My Ubuntu 12.04 installation has an input problem preventing me from clicking near the top of the screen. That is, there is an unclickable area, circa 60 pixels high and stretching all the way across the screen. I will ask about this in a later question.

For now, I would just like to be able to connect to the internet, given this limitation. I am able to access the network connections application by hitting the super key and typing "network connections". There is a LAN and a wireless network available.

The network icon in the bar at the top of the screen shows an empty wedge, which I suppose means that wireless is off. I've attached the cable for the Ethernet connection, but it does not seem to have connected automatically. How can I figure out what's going on?

(I'll happily edit in the output of any relevant terminal commands.)

Thank you.

Edited to add command outputs:

eth0      Interface doesn't support scanning.

Final Note:

I restarted the system and the internet appears to work, via wifi, so the problem is solved, for now.

This answer should help you: How do I connect to a WPA wifi network using the command line? the "ssid name" is the name of the network given in iwlist so for you it would be "BTHub3-XPMM"

hope this helps

In the case if its H/W problem just try manually to resize the desktop window. If not possible n u want it to use thro' terminal and u have firefox installed on ur system then directly in terminal type "firefox" it will open the firefox for u.

  • Also using system settings just allocate keyboard shortcuts for various browsers

  • 1) I'm not trying to solve the input problem now - one thing at a time. 2) I'm able to open Firefox and any other application through the launcher using the super key, so that is not the problem. The problem is the internet connection.

What does clicking the top portion of your screen have to do with connecting to the Internet? That happens automatically when Ubuntu "senses" the network connection.

By "connecting to the Internet," do you mean launching your web browser? And you can't do that because your task bar and system/start menu are at the top of your screen? If so, you could press Alt-F1 to open the menu.

  • I think the problem he has is that ubuntu does not automatically connect to a network. So he needs to access the networking menu in order to select a network to connect to

  • A little sensitive, are we? Downvoting an answer because the question is unclear? Wow. Humanity never ceases to amaze me.

  • I didn't mean to be a dick by down-voting. But your answer is pretty much the same as the first one. And if the question's unclear ask for clarification in the comments.
