which would enable hardware acceleration and support wayland on that GPU as well.
The T400 GPU appears to be supported by the latest nvidia drivers as well.
