| 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. | Full multi-gesture trackpad usage does not work at this moment. It is however possible to get basic mouse functionality with the following command: ||# sudo rmmod psmouse; sudo modprobe psmouse proto=imps|| ( Or use proto=bare or proto=exps ). |

| ''(I managed to get the trackpad partly working on Debian/unstable, kernel 3.0-rc5, with: rmmod psmouse; modprobe psmouse proto=bare; or: rmmod psmouse; modprobe psmouse proto=imps ) '' |
To make this persistent, add the following line at the bottom of /etc/modules: || echo "psmouse proto=imps" | sudo tee -a /etc/modules|| |

Hardware
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
Full multi-gesture trackpad usage does not work at this moment. It is however possible to get basic mouse functionality with the following command:
# sudo rmmod psmouse; sudo modprobe psmouse proto=imps |
( Or use proto=bare or proto=exps ).
To make this persistent, add the following line at the bottom of /etc/modules:
echo "psmouse proto=imps" | sudo tee -a /etc/modules |
