OS: Ubuntu 12.04 LTS 64bit

Forgot to add the Synaptics touch pad rarely keeps the pointer stationary. Again, this is a new development with 12.04LTS.

Version: 12.04LTS
Laptop: HP Compaq nc6220
Issue: Will not suspend according to power management settings. Power management worked well for this unit with versions 10.04LTS and 10.10.

Both issues were resolved with 12.04.1 LTS.

1)Version Of Ubuntu --> Ubuntu 12.04 64bit (kernel 3.2.0-29)

2)Laptop Maker --> Asus

3)Laptop Model --> X54C-261D (15.6", i3-2330, 2+2GB RAM, 500GB HDD, Wifi AR9285, Ethernet AR8151)

4)Known Issue:
Bluetooth almost never worked with Ubuntu, (while it did with Knoppix, Slax, even Lubuntu).
Workaround: blacklisted asus_nb_wmi, due to which, asus_wmi also stopped being loaded.
Side-Effects: Although the BT now works perfectly, Fn+ combination key functions for volume control, mute, and touchpad enable/disable don't work now (due to absence of asus_nb_wmi). All other Fn+ combos work as usual.

Apart from this, the laptop is working great with 12.04, no additional tuning required. (oh, except that it sometimes fails to bring back the desktop after resuming from sleep, tty1 to 6 work though - a common issue I guess )

1) Desktop 12.04
2) HP
3) Pavilion DV8000

known bugs :

- Frequent freezes.
- Wifi driver issue after updtate, can't connect to secured wifi. Won't ask the security key.
- Desktop issues, such as sidebar not loading properly or taskbar invisible/black.

- And last but not least, because of the freezes, hard reset has to be done which is known to be a source of problems with the Pavilion DV*000 serie. It may damage the motherboard, RAM and CPU. It may as well even prevent you from booting your laptop due to residual power to RAM and/of motherboard. (which is my case, I'm currently struggling to boot my computer)

I have a eMachine em250 netbook and trying to get Lubuntu 12.04 wireless to work because of power.
What's funny is that Ubuntu works fine on my machine. I removed the hard drive and installed it in my wife's em250 and it works fine. I must have a different chipset. I tried to install Broadcom b43 but it says to install another but I cant remember which one...it doesn't work. Here is another net mystery...when I plug in a cable browsers cant access the internet. I can go to other computers on my home net. The software center works though. I am able to update and to download other browsers. Any ideas?
