comment Xubuntu: Disable gnome-keyring
@ZDroid I checked it out, and aptitude had no difference with apt-get. Aptitude also wants to remove both xubuntu-desktop and software-center.

comment Xubuntu: Disable gnome-keyring
@ZDroid Thanks! This brings the Passwords and Keys app to Xubuntu. According to my searches, I thought one can disable gnome-keyring with this app, but now I see this is not the solution. I will edit my question. My mistake!

comment Are there Human Interface Design Guidelines for Unity Development?
Close but then again not exactly what I'm looking for. Some of the above links include guidelines, but others are just descriptive articles about different aspects of the Unity shell. Take a look at GNOME's HIG or Android's HIG that I have linked in my question ... that's the kind of stuff I'm looking for, which seems such a thing is not available for Unity.

comment Are there Human Interface Design Guidelines for Unity Development?
I think my question is clear ... I'm looking for HIGs for developers willing to create apps for Unity.

Did you install the proprietary drivers of NVIDIA (using additional drivers) or you're using the open-source nouvea module?

comment 3G USB Modem Not Working in 12.04
I assumed that UsbModeSwitch is a pre-installed module on modern Linux dirtros! Anyway I found another way to switch the device type, which I will fully explain as an answer.

comment 3G USB Modem Not Working in 12.04
No I haven't tried that script. I was hoping there would be a standard solution to the problem, specially since the device works fine with the previous version of Ubuntu (i.e. 11.10).

I always keep my Ubuntu installation up-to-date (every-day), but unfortunately that didn't make my modem show-up in Network-Manager.

Unfortunately this command didn't solve the problem and still there is no Mobile Broadband connection in my Network-Manager. Thanks for helping anyway.

What should happen after this command ? Should it show-up in Network-Manager ?

comment screen resolution problem
That path is in accordance with the Unity desktop in Ubuntu-11.10 and 12.04 which are based on GNOME-3, and is identical to the path you said which is for GNOME-2. Unfortunately I don't know why you are unable to change the screen resolution in the Display-settings! I will return if I figure out anything. I've edited my answer with some suggestions. That's all I can say for now.

comment How do I fix “Unknown error executing gpgv” when doing sudo apt-get update?
OK, I have edited my solution by providing another fix. If this one doesn't work too, I'm afraid I'm out of solutions for you! But I'm almost sure that one of these solutions should work for you.

Hmm, strange! Currently I don't have any clue why this didn't fix the issue. I will come back as soon as I find anything useful.

comment How do I fix “Unknown error executing gpgv” when doing sudo apt-get update?
The commands I provided are slightly different from those you posted in the question. Carefully follow the commands I have provided. These should work, because I've used this method to solve GPG-errors many times and it has always worked for me.

comment How to boot with Intel GMA500 Poulsbo graphics
OK, I updated all xserver and kernel packages of the live-12.04-beta2 to the recent version (3.2.0-22) and tried again ... it booted with a distorted display. Now, just as the wiki states, I switched to console and restarted X using sudo service lightdm restart and now I have a fine graphical environment :)

I'm positively sure that it's a GMA-500. Today I will try to test it with an updated kernel.

The kernel version is 3.2.0-17. I can't connect to the Internet with my netbook (since my netbook doesn't have an Ethernet port). But I'll try to update this live version on another machine and try again on my netbook.
