I've been checking your driver, and it always seems suspend/resume methods are called. It's; DRIVER_MODULE(acpi_agp, acpi, acpi_agp_driver, acpi_agp_devclass, 0, 0); version. > > However, getting my screen back doesn't work yet. So there might be more > > too it.

I tried to find the spec for DPMS but it seems to > be a closed on (at least to non-members). It seems that old laptops don't have VGA specific ACPI objects, so many people will be happy if we can implement non-ACPI VGA driver w/ ATI chips hack. BTW, have you checked for XFree86 code? Hopefully we might find some hints on DPMS for ATI chips. > I'm back to where I started basicly (besides knowing more about acpi now). Never mind. I know one more guy who writing ACPI VGA driver, takawata-san(takawata@axe-inc.co.jp). Could you send him your latest code and contact him?
