Compatibility of Ubuntu 9.04 on Neo Basic B2140-N
Everything important works after few configurations.
Problem Encountered 1: Boot up, Loading Bar Freezes/Hangup. Solution: Add this line nohz=off while in boot grub menu selection by pressing F6, press ESC to remove the pop up and just type ahead along the lines. Using acpi=off noacpi is overkill and will disable a lot of your laptop features such as battery duration/savings/ac adaptor, soft power button and also the Fn keys that access wireless activation, touchpad on/off, sleep, hibernation and brightness control.
If you add this line prior to installation, it will be permanently there. But if you already installed Ubuntu using acpi=off and noacpi instead, you have to edit your /boot/grub/menu.lst and remove those line acpi=off noacpi and replace it with the nohz=off
Other lines to add in case if the problem persist; this will also be helpful in other laptop models without killing the acpi: nohz=off ide=nodma apm=off noresume nosmp maxcpus=0 edd=off I found this fix with Opensuse's Failsafe. It's failsafe option does not resort to acpi=off noacpi nolapic.
My basic laptop's BIOS is restricted, you can only edit the date&time and boot priority. So acpi problems cannot be fixed there.
Problem Encountered 2: Low resolution after installation Solution: Download the driver here- SIS Mirage3 M-672here, and install it, then restart Xserver when you log out or just reboot.
Problem Encountered 3: Fn volume controls and mute goes crazy when pressed. Solution: Reassign the Mute and volume +/- shortcut keys at System>Preferences>Keyboard Shortcuts. I reassign mine at ctrl +, -, 0(for mute).
The built-in Webcam, 4-in-1 Card Reader and Wi-Fi (Realtek RTL8187B Wireless 802.11g) works out of the box if activated. Audio works including the earphone transfer. Monitor-out works except the Monitor-out transfer so the laptop screen will remain on. You can install cheese in the Add/Remove to verify the Webcam is working.
Problem Encountered 4: The Wi-Fi Realtek RTL8187B can connect to the router but there is no internet connection. Solution: You can go here for the fix http://ubuntuforums.org/showthread.php?p=7798209#post7798209
Even though Neo laptops received a lot of bad comments in blogs, I really like mine. No OS included, they stated in their website that they put Linux on systems that do not have Windows pre-installed, this one has Freedos instead.
