Proper configuration for Intel Meteor Lake Core Ultra 7 155H?

Hi Folks,

Could somebody please share with me configuration for Intel Meteor Lake (Core Ultra 7 155H)?

I’m running KDE Plasma on a new laptop and everything is slow. For example a web browser or VSCode is very unpleasant to use. KDE Plasma (the same configuration) on an older laptop works completely fine.

So far I found I added configuration from Intel Graphics - NixOS Wiki and I added "i915.enable_psr=0" into boot.kernelParams which (I think) it makes more stable since without it I sometime got dmesg [drm] *ERROR* gt: timed out waiting for forcewake ack request..

I’m running stable NixOS with linuxPackages_latest from unstable. The thing I haven’t tried yet is to switch from X11 on Plasma 5 to Wayland on Plasma 6 but I don’t want to change too many things at once…

Thank you.
