Installing Trisquel 6 on an X230
These notes refer to installation on an X230 system, model 2306-CTO.
Thinklight and backlit keyboard
Both of these features work as expected out of the box.
Brightness control works using the expected Fn + function keys, however only 6 levels are detected. To control up to 16 levels of brightness, you can add the
acpi_backlight=vendor kernel parameter to the boot options1 :
- Edit the /etc/default/grub file:
$ gksudo gedit /etc/default/grub
acpi_backlight=vendorto the default kernel parameters:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
- Update GRUB:
$ sudo update-grub
Reboot to make the changes effective.

Wireless does not work with 100% free drivers out of the box. The internal half mini PCIe card can't be replaced by a compatible card as this system uses BIOS whitelisting. There isn't a modified BIOS available yet (as of Jan 15 2013).
As a workaround, an external USB adapter such as those sold by ThinkPenguin can be used.
The fingerprint reader does not work with 100% free drivers out of the box.
Several optimizations are needed to maximize battery time. Most apply to any Gnu/Linux distributions, except for running Libre kernels. See Optimizing battery time on the Trisquel wiki.
When testing the newest Libre kernels as indicated on the Trisquel wiki, some functionality was lost (like wireless access and brightness controls)
