Hey, so I finally made a judgement call and decided contrary to first impressions Canonical's Unity desktop environment is actually powerful, so I took the plunge and am running Ubuntu 11.10 on a Z570.
I'm developing a habit of jotting down notes as I hit problems installing, configuring, bugs and fixes etc and figured I may as well share them here in case they're helpful to any other Z570 owners (or maybe other Lenovo platforms). Feel free to provide input, criticise, point out alternatives, etc; there are always things I don't know.
I'll summarise in this OP and include further details in subsequent ones where suitable. My Z570 is bought from the UK high street with an i3-2330M CPU, 8GB RAM, nVidia 520M 1GB / Intel HD 3000 graphics, with a 750GB hard drive split into 4 partitions and, as will seen to be relevant, Lenovo's One Key Recovery 7.0.1628 (sizes are very approximate).
I updated to the latest BIOS (38) from Lenovo's support site (mine was 36), Windows 7 Home Premium is pre-installed and I installed Ubuntu from USB.
Starting at the beginning...
$ sudo modprobe -r acer-wmi
..and/or make it persistent over reboot by adding "blacklist acer-wmi" to /etc/modprobe.d/blacklist.conf. Via CLI (as root):
$ echo "blacklist acer-wmi" >> /etc/modprobe.d/blacklist.conf
$ sudo mount /dev/sda6 /mnt $ sudo grub-install --root-directory=/mnt /dev/sdaNote that /dev/sda6 is the Ubuntu installation partition, /mnt is an arbitrary directory on the live session where the permanent ubuntu installation partition is to be mounted, and /dev/sda is the DRIVE the installation partition resides on.
$ sudo add-apt-repository ppa:kamalmostafa/stuck-backlight $ sudo apt-get update $ sudo apt-get upgradeNote; my z570 is now running on the 3.0.0-15 kernel and the problem does indeed remain fixed.
That's it for the hardware-dependent stuff. As usual, a bunch Ubuntu tweaks and bug fixes required before everything is running 100% smoothly and to my liking but it's mostly there and this Lenovo has a lot more promise for functionality than my old Toshiba Satellite Pro which was doomed to having most of its buttons not work. Overall, success. No doubt I'll attempt to get all the Fn keys working as expected and maybe even do something with the One Key Theatre and Power Management touch buttons (the volume ones work fine and most keyboard Fn keys seem to work also).
