Workaround for brightness bug
The Lenovo Ideapad Y530 has an unusual implementation of the ACPI system. A patch to the kernel (2.6.29) is being developed. Until its release the following workaround should help control the display brightness beyond the limited ability of the keyboard shortcuts.
To see the list of available options:
Replace XX in the following command with the display intensity you desire.
echo XX > /proc/acpi/video/VGA/LCDD/brightness
For full brightness:
echo 65 > /proc/acpi/video/VGA/LCDD/brightness
Switching wifi on/off during work
Any ideas? Currently you have to reboot to make it work.
