Arch Linux on Toshiba Satellite T130

I bought a new laptop: the ultrathin Satellite T130! I’m not writing a post about this (awesome) laptop, but on how to make it working with your (Arch) Linux OS.

In conclusion everything works fine, but I still am trying to made backlight control working; I added the known acpi_backlight=vendor kernel line to GRUB with no lucky.

EDIT: A man sent me a script to fix the backlight issue. The trick is easy: using setpci you can hack the brightness. Then I set up KDE Power Management to run # setpci -s 00:02.0 F4.B=40 when I am using Powersafe profile, and # setpci -s 00:02.0 F4.B=FF when I am using Performance profile (you need to add the rule to your sudoers file). This is enough for me, you could use a script to increase/decrease the brightness editing the F4.B argument.

Thank you Petri!
