Public bug reported:
On Ubuntu 12.04 and Ubuntu 12.10 the Sputnik kernel is used to enable
Bluetooth, Wi-fi and screen brightness on the Dell XPS 13 Ultrabook (it
also enabled the touchpad on 12.04). Even with the latest kernel as of
this writing, Linux 3.5.0-18-generic #29+kamal11~DellXPS-Ubuntu SMP
x86_64, which is the Sputnik kernel from ppa:canonical-hwe-team/sputnik-
kernel, using the default key combination (F2 or Fn+F2) for wireless
turns on Bluetooth but not Wi-fi. The Wi-fi can be enabled via the
graphical interface on most non-Unity desktops, but since the graphical
option for Wi-fi remains disabled in Unity, only 'sudo rfkill unblock
all' can enable Wi-fi in a Unity environment. However, the problem
remains with the Sputnik kernel. I could not find a way to report this
bug in launchpad.net/~canonical-hwe-team, so I am reporting it here. The
specifications of my laptop are as follows: -
* Dell XPS 13 Ultrabook (13" screen with 1366x768 native resolution).
* Intel Core i5-2467M CPU @1.60GHz x 4 (quad-core)
* 4GB DDR3 SDRAM
* Samsung SSD PM830 mSATA 256GB hard drive (SSD)
* Intel HD Graphics 3000 2nd Generation Core Family Integrated Graphics
Controller
* No ethernet port
* 1 x USB 2.0 port and 1 x USB 3.0 port
* No optical drive
The distribution I am currently using is Kubuntu 12.10 amd64
The software details are as follows: -
Kernel package: linux-image-3.5.0-18-generic version
