Sony Vaio VPCF13
Xorg video issues
X server didn't start properly with Nvidia drivers installed by pacman. I use one downloaded fron Nvidia web. Then I installed them by running downloaded script. After thet, the Xserver runs just fine.
Display backlight regulation
I found this solution - http://code.google.com/p/vaio-f11-linux/wiki/NVIDIASetup. It's for Vaio F11, but it works for my F13 too.
I've added this line in section "Device" in /etc/X11/xorg.conf :
Option "RegistryDwords" "EnableBrightnessControl=1;PowerMizerEnable=0x1;PerfLevelSrc=0x3333;PowerMizerLevel=0x3;PowerMizerDefault=0x3;PowerMizerDefaultAC=0x3"
Plus I use module sony_laptop .. MODULES=(sony_laptop) in /etc/rc.conf
The patched kernel is available in the AUR: linux-sonyAUR[broken link: package not found]
The sony-acpid daemon is also available in the AUR: sony-acpid-gitAUR[broken link: package not found]
Suspend to RAM
While using KDE, suspending uses pm-utils. Because of USB-3 ports it's necessary to unload module xhci_hcd before suspend. This can be done by following steps.
# cp /usr/lib/pm-utils/defaults /etc/pm/config.d/defaults
Then edit the file in /etc/pm/config.d/defaults with SUSPEND_MODULES="xhci_hcd"
