Hey! is nice to hear there is someone that understand my pain :P Well, when I try to switch off the nvidia card my system freezes after a few seconds. I think this is why I can't switch back to the intel card, because switchero try to power down the unused card when a switching signal is sent to. I just input # echo OFF > /sys/kernel/debug/vgaswitcheroo/switch && dmesg > paste.dat to totally freeze my system ( I have pasted the dmesg at http://pastebin.com/asu9HwEg in case someone could find any clue)
I could say that on windows 7 my battery life time (I don't know how many cells has, but is quite big) is around 4 to 5 hours. On linux instead, the laptop after 30 or 40 minutes turns out quite hot (just below the keyboard, at the location where the vga card is sited in), and the battery runs out before 2 or 2 1/2 hours. It would be really nice to be able to, at least, turn off the nvidia card (I'm totally resigned for now to not compile cuda codes :) ) Best, Dante On Mon, Jan 31, 2011 at 10:30 AM, Dawid Lorenz <[email protected]> wrote: > > On 25 January 2011 17:59, Dante Paz <[email protected]> wrote: > >> # dmidecode -s system-product-name >> *Vostro 3300* >> >> # dmidecode -s system-version >> *A10* >> >> # lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA >> *00:02.0 VGA compatible controller [0300]: Intel Corporation Arrandale >> Integrated Graphics Controller [8086:0046] (rev 18) (prog-if 00 [VGA >> controller]) >> 01:00.0 VGA compatible controller [0300]: nVidia Corporation Device >> [10de:0a75] (rev a2) (prog-if 00 [VGA controller]) >> * >> > > Ha!
