[Desktop-packages] [Bug 987401] Re: Ubuntu should poweroff video cards not in use
I also mark this bug against xserver-xorg-video-ati in order to check the status. >From what I understand, from muxless ati/intel systems there are two cases >(selected by vgaswtcheroo): a) The rendering is done by the Intel card (default case). Intel card is on, ATI card should be off to save power b) The rendering is done by the ATI card. Both cards are on (ATI for rendering, Intel for display) What I state is that in the first case, the ATI card should be off in order to save power, which is not what happens now (it remains on doing nothing). Seeing that this is the default configuration, it means that way too many hybrid systems (mostly laptops) consume around 10W of useless power, with dramatic effects in battery life. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/987401 Title: Ubuntu should poweroff video cards not in use Status in “linux” package in Ubuntu: Confirmed Status in “xserver-xorg-video-ati” package in Ubuntu: New Bug description: I have a laptop with two video cards: > lspci|grep -i vga 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: ATI Technologies Inc NI Whistler [AMD Radeon HD 6600M Series] (rev ff) I have looked around and I saw there is the vgaswitceroo module which can be used in order to turn on/off unused graphics cards and also switch the enabled one (albeit with X restarting).
