Optimus / Graphics cards
Switch off NVIDIA card
# echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
Switch on NVIDIA card
# echo ON > /sys/kernel/debug/vgaswitcheroo/switch
Using the following command before and after the switch, you should see a drop/rise in mW being used:
# grep rate /proc/acpi/battery/BAT0/state
You can also completely disable the NVIDIA card and only use the Intel onboard graphics card ( which has more than enough performance for day-to-day work:
# echo "blacklist nouveau" > /etc/modprobe.d/blacklist-nvidia.conf # update-initramfs -c -k all # reboot
Trackpad
Cypress trackpad. Does not seem to work on Ubuntu. However it was reported to work on a stock 2.6.39 kernel on Gentoo, so must be a module/flag/option somewhere.. Adding i8024.nomux etc ( as seen on several forums for other laptops ) does not enable the trackpad on the 15z.
