Package: base
Severity: important
Wheezy kernel modesetting bug.
I found a workaround for this bug and I am now convinced the bug has nothing to
do with modesetting. It is rather a bug that is caused by a failure of the
kernel to turn on the back light of the laptop (Acer Aspire 7715z).
The workarounds:
a) use acpi_osi=Linux as a kernel parameter and press Fn + Left Arrow to turn
the back light on when it is incorrectly turned off by the kernel.
b) use the command as root: setpci -s 00:02.0 F4.B=00 The above command can be
included in a startup script.
Thanks.

Hi,
closing this bug as it has very little information and is about an old kernel
anyway. If you still experience problems, please submit a bug using
