Kevin Oberman, Network Engineer, Retired > E-mail: rkoberman@gmail.com Kevin, I was already describe possible culprits of Xorg screen puzzling after resume, there is two possible candidates: 1. mishandling of system PM events by Xorg. 2. something wrong inside drm2+drm/kms drivers. but things #1 in your list points more to mishandling of PM events. btw, crash with suspendswitch=1 looks like fixed :) Thanks!
