Shishir and Avash:
This is due to the ACPI bug in the kernel itself. Some of
the laptop vendors have tweaked their hardware configuration that kernel
does not properly recognize. You can try to get around this by adding
"noacpi" or "acpi=off" as a kernel parameter while booting linux (in
grub menu). Alternatively, you can try:echo <brightness_val> > /proc/acpi/video/LCD/brightness e.g. echo 0.7 > /proc/acpi/video/LCD/brightness Hope this helps. -- Abhishek Singh FOSS Nepal Community http://wiki.fossnepal.org
