The news is that I got reference docs from ATI that have all the info I need. It's now a mather of enough time to finish it up. I'll certainly notify the list when it is done.

Mark, any news on this issue? I'm seeing the same problems with suspend on a Dell Latitude C600 with a ATI Mobility M3...

Hopefully we might find > some hints on DPMS for ATI chips. Ok, listen to this ;-) I think DPMS might be very related, because when I suspend from X and resume again everything is (almost) fine!! 1. I start up the machine 2. startx 3. I enter S1 either by acpiconf / closing the lid / ctrl-esc (sleep key) 4. Screen goes to console and stays on 5. I resume with power key / open lid 6. Screen turns black 7. Few seconds later X is in front of me again! 8. If I now go back to the console (ctrl-f1) the console is still black I also tried the scenario where I suspend on the console, then resume again, which turns the screen black. I then startx again and my screen is back again. This is a major step IMHO. I already looked at the DPMS code in X and we have to extract that basically.

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.

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([EMAIL PROTECTED]). Could you send him your latest code and contact him?
