Title:
[HP ProBook 4540s] brightness control problems
Status in “linux” package in Ubuntu:
Incomplete
Status in “linux” package in Baltix:
Triaged
Bug description:
I bought a laptop in December 2012, immediately tried to put Ubuntu
12.10, got broken wi-fi and non-working graphics acceleration. Updated
kernel to version 3.6, with graphic acceleration was all right, even
partially earned wi-fi. After some time wi-fi hang, helped only
restart the network subsystem.
Updated kernel to 3.7, with the wi-fi was all became normal, but
stopped working brightness control with the Fn keys. Progress bar
indicates that the brightness changes, but in fact nothing happens.
Tried the new distribution 13.04, on 3.8 kernels, 3.9, 3.10, nothing
changes. Upon adjustment has broken in 3.7 kernel. It turns out that
this is a regression.
WORKAROUND: Problem gone with kernel parameter acpi_backlight=vendor.
