Hello,
Zitat von Гуляев Гоша <[email protected]>:
Good day!
I have a laptop with FreeBSD 10-BETA4 AMD64. When the power is lost
it automatically reduces screen brightness. But when the power comes
back, the brightness does not return to a normal level. Fn +
BrightUP key do not help. I have no other auto power saving set up
except powerd_enable="yes" in /etc/rc.conf
The only way to return brightness to a normal level now is to
reboot. How I can fix that?
You could try to kldload acpi_video.
# kldload acpi_video
# sysctl -a | grep brightness
should show up a key which you can use to set the brightness.
# sysctl hw.acpi.video.lcd0.brightness=100
For some vendors (e.g. Lenovo) there are custom modules with their own
brightness setting keys:
# kldload acpi_ibm
# sysctl -a | grep brightness
If none of this are working, you might want to try out
ports/sysutils/acpi_call and directly calling an ACPI method to
increase or set the brightness. This was btw the only way it is
working for my Lenovo X121e and E330.
Kind regards,
Matthias
