Suddenly this sound “tek tek tek ..” came out from inside the laptop. Wow i was so scared! Then i just turned off the laptop by pressing the power button.
I was wondering what happened. Maybe because i have used it for more than 6 hours? i don’t think so, because a few days before i left it online the whole night.

And now, after Acer Aspire 2920 review *on Windows of course*, I want to share with you how Ubuntu 7.10 runs on it.
At first, it was Mandriva Powerpack 2008 that I had in mind. The installation was OK, nothing ¨that I knew¨ went wrong 
but some of the features didn´t work, like the wifi, the bluetooth, even the shortcuts (Fn + …). Maybe the bluetooth didn´t work in Mandriva Powerpack 2008 because I hadn´t installed kdebluetooth . Well, who knows?! Instead of wasting my time finding out how to fix it (I don´t know how anyway), I started to find the copy of Ubuntu 7.10 that I had downloaded before.
For the complete hardware list you can check out the acer website. Here is the lspci list :

As for the lsusb list :
Bus 007 Device 001: ID 0000:0000
Bus 006 Device 003: ID 5986:0102
Bus 006 Device 002: ID 0bda:0158 Realtek Semiconductor Corp.

Bus 005 Device 001: ID 0000:0000
I am not really sure, what is the Realtek Semiconductor Corp doing there, but I think it is the internal microphone.
As always, Ubuntu never disappoints its great fans. The installation process was perfect. Everything worked fine: the Fn shortcuts, the wifi, the www. The email button also worked. Some didn´t, but I think it was because I needed to set up the buttons first. Even the scrolling on the touchpad also worked. It was just perfect.
After the installation, I rebooted the laptop. It took more than 1 minute for the system to be fully loaded. As a default, Ubuntu always checks the file system of my drive every time I reboot, and the process really slows it down.
Screen : I don´t know what made it this way. Usually, when you look at a laptop screen and your viewpoint is not perfectly towards the middle of the screen, what you will see looks like a negative; it is not clear. But in Ubuntu it is different: you don´t need to sit precisely looking at the middle of the screen to get a clear view. Well, of course you will not get as clear a view as when you’re looking at the middle of the screen, but at least you will not get the negative effect.
Keyboard : Until now, I haven´t experienced any major problems with the keyboard. There is one thing that bothers me a little: on some diacritics like ^ , ´ , and ¨ , we need to press the keys twice for them to show up.
Fn Shortcuts : They worked fine. Actually, only some :p The only Fn shortcuts not working were : Fn + F2 (Acer eSettings Management), Fn + F3 (Acer ePower Management), Fn + F4 (Sleep. It did turn the laptop into sleep mode when I pressed the shortcut, but after that, when I pressed any key, the laptop turned on but the screen was just blank. I still had to turn off the laptop by pressing the power button).
Hibernation : It worked with some trouble. While writing this, I am also running Rhythmbox. I closed the lid, then the laptop went into hibernate. When I turned the laptop on, all the running applications were loaded perfectly, except Rhythmbox. It was still playing the song though. I noticed it from the bar that was still moving, but no sound came out. Then I tried to restart the laptop, and voilà! the sound came on
Easy-launch buttons : Acer Empowering Technology and Acer Arcade of course didn´t work. The rest; wifi button, www button, email button, and bluetooth button worked perfectly.
Volume wheel : I was so happy when it popped up the volume meter
Sound : Not fully working. When I inserted an external speaker jack, the sound didn´t move to it.
Touch Pad : Working perfect, including the mouse wheel emulation. I was even able to zoom documents in Open Office.
Bluetooth : After I installed kdebluetooth, now I am able to send files to my mobile, but not the other way around 
Wifi : Working fine.
Card Reader : I was not expecting this to work, but it did! Wow, I am so happy. Using the command tail -f /var/log/messages, here is the message :
NuGorgom kernel: [ 4295.396000] sd 4:0:0:0: [sdb] 31360 512-byte hardware sectors (16 MB)

Camera : I had installed Camorama. It popped up an error message saying ¨could not connect to video device (/dev/video)¨
Internal Microphone : Didn´t work at all. Tried to record using Sound Recorder, but I got nothing.
Graphic Card : Working but without 3D support. No compiz
Express card, modem port, TV-out, and external display.
I did some checking on some hardware, using the command tail -f /var/log/messages. Here were the results :
