My openSUSE 12 Journal - 5: Desktop Bits & Bytes

This is week 3 of using 12.1 and still lovin' it.  This journal entry covers a few disparate topics, from wifi to graphics cards, as I go about my daily routine in the office (stuff I actually get paid doing) with openSUSE 12.1 on my Lenovo Thinkpad.

Can't locate your hidden Wifi access point?
Here is a neat command (as root) that you can execute to help NetworkManager connect to a hidden wireless access point OR when NetworkManager is unable to detect your desired wireless point fast enough in a wifi-saturated environment.

iwlist wlan0 scanning essid MyWifi

where wlan0 is usually your default wifi device, if you are unsure, execute ip add to verify.
MyWifi is the name of your desired/hidden wireless access point.  For ease of use, you could wrap this into a nice little script.

My openSUSE 12 Journal - 4: Minor Frustrations

This is my fourth journal entry for openSUSE 12.1 and it has been two weeks of operational use on both my Thinkpad and home PC.  Here are some additional minor frustrations and some workarounds... and yes, I have posted on the openSUSE forums (just in case you'd ask).

Boot 12.1 using the old System V init
In my first journal entry, I complained the lack of "chattiness" during boot since the adoption of Systemd.  You can easily switch to the old System V init on boot.  At the grub boot loader screen (usual 8 seconds delay) and before you hit Enter to boot, press the F5 button to switch from default to System V.  Now, press Enter to boot and press the Esc key during the splash screen to see the familiar System V init messages.

[Update on 6 Dec 2011]: Tired of pressing F5 every time on boot? Append the following to the end of the line:
For example, in /boot/grub/menu.lst, at the end of the line starting with "kernel /boot/vmlinuz-3.1.0-1.2-desktop...", append the line above and save the file.  On the next boot, you can verify the change in the Boot Options field.  Press Enter and you will boot up 12.1 under the old System V init.

Air Video Server on openSUSE 12.1

In short, Air Video is a client-server product that streams, via live conversion, videos of many formats to any iOS device (eg iPhone, iPad etc).  The server software is free-of-charge but only runs on Mac OSX and Windows.  The client is also free-of-charge for iOS devices but "crippled".  If you like the solution, you pay for the client.

Since the Air Video Server is written in Java and uses a customized version of FFMPEG, it would be possible to run it on Linux.  The folks behind Air Video though supportive but are NOT offering official support for Linux. 

I have been successful in making Air Video Server (AVS) work on openSUSE 11.3, 11.4 and 12.1.  Here are the steps:
