Quick summary of the challanges:

1. Broadcom wireless card
2. NVIDIA Optimus system with two graphic adapters

1. I have spent quite a bit if time on the broadcom wireless card. I have basically tried all possible "advices" found on internet with various drivers and methods e.g. ndiswrapper, STA driver, pre-compiled from repositories and also I tried to compile myself. Currently, the version of STA driver is 6.30.223.141.

• ndiswrapper found the driver, but WiFi was not active, even though the driver says that device is found
• pre-compiled driver in repositories broadcom-sta-dkms ver. 6.30.223.141-1 discovered all networks and hardware but it was not able to connect to any network - authentication window was popping up over and over again
• my own compilation of the driver directly from broadcom web page http://www.broadcom.com/support/802.11/linux_sta.php was not working due to some errors in the code (note, that I'm 100% sure, that all necessary packages for compilation was installed). I have used this page as a guideline: http://forum.osxlatitude.com/index.php?/topic/6339-ubuntudebian-14e443b1-broadcom-corporation-device-43b1-rev-03/

Finally, you wouldn't believe what was the solution - installation of older driver release. I have downloaded from here:
https://launchpad.net/ubuntu/saucy/amd64/bcmwl-kernel-source/6.30.223.30+bdcom-0ubuntu3
After installation and restart of comupter everything was working like a charm!

2. At the beginning I was afraid, that NVIDIA Optimus Quadro K1100M and Intel Internal card arrangement will be an issue. After I have just downloaded NVIDIA proprietary driver and install it via command line my screen didn't turn on! My mistake! I should first google!

Than I re-installed the system and installed following packages:

• nvidia-prime (latest revision 0.6.2) from Ubuntu repositories
• nvidia binary driver (version 331.38) from Ubuntu repositories

Note, that there has been quite some dependencies selected automatically during the installation. After restart everything was running perfectly.

All other hardware is running out of box e.g. sound system incl. microphone, web camera, card reader etc.

I have to admit, that I haven't still tested bluetooth functionality. Once I do it, I'll update the post. Enjoy!

Just a recent update on Ubuntu 15.04:
I have installed right now fresh install of Ubuntu 15.04. As I can see from Synaptic manager there is this version of wireless driver 6.30.223.248+bdcom-0ubuntu2. The wireless is now working out of box and no need of downgrade is necessary. Similarly to graphics. I have just installed recommended proprietary drivers and all is working like a charm. Good job Ubuntu!
