[Bug 1208257] [NEW] HP ProBook 4540s brightness control problems
Public bug reported:
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.
Hardware Configuration:
Intel Core I5 3210M
Intel HD 4000
8 gigs of ram
Ralink corp. RT3290
Ubuntu 13.04 x64
