Sony ACPI support for screen brightness adjustment I have a recent Sony Vaio (VGN-C1) running under 6.2 RELEASE First note that sound works very well with the binary snd_hda from Ariff Abdullah. http://people.freebsd.org/~ariff/lowlatency/ 1) seems to work 2) doesn't work at all. Even halt -p hangs before shutting down the computer. I have tried a recent CURRENT, does the same. Once i got in the debugger, the machine apparently hanged while powering down the pccard controller. 3) works with Damien Bergamini driver 20070121-wpi-freebsd but maybe produces memory corruption (tolerable ...) 4) works with kernel module acpi_sony. Only needs to tweak a sysctl to adjust screen brightness, the keyboard key is not recognized. The worse problem is ACPI, it doesn't work OK with Ubuntu either. All in one, and despite memory corruption with Intel wireless the laptop works better with FreeBSD than Ubuntu for me. -- Michel TALON
