I have laptop with Optimus technology so it is without dedicated multiplexer. Intel GPU is proxy for Nvidia GPU. First Linux I installed on this laptop was Ubuntu 12.10 and by default it disabled Nvidia GPU. It is good behaviour, under Linux and OpenBSD I want Nvidia GPU to be disabled. Nvidia GPU is useful for me in Windows (example Autodesk's Inventor) so I don't want to change laptop. When I installed OpenBSD 5.5-current Nvidia GPU is enabled and is consuming a lot of power and heating my laptop to 64 Celsius degrees (°C) in idle when CPU was underclocked to 800 Mhz... For two weeks I was searching for solution but I haven't finded it (I am not familiar with *BSD systems) so I decided to remove OpenBSD from laptop :/ But I had searching for solution further and in FreeBSD forum (in 9.2 they have version from 2013) I finded that it is a way to disable Nvidia GPU via acpica. Unfortunately on Liux forum there was an user who claimed that in his VPS acpica in OpenBSD 5.4 is old and can't send any signals to some devices. Should I question him about details?
I am a regular user who just want some security in Internet, I don't how programmers are dealing with hardware, I can just write very, very simple program in C and this is all my hacking skill :/ Od: "Daniel Dickman" <[email protected]> Do: "Lampshade" <[email protected]>; Wysłane: 17:24 Wtorek 2014-05-20 Temat: Re: ACPI Component Architecture > > On May 20, 2014, at 11:08 AM, Lampshade wrote: > > > > > > Hello > > > > Is there any chance to include to current and in future to 5.6 newer > > version of acpica > > package?
