Hi guys,
Is there any news on screen handling for sony laptops, especially
the VGN-A290? My machine suspends ok, but although the backlight
goes off the screen itself stays powered up and the battery life
isn't reduced.
I'm running=20
FreeBSD foobar.tao.org.uk 6.0-STABLE FreeBSD 6.0-STABLE #23
with acpi_video.ko and acpi_sony.ko loaded.
The sony module shows up as:
% sysctl -a | grep sony
dev.acpi_sony.0.brightness: 4
dev.acpi_sony.0.ctr: 0
dev.acpi_sony.0.pcr: 0
dev.acpi_sony.0.wdp: 1280
dev.acpi_sony.0.cdp: 0
dev.acpi_sony.0.%desc: Sony notebook controller
dev.acpi_sony.0.%driver: acpi_sony
dev.acpi_sony.0.%location: handle=3D\_SB_.PCI0.SBRG.SNC_
dev.acpi_sony.0.%pnpinfo: _HID=3DSNY5001 _UID=3D0
dev.acpi_sony.0.%parent: acpi0
Any hints would be greatfully received.
Thanks,
Joe
