This is a clarification on my previous post. On a sony vaio vgn-fs790, whats strange is I cannot set the brightness using the settings on gnome-power-manager. However, I can explicitly set the brightness by running (as root):
echo "1" > /proc/acpi/sony/brightness (for maximal dimming) echo "8" > /proc/acpi/sony/brightness (for maximum brightness) Hopefully, that helps. I don't know if this is reproducible on other sony vaio laptops. -- doesn't dim screen on sony vaio vgn fs215m (regression) https://launchpad.net/bugs/65028 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
