I haven't tried S3/S4 yet, but I suppose the problem will be similar on my ATI Radeon 9600 M10 NP laptop. Simple question: in which way X restores the screen? I mean, I've seen other posts on other mailing-lists about POST command which can be restore LCD after resume, but I don't know how I can do it.. Could explain me or provide some docs? Another simple question: is there a documentation about 'radeonfb'? If I compile it in the kernel, I've no problem, but as modules I get this error: radeonfb: Unknown symbol fb_find_mode > It turns out that I don't have to remove radeon (drm module), > intel_agp and agpgart modules before suspend (and insert during > resume).
