"It doesn't powerdown the radeon when its not in use yet. I know the ACPI call to power it off/on, and since I have the BIOS I should be able to repost it. So I'll try adding the callbacks into the KMS driver to do this soon. It doesn't poewrdown the intel when its not in use yet. Not sure what I can do here, since there is no ACPI method to turn it off. I think I can just D3 the GPU, and use the normal s/r paths to bring it back. Again requires more investigation. The whole what ACPI + methods map to what device, how the mux ids match etc will probably all need to be stored in the DMI table. Anything not a Lenovo W500 - probably not that hard to add other Intel/AMD variants to this, add DMI and mux switching method. nouveau isn't hooked up - this could probably be done by some interested party - the driver hooks so far aren't very hard. No idea about ATI/ATI or NV/NV ones either." So, this will not solve battery / heat issues yet. -- hp Dm3z with switchable graphics can not use fglrx graphics / disable card https://bugs.launchpad.net/bugs/486714 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
