Debian wheezy (testing) on VAIO VPCSB11FX

Wireless driver (ref: http://wiki.debian.org/iwlwifi)

• # apt-get install firmware-iwlwifi [need to have non-free in sources.list)
• # modprobe -r iwlagn ; modprobe iwlagn

Enable touchpad scrolling

• Run

  # rmmod psmouse
  # modprobe psmouse proto=imps

• Make permanent: # nano /etc/modprobe.d/options, add

  options psmouse proto=imps

• Note: proto = bare (Bare PS/2), imps (Microsoft Intellimouse), exps (Microsoft Explorer Mouse), ps2pp (Logitech Mouse), genps (Genius Wheel Mouse), targus (Targus Scroller Mouse), synaptics (Synaptics TouchPad), any, auto. (Someone says "Using exps instead of imps has advantages when you like to use your thumb buttons.")

lm-sensors

• # apt-get install lm-sensors
• # sensors-detect --> add coretemp into /etc/modules
• # sensors

ATI propriety driver (http://wiki.debian.org/ATIProprietary) [to make it less hot]

• # apt-get install linux-headers-3.2.0-4-amd64 fglrx-control fglrx-drive [notice the version of kernel headers]
• Quit X
• # modprobe -r radeon drm
• # aticonfig --initial
• /etc/X11/xorg.conf has something like:

  Section "Device"
      Identifier  "ATI"
      Driver      "fglrx"
  EndSection
  
  Section "Screen"
      Identifier "Default Screen"
      DefaultDepth     24
  EndSection

• # startx

CPU frequency scaling (http://wiki.debian.org/HowTo/CpuFrequencyScaling) [to make it less hot]

• # apt-get install cpufrequtils
• # cpufreq-info --> information
• # nano /etc/default/cpufrequtils; add

  # valid values: userspace conservative powersave ondemand performance
  # get them from cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_gove$
  GOVERNOR="conservative"
  

• cpufrequtils has an init script that should load the appropriate driver at boot time. # ls /lib/modules/$(uname -r)/kernel/drivers/cpufreq/ lists available drivers (modules), such as powernow_k6 (for AMD K6), powernow_k7 (AMD K7: Athlon, Duron, Sempron 32 bits), powernow_k8 (AMD K8: Athlon 64, Turion 64, Sempron 64, Opteron 64), p4_clockmod (Pentium 4, Celeron D, Pentium D, Celeron M), speedstep_centrino (Pentium M, Core Duo, Core 2 Duo), acpi_cpufreq (generic driver).
• # apt-get install sysfsutils
• # nano /etc/sysfs.conf, edit like

  devices/system/cpu/cpu0/cpufreq/scaling_governor = conservative
