Oh it boot the OS alright ... but after displaying the pretty Ubuntu logo, bugger just freezed!. I then search in few forums and realized that others are also having the same issue. I honestly don't know what really is the issue here... but for some reason it just freezes the whole screen.
I also had a bit similar issue with my now old Laptop while I was trying Ubuntu 11.04 using the LiveCD but was able to fix it by first not choosing to run Ubuntu as a live environment but went for the installation straight ahead.
|Dudes, I really got in running! :D...|
This time I saw the Wi-Fi card is turned on automatically thus I guessed that it might be the Wi-Fi detection problem which is pretty common with GNU/Linux these days.
Anyhow, just out of curiosity, I decided to give it a try, again, and this time, when the USB boot-menu was loaded, I pressed the "F6" button and chose "ACIP-Off" option. The system booted but when it arrived where previously freeze-d, this time I got an error message (except for the stuck-non-informative window as with previous occasions) saying that the installer cannot find a live file-system to operate.
Now, I'm not an expert on how GNU/Linux Live "environments" work. But when I was creating my Boot-able USB disk I choose the option that says "Discarded on shutdown, unless you save them elsewhere".
|the second option is not selected by default... but I guess most of us just use it thus this is where I made my mistake (at lest I thin this is the reason)|
|Just make sure that you've chosen this one (selected by default)...|
But to be honest, even after considering the power of the included AMD Radeon HD 6250 (256MB dedicated graphics memory, 280Ghz internal clock speed if I'm not mistaken) Unity does feel a little slow since the proprietary AMD/ATI drivers are significantly faster than the open-source drivers, you should install the proprietary drivers if you want the best possible performance out of that GPU.
And also, if you also have this Netbook, then it should be pretty interesting what the upcoming Ubuntu 11.10 could bring from a performance point of view because with 11.10, Canonical is shipping the Kernel 3.0 for the first-time which fully supports the AMD Fusion architecture by default.
Anyhow, the performance even while on the Live USB environment is really good (I'm even writing this post in it!) but it should be even better after installing in the HDD.
So, if you're having troubles with trying to run Ubuntu 11.04 Natty Narwhal in Acer Aspire One 722 Netbook, then while creating that USB disk, just try the default settings as shown in the third screenshot. Good luck.
Oh and one more thing, the 11.6 inch display has a a resolution of 1366x768 thus things could look a bit too small for some but thanks to the Ubuntu or the Gnome desktop's DPI settings, I think Ubuntu Linux looks + makes things slightly bigger than the original MS Windows 7 thus Ubuntu is certainly my preferred choice while using this Netbook.
