Now a days i hear many people saying that the network manager in jaunty is buggy and they couldnt  connect to internet..So everyone out there before you make that statement please check the following :

—-> Gnome N/M auto-connects to a wired connection when it is plugged in. Does the network-manager icon have “Enable Networking” checked?

—->Normally for all the wired n wifi connections dhcpis used to assign an address…open a terminal and type:

sudo dhclient eth0
dhclient is the program that connects to a dhcp server on a network and asks for an ip address to be assigned to your computer. It is the most common method for assigning ip addresses on a lan.

For people who still cant get their network manager running,here are some alternatives.

You can use xnetcardconfig which is  a GUI program that can be installed and used via synaptic. Although you have to manually configure everytime you boot up,it is a good alternative…

Try installing wicd which is a nice tool for configuring wired and wireless networks..find it here http://www.ubuntugeek.com/wicd-wired-and-wireless-network-manager-for-ubuntu.html

This post has been published on the request from one of our tuxfreaks members ,to install drivers for the Realtek ALC662 audio device. The auto install does not work.
I have an asus x50,and to make my speaker working, I had the following line to the /etc/modprobe.d/options file :
options snd-hda-intel model=laptop

Try running this command:
echo ‘options snd-hda-intel model=laptop’ | sudo tee -a /etc/modprobe.d/options

Then reboot. Mostly your sound works. If not,installing Realtek’s drivers is the only way left

1. Ubuntu Jaunty Jackalope has the new version of X.org server(1.6).So it doesnt support the older ATI graphics card.If you like to have 3D support (compiz/games) ,sorry folks,the open source graphics drivers for ATI do not have 3D support
2. Nvidia drivers version 173 and 177 are broken.Though nvidia people are with their newer versions (180,185),they only work with the newer gpu’s
3. Firefox flickering has always been a problem in jaunty when you scroll the web pages Read the rest of this entry »
