@bryandeng Ubuntu 14.04 uses the package 'ubuntu-drivers-common' instead of
12.04's 'jockey'. That is why jockey and 'ubuntu-drivers-common' are marked
invalid for Trusty and Precise respectively. You shouldn't have changed it.
I'm also using BCM4313 which from 3.10 kernel onwards works better with the
open source brcmsmac driver in kernel. No need to install
'linux-firmware-nonfree'. Doing lspci shows b43 in my case too, but I don't
know if it should be blacklisted.

SRU request:
Please accept jockey_0.9.7-0ubuntu7.15 into precise-proposed.
[Impact]
Kernel versions higher than 3.11 ship with a good open replacement for
the proprietary driver, which seems to work on many systems that were
quietly dropped by the proprietary driver. We should default to the
open driver when this is the case. This will only affect 12.04.5.
[Test Case]
1) If the broadcom driver is already installed, make sure to remove
it:
sudo apt-get --purge remove bcmwl-kernel-source
Then reboot.
2) Make sure that "linux-generic-lts-trusty" is installed:
sudo apt-get install linux-generic-lts-trusty
And reboot.
3) Test the automatic installation using the following command:
jockey-text --auto-install
and make sure that Jockey does not install the broadcom driver
[Regression Potential]
It should be minimal (and affect only 12.04.5). The open broadcom
driver should already work out of the box.
Furthermore the test suite now covers this test case.
== Description ==
The propreitory driver Broadcom STA (packaged as 'bcmwl-kernel-source',
provides 'wl' kernel module) gets autoinstalled upon Ubuntu 12.04.4
installation on systems with Broadcom BCM4313 (14e4:4727) wireless cards. Upto
Ubuntu 12.04.3 with 3.8 kernel, this was good behaviour. But, with 3.11 kernel
used in Ubuntu 13.10 and Ubuntu 12.04.4, the official open source 'brcmsmac'
driver had improved (with the newly implemented AdHoc and AP mode, and other
improvements) over propreitory 'wl'. On newer kernel versions, 'brcmsmac' works
better than 'wl'.
Autoinstalling the 'wl' driver would actually be a "downgrade" of
functionality. I understand that there are some cards work only with 'wl', but
it's better not to do autoinstall of 'bcmwl-kernel-source' on the ones
supported by 'brcmsmac'. It maybe offered on the jockey Additional Drivers
list, though I don't see any reason why anyone would prefer 'wl' over
'brcmsmac' now. I don't know if this issue remains on Ubuntu 14.04LTS's jockey
merged with 'ubuntu-drivers' package. But, if it does that has to be fixed too.
I hope this issue is fixed soon, so that Ubuntu 12.04.5 is released with the
fixed jockey.
