Re: xorg option to switch GPU
Battery liveliness can be affected by many factors on GNU/Linux platform. 1) Make sure you use on demand CPU governor or powersave one. 2) Install laptop-mode-tools which can slow down your disc when on battery 3) Check your power management (in my case gnome-power-preferences) to tune screen light and other features 4) Make sure services You use are battery safe. For example if You use hdaps, install latest version from tp-smapi source. This one does not poll continuously from sysfs and also saves lots of battery. 2009/8/16 logangt : > Hye @ all, > i own a dell xps 13 since january of this year.

xorg option to switch GPU
Hye @ all, i own a dell xps 13 since january of this year. This laptop has hybrid sli which is not supported in linux. I want to know if it's possible to configure xorg to use only the onboard GPU and switch the powerful one off? In vista i reach more than 4h batterylife in study modus (have some PDF open and hear music) by the same activity, in linux a reach only 2h. I have tried with "BusId 'PCI:2:00:0'" but it does't work! (i toke the 2:00:0 from "lspci" output PS sorry for my English here is my xorg.conf # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 1.0 (buildmeis...@builder62) Mon May 11 15:57:20 PDT 2009 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 InputDevice"Keyboard0" "CoreKeyboard" InputDevice"Synaptics Touchpad" "CorePointer" EndSection Section "Files" EndSection Section "Module" Load "dbe" Load "extmod" Load "type1" Load "freetype" Load "glx" EndSection Section "InputDevice" # generated from default Identifier "Synaptics Touchpad" Driver "synaptics" Option "Protocol" "auto-dev" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" Option "SHMConfig" "on" Option "VertTwoFingerScroll" "true" Option "HorizTwoFingerScroll" "true" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Unknown" HorizSync 28.0 - 33.0 VertRefresh 43.0 - 72.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce 9400M G" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor"Monitor0" DefaultDepth24 Option "NoLogo" "True" SubSection "Display" Depth 24 EndSubSection EndSection -- View this message in context: http://www.nabble.com/xorg-option-to-switch-GPU-tp24991717p24991717.html Sent from the Free Desktop - xorg mailing list archive at Nabble.com. ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
