Unfortunately, yes. Suspend/resume never worked for me after APM is gone... (This means ACPI never allowed me to suspend/resume.) I preferred safety on update rather than convenience of suspend/resume. IIRC, in APM era, ATI (!) dGPU (no internal GPU existed) could sanely suspend/resume. Already cannot confirm, though. I started using nvidia dGPU models when no accelerated drivers were provided for newly shipped notebooks with Intel or ATI (AMD) GPUs (interlal or descrete). ITOH, nvidia "usually" provides their FreeBSD drivers before notebooks are discontinued. *There WAS a crisis, though, WRT FreeBSD kernel functionality. Once Linux kernel functionality that graphics drivers use become fixed (no more KPI changes needed) and FreeBSD LinuxKPI catches up with it, I can choose any notebook with (non-nvidia) internal GPU only or with AMD dGPUs. -- Tomoaki AOKI <junchoon@dec.sakura.ne.jp>
