As almost everyone is aware, 390.xx and later drivers have substantially increased idle power consumption on all supported NVIDIA GPUs even with the suggested workaround (
Option "UseNvKmsCompositionPipeline" "Off"
) - we are talking about ~20% more watts.
Could NVIDIA be so kind, as to extend the support for the last working drivers say for a year or two, given that you are reluctant to fully fix this regression?
