(video is resumed if agp, drm and i915 are loaded) Great. AFAIK, I believe drm(4) for Intel GPUs has proper suspend/resume code, i.e., rnoland moved the code to MI module and hooked it up to FreeBSD driver. Unfortunately, Linux crowd went crazy about KMS (Kernel Mode Setting) and didn't bother to implement it for other GPUs: https://fedoraproject.org/wiki/Features/KernelModesetting Since we don't have KMS, we have to implement the functionality in our MD driver modules, i.e., save/restore registers and VRAM. I believe rnoland is working on NVidia support code, though. > Now, if only same is going to happen with i386 .... I wish I had some free time... Thanks for the feed back!
