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.

  • Graphics. The Intel GMA 450 works fine with the official Intel driver without any patch; install xf86-video-intel and start X.
  • Wireless. Here there are issues. This laptop uses a wireless card with the Realtek 8192SE chipset. There’s a driver, but ATM isn’t included into the last kernel, so you need to build and install the RTL8192SE driver. Take it from AUR.
  • Bluetooth. Works! Install bluez package and nothing else.
  • Touchpad. Everything works here too. I setup vertical/horizontal and circular scrolling with two fingers (I never tried it before, it’s really nice!). Just install xf86-input-synaptics and set your config. Here mine.
  • Webcam. I did only a test using mplayer and…works!
  • Audio. ~~To mute speakers after headphones connection I had to add a line to modprobe.conf: options snd-hda-intel model=dell-vostro~~. EDIT: No more needed since kernel 2.6.34.

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!

Cheers!
