Keyboard backlight works out of the box but the manufacturer accessory keys cannot adjust ithem. they must be adjusted manually (timeout length) in the BIOS. (z935)
The only big (-ish) problem is that the screen backlight does not work after resume. To fix this do the following:
The fn keys that control the brightness work as long as the laptop does not get suspended. If the laptop is suspended then upon resuming the fn keys no longer work. The fix is as follows:
in the file /etc/default/grub at the end of the line GRUB_CMDLINE_LINUX_DEFAULT (inside the quotes), then run update-grub. After rebooting, this will remove the acpi_video0 from /sys/class/backlight/ leaving you just with intel_backlight and toshiba. Upon resuming with these settings the screen would be completely black with no means of making it brighter. To fix this one needs to create and add the following to /etc/pm/sleep.d/restore_brightness:
#!/bin/bash case "$1" in suspend|hibernate) #do nothing ;; resume|thaw) echo 7 > /sys/class/backlight/toshiba/brightness ;; *) exit 1 ;; esac exit 0
Don't forget to chmod +x the script. You should now have a trouble free laptop :)
If it doesn't work, try disabling the toshiba interface (which is completely useless at least on the Z930-12Q) using
(don't forget to re-execute update-grub, though).
First try booting the kernel parameter:
If that doesnt solve the problem, many folks have gotten mileage from either:
in addition to the earlier mentioned parameter.
If neither of those solve your problem, you should edit/create /etc/X11/xorg.conf.d/20-intel.conf with the following content:
Section "Device" Identifier "card0" Driver "intel" Option "Backlight" "intel_backlight" Driver "intel" BusID "PCI:0:2:0" EndSection
If you are using systemd the Arch Linux fix from above will probably help, but it is untested. Please edit this with test results. In the case of openSUSE, starting with openSUSE-13.1 RC2 (and then 13.1 RC1) with its 3.11.x kernel the power management problems with resuming from suspend are solved.
Installed Ubuntu (09/19/12) and everything worked out of the box. Tested the HDMI and VGA outputs with success, as well as the camera (with Skype). Used both bluetooth mouse and keyboard without any issues. The card reader is working just fine and Ubuntu auto-mounted it. Keyboard backlight and most Fn function keys/features are working (see the 'Comments' section below for more details). The standby/resume made my laptop freeze once. However, it has not happened twice.
Great laptop, if you are willing to add a script to fix back-light brightness and you don't mind a few of the non-essential manufacturer supplied shortcut keys not working
